This Is A Preview Only - It Is Not A Valid BS7671 Certificate Form

hello I'm JW I'm continuing with the certificate series this time going to have a look at the electrical installations to the get or AIC now this is the one that you would use and you put any kind of new things in so that'll be a new circuit or maybe a new consumer unit or entire installations of course consisting of both of those things and this one is quite a lot more in-depth there's a lot more pages to it and it course has a lot more test results and other things included on there now here's an example of the electrical installation certificate and as in the previous episodes this is one from the wiring regulations so called the model version of it and say you're going to buy these obviously on a pad or software whatever then they may well be in a slightly different arrangement that so these are to come in three separate parts so the first part here is the actual certificate itself with assets or more general details on there and so this is two pages in this particular case this one has several sections for people who constructed inspect and tested and of course designed it as well you can't get these with just a single section because in many cases that's going to be the same person doing all of them at this so being the Wadley has the separate section so it's totally possible for one person to do the same design of it somebody has to actually construct or install it and yet another person to actually do the inspection and testing so in this case that's two pages there and then in addition to that we've also got this part which is the schedule of inspections and this is basically just a list of things which you need to confirm are actually done or in some case is not applicable most of these is just ticking off the appropriate things here and again some of these don't apply to every installation again that some of them definitely will and again in the model here it's actually a two-page document others may vary a bit because they may have a slightly different layout so that of course goes with that and then the third item which is this here this is the test results and these really apply to the individual circuits within the installation and he only got a listing of the circuits here and you can obviously fill in the and details for each one so again it could be just as smaller say one circuit or it could be a whole list of these and you can actually get continuation pages for these as well if there's even more circuits to do so three basic parts to this now if you're to go and buy certificate pads some of them will have all three of these within the same pad but some manufactures do have it separately so you have to buy these sort of test results things as a separate set now then things like the actual inspections thing may be separate as well so if you're going to buy pads of these things do check what's included because they some people don't include the test results with it you have to buy that as a separate item and also bear in mind that even if it is included you may need additional sheets anyhow because if you've got a lot of circuits cause there may not be enough space on the form given for all of them so it may involve say buying a two or three different sets of stuff now as for just go through this and fill this in with some sample information and again deliver this is quite obvious so not really any too surprising here so starting with the actual severe part itself then we just need to fill in the details of top here so first of all got details of the client so this is generally the person who's requested the work and they may or may not live at the installation address of course in many cases they do in fact live at the same place that they mind that so if you would say a business it's not likely that the client is actually residing at this address and of course it may be it's a it's a landlord or something you live somewhere and the address of course is somewhere else and it's the reason for the two sections so what is fill in the details here so the name of this person is mr. e WIMP there and in this case it's going to live at the same place so the address in question is 29 Ocasio Road let me come to the description of the installation and this really is just a quick summary of what the certificate was actually about so in this case we'll say that it was a entirely new one and for the extended station covered there we can put in here all fix wiring and they consumer units now of course they can be other things put in here you may have just added a circuit so it'll be just putting in there and adding a new circuit say for a shower and in the case then it would cover just the shower circuit itself may cover a shower target and and you can see many as if you fitted a say small separate one for that so hideous question describing the most applicable things I know on the side here I've got three boxes one of which obviously does apply so in this case it's going to be a new installation because it didn't exist before but he only could have something that you just added to something that was existing or even you've altered an existing installation and alteration might mean say if converted say a ring circuit to two radios or you've changed some of the protective devices so they had circuit breakers previously you've put our CBO's in there instead or something along those lines and for very large or complex things you can of course use a continuation sheet in which case you just put the number appropriate in here two pages one two or three or how many you've got now this piece here which is for design this is very similar to what we saw on the minor work certificate so essentially it's just confirming that it's going to comply with the regulations as stated here and also that you amended to date which in this case will be the 2015 Edition and again you would fill it in as appropriate the reason is 2015 is because if you look on the phone here it's the 2008 edition or the 17th edition and it's amendment three which came out in 2015 so of course you're just filling out appropriate if it was the original one then it wouldn't be an amendment part yeah I'll see if it was one of the others then you would fill those in so just whatever is on the appropriate amendment if applicable and as with the mind works when we got here details of departures and essentially is anything that isn't compliant with the regulations and again there normally wouldn't be anything in here because generally the idea is that you're going to comply with the regulations but there are a couple of instances where you might put something in there and one 20.3 which is one of the regulations it refers to it says any intended pasture from these parts require special consideration by the designer of the installation and shall be noticed on the AIC specified in part six which is the thing with shutting in and the resulting degree of safety installation should not be less than obtained by compliance with the regulations so essentially you can do things which are not in the regulations or don't comply but you really have to have some evidence to show that it is actually going to be safe or at least as safe as the regulations themselves so that's actually quite difficult to do but nevertheless there is a provision for that to be included and the other possibility is this here which is one three three five and their new materials and inventions and essentially it's where that if something was used in the installation that didn't actually exist at the time that this particular book was published then you can use it providing again that the resulting degree of safety of the installation is not less than obtained by compliance with the regulations it's of course new things are it's due some time to time and it's quite possible at some method of installation or some piece of equipment or method of connecting cables or whatever didn't actually exist when this was written because they are subsequently been invented or whatever and therefore you may use it again that's fairly unlikely situation because generally if new stuff is invented or introduced it's only added in the regulations reasonably quickly so not particularly useful so in this case we're going to put not applicable because say most of the time that is what are we putting in let me have details of permitted exception which is four and one three three and that's what the minor works difficult is the deal with our CDs on socket-outlets and again you could have some which didn't necessarily I one would have to be labeled or what a risk assessment done and attached so pretty much the same in this case again we'll put them all and then you've got down here these signatures so here's the signatures for the person or persons designing the installation so a signature date and of course name in there so anyway just sign here put the date there and again you put your name in here like that and if there's more than one designer you could obviously put their name in here and of course continue on if they were more than one now the rest of this here is essentially just a copy of the design section which we've got here so that's the person or persons done the design then we have a section here for the actual construction or installation of it and then we have another one here for the inspection and testing and the same many cases these can be the same people and you can buy certificates which just have a single section which covers all three in the same part so in this case it would be plus three different people that you could of course fill in the same details for each one now the bottom here we've got are we the designers recommend that this installation is further inspected and tested after interval of not more than so many years or months now for most normal installations the usual thing is ten years so just question of deleting months and putting ten years in but babe and it's not always ten years there are other institutions which require inspection more often and it's typically things which you will expect to be say more temporary safe as a building site tempera installation then possibly something that three months would be more appropriate and again you can do five years for certain ones and various others but generally in case it's going to be ten years for brand new sort of normal installation but do bear in mind there are others where less than ten years would certainly be appropriate they're moving on to the second page on this particular model example and we've got here the particulars of signatories to the electrical installation certificate and this is essentially the details of the person or persons who had signed on the previous page so in case you've got the designer here possibly done and up to the person who constructed or installed it and the person who did the inspection and testing so again it's just name address company postcode and of course telephone number so again you just fill those in as appropriate and as before if you've got a certificate it's just a single person doing all of it then you'll only have just one section for that rather than the four that we have here now we've on to the actual electrical parts of the stevia here and first of all got supply characteristics and earthing arrangements so earthing arrangements over here we've got a selection here of five at different items again it's just a question of ticking the one particular to the installation you have now if anyone at TNC is not generally permitted for use in the UK so highly unlikely ago using that and again IT is permitted but it's a very unusual choice to have a centre that misses it's it's isolated from the earthing either by completely isolated or connected to earth why are very high impedance and again that's more of a specialized item the vast majority of installations will be one of the three in the middle so TNS we've got the earth coming in there's a separate conductor TNCs where it's combined the potential conductor when it comes in and the neutral or TT which means you don't have an earth at all it's putting your electrode in the ground so you end just taking the one that you have to have on the installation number and type of live conductors two choices here's our AC or DC most installations we ACR though of course it's not impossible to have DC this case will say it's an AC installation or alternating current and then we've got some choices here as in the number of phases and the number wires that are used for lease apply now for a single phase installation it's going to be one phase and of course deployed on two wires because that's the only way you can do it and the two wires being there would be line and neutral two phases stations are fairly unusual but they're not impossible I think I may be spied on the three wire deal which would be the two phases or two lines and the neutral three phase which is going to fairly common thing on larger installations you've got two options here you've got three phase three wire which would just be the three lines and no neutral and of course three-phase four-wire is the three phases and a neutral as well so again just question of ticking the appropriate one here there's a guess we'll say it's a single-phase installation with the two wire supply now we've over to nature of supply parameters now notes here we've got note 1 which is by inquiry and that applies to the first two things here and no.2 says by inquiry or by measurement and that's the two items here so for the first two you're not actually measuring these you're just basically writing down what they are stated to be by the electricity supplier now in the UK the frequency is 50 Hertz and the voltage it's going to depend on whether it's a three phase or a two phase or single phase whatever for a single phase installation is 230 volts if it was a three phase then that would be a 400 volt arrangement now the second two here you can either do by inquiry or by measurement so you can either find out from the electricity supplier what these were or you can obviously measure these fill in the details we have specially fault current is essentially the current which would flow if there was a short-circuit and I started between line and neutral or between two lines on a three-phase installation or in obviously in some cases between line and earth but generally you'll find that the falcone between line and neutral or the two phases is the higher and it would call the higher value in here and again the external loop impedance is going to be the impedance between line and earth and that's node to the external to the installation so let's measure that way enters the property or the origin of the installation now if you actually inquire with Leslie suppliers for a normal single phase supply they will give you figures here which are 16 ka and then this one depending on the type of supply its are they going to be nought point three five for a TNCs or probably not 0.848 NS supply now in most cases it's not going to be anything like 16 ka on a normal sort of small size single-phase supply so that you can put that in there the realities are it's highly likely you're going to get that so most the time you only better to measure these and it's also useful to actually measure these to confirm that the earth is actually connected because the presence of a wire of course doesn't really mean a great deal so in this case we'll say that you measured the external loop impedance here as say naught point 2 ohms and perspective fault currents we could say was say four point eight okay a and at 4000 K or killer amp so it's 4,800 amps now we've on to the supply protective device and this is generally going to be the fuse which the supplier has provided at the point of it coming into the building now in some cases you won't be able to know what this actually is because of course to know what this is you've got to open up the cutout generally and have a look inside and there's normally sealed and you're not actually supposed to open them so in all the cases you can just put on here not available or don't know and if you do have some happen to know of course you can then fill in the information now there are two ways to get this information say one of which is to open the cutout and actually look inside that's not supposed to happen but course in many cases it does and the other way is to actually ask the supplier what the thing is actually in there so but again in some cases you may not actually know particular dmsa just add a circuit to an existing installation fairly unlikely gonna be pry open sealed cutouts and having a look inside now in most cases the type will just be a fuse not in every case and this here is the basic the standard to which the fuse actually is made and there's a very fond of these the most common one here will be 1361 come to the fuse service gate it's an 80 amp fuse the most usual values for a small installation are 60 80 and 100 again using a chassis look at the fuse to find out because they were just guessing bang mind that most cutouts certainly for single-phase have on the outside 100 amps on there that does not mean that there's a hundred amp fuse in it it just means it could have up to 100 amps put in in many cases it may say 100 on the outside but there may be a 80 or 16 inside so again you do need to actually look and confirm other things here confirmation of supply polarity that's just question of ticking once you've done that and that's making sure that the line and neutral are in the correct places not anything to do with negative and positive because there is no negative and positive on AC if it was a DC supply then it would be negative and positive run again that's a fairly unlikely situation and other sources of supply as detailed on the attached here if that was applicable then you would need to attach an additional document which refer to the other sources of supply and the most common option here would be things like solar panels or of course that's a different supply to what's coming in from the street and other things here you could have say would be generators or UPS systems and things like that okay so this one we don't have any of those so not going to be taking that moving on to particulars of installation referred to in the certificate meetings of everything two choices here distributors facility which is definitely going to be a political here because it's a TN CS supply and again it would also apply if it was a TN s as well and if not then it's going to be the earth electrode which will have installed yourself so connect sticking one or other those definitely not both of them maximum demand or make some load on the installation again this is the diversity kind of arrangement so it's not just adding up the total rating of all the stuff in the installation it's also making allowance for the fact that not everything is going to be switched on at the same time and it is definitely not just adding up the rating of all the circuit breakers in the consuming in it because I gonna give you a massive figure which is never going to be reached so in case this one was say it was 45 amps and it's not going to be KVA in this particular case you could use either the reason it's KVA and not watts is to do with power factor because the thing you're really concerned with here is the actual current that's flowing through and the power factor will that affect their current relate it to the actual real power so 45 amps in this case or whatever you've determined it to be and if you had tix installation of electrode you would need to fill in this section here with details of the electrode type again I suggested here at either rod or rods you can have tape there and ground or say grid or something else buried in the ground there the location of it this is important particularly things like rods because they can get buried and concealed so name is out in the garden or something so a decent description of where that's located and very important is the resistance to earth and again that will be derived by testing the insulation electrode or whatever and then filling in the result here in ohms at this case there we don't have one of those so not applicable now have main protective conductors so the earthing conductor which is the one from the means of everything that we just saw and like an x2 you're consuming it or whatever else now material most cases that will be cop out it doesn't have to be copper but that's per certainly the most common choice and cross sectional area or CSA in square millimeters that again depends on the type of installation you have most smaller installations that's going to be in the region of 16 square millimeters we're paying in mind it doesn't have to be 16 other sizes certainly are available and they could be larger or even smaller than that depending on the type of installation you've got and connection and continuity has been verified in other words you have checked and made sure it is actually connected at both ends early on even normally to check that with a meter to confirm that it was a suitably low resistance infantis close to zero as possible and pretty much the same with the main protective bonding conductors - extraneous conductive parts again generally those are going to be copper 40 and CS installation the minimum is in fact 10 that square millimeters and that's generally what's used but again it may be needed to have those larger in some cases and on sometimes installation particularly TN s or TT they could actually be smaller and again you're going to verify that those are connected and obviously secured in place properly and then here is just saying what B main protective bonding conductors are attached to and again here it's not necessarily all of these things but it's certainly going to be some of them water pipes seems a fairly likely item else does yes coil installation pipes caught if they were saying oil boiler and big oil tank outside of the attack pipes coming into the building structural steel would apply saying on a warehouse type building which was course made entirely from steel to lightning protection if the building has such a thing then it does need to be connected as well and there are other types of things you could have there and if that were the case you would need to write them in and take the box as well now until fairly recently there was almost inevitably going to be water and gas there not every property has gas so course you wouldn't take that in the case of an all-electric type of place but more recently water is generally putting in plastic piping now from the street and even inside the building as well so if it was one of those you wouldn't have it connected there because there's no point connecting bonding conductors to a plastic pipe so of course water doesn't always apply and say if there's no gas installed well again that's not going to apply either the gas doesn't generally come into the property and plastic plastic that is used outside underground now I have details of the main switch or switched fuse or circuit breaker or RCD depending on what you've got now this is the deal which disconnects the entire installation and installation referring to whatever's covered by this certificate so it could be the entire thing in the building or we could this be say if you put a shower unit in and just put a single consumer him just for the shower then it would be the main switch for that particular thing as that would be its own installation it's completely possible to have more than one installation in the same building and location is basically where this switch is located and in most cases that's going to be where the consuming it's also located so it could put here and the stairs popular place in plenty of buildings number of poles is how many pole was the switch has for a single-phase installation that's generally gonna be two sets the line and the neutral begin for other things here three-phase installation could have three through just the three phases or four if it was the three phases and neutral and this BS en here is referring to these standard number two which the main switch or whatever it is has been manufactured now on new devices that is actually generally printed on the front or the side of the switch itself so it's question is looking at the switch and copying down that information now if you don't actually know when it isn't printed on the switch for some reason then in the regulations though is actually a list of all of these standards you can just refer to and the most common one and for things like switches is this one in here 6:09 for 7-3 an associate's four switches disconnectors switch disconnect as and fuse combination units and there's various others throughout here and this section actually covers a considerable number of pages so that'll hold those of different standards in here for switching all kinds of other things as well so if you don't actually know that they mined in Penix one many pages of all of these various different standards and it tells you at journey what they are and or they actually apply to so in this case we'll say two they're fairly new one and of course it's going to be the 609 for 7-3 and so that is by far the most common just for a normal switch or isolator current rating is the rating of whatever this thing is here let's go say it's 100 amps you know that's a fairly common value but yeah and it does need to be whatever is on the thing because you can get so much i rated higher and also some which are rated lower voltage rating again that's going to be printed on the thing itself in this case we say it's a 230 volts and you cannot 404 a three-phase some older ones of art a 240 so again just one of us printed on the thing itself now this middle bit here if it's just a switch does not apply because switch doesn't have a fuse or whatever rating or setting so that's going to be not applicable however if the thing you're using is the main switch was a circuit breaker then you were put in here the actual tripping current for the circuit breaker and again if it was a fuse then that's where the value of the fuse would go in but in this case it's not applicable because a switch doesn't have a rating it will try that it's just question if it's hundred rating before the actual switch mechanism itself it's not gonna actually trip at any kind of current and it's just worth mentioning that the sitting part applies because some larger installations do have a main switch or circuit breaker which can be adjusted so it's not necessary that you buy the things they rated to 400 amps it may well have some adjustment on the front where you can set the range or operation to one of several values so again do we need to put in there what it was actually set to and over here if the main switch is an RCD which is a fairly unlikely situation then you would fill in here the values for the RCD in this case we must say it isn't and again it's fairly unusual to have that because it's generally not recommended how a single arseny covering the entire installation because then any fault would of course disconnect the whole lot but again me for something like I'd say a shower installation or something and only supplies one circuit then you would fill in these here so it's gonna be the operating current typically 30 milliamps any kind of time delay if there is one and of course the measured operating time at the tripping current you put there or in this case we don't have one of them so it's gonna be not applicable and that is that then finally here we've got comments on the existing installation now in this case we've picked up that it's actually a brand new installation so this will be not applicable because you can't comment on something that doesn't exist that's if it was an existing one then this is in the case of additional alteration see section 6 3 3 here is section 63 and since you're saying that the requirements of section 61 and 62 for the issue of no electrical installation still yet works Divya shall apply to all of the work of the additions or alterations and again the contractual person responsible for the new work or the persons and so on shall record on the election installation still get any defects found so far as is reasonably practical in the existing installation so if you'd say added a circuit to an existing installation and you happen to notice there's a few problems with some of the other circuits that is where you would write such things down and again here the section 61 and 2 already so it's just a question of the basic information about verifying there and the initial verification under here so in this case it's a new installation so not going to be applicable and the bottom here the number of things we're attaching which are going to be the other sections we're going to look at in a moment so we're gonna have one of those and we're gonna have one of those and they've had a lot of circuits you may miss any two or more of these depending on how many pages were required now the next thing you would complete is the schedule of inspections and this is basically a list of first number of things which you need to inspect and confirm we're in good condition or have been done or installed correctly and it's got two options here that says for note to you why they're just going to put a tick in the box as appropriate once you go see check that thing is correct or in some cases put not applicable because not all of these things will apply to every installation now I'm not just going to go through this in this particular video because this is essentially the same kind of thing that you would use in the EIC art or the electrical installation condition report we're gonna have a look at that in more detail in another episode so for the moment just gonna say that we do have to obviously fill all of this in and the second page as well say we're not going to go through this in detail here as this video is already a fairly lengthy then the final part is the test results and these will be for the circuit or circuits that you have installed now if you had a replace to consume in it on the existing installation but not put any new circuit in the stickers here will be the ones that already exist in the installation because if you got to put a new to consume unity and you're effectively changing the protective devices typically from fusers to circuit breakers or our CBO's so you do need to actually test all of the circuits on the installation as part of doing the consumer installation are you definitely not a case of just sticking on the wall and shutting the wires in and hoping it works now at the top here if there's only a single distribution board or consumes in the installation most of this is actually gonna be the same as you put on the initial sheet here so things like the default current and the impedance and so on it's all going to be pretty much the same stuff now the only reason these will be different or is if you had in station whether there's more than one distribution board or more than one consumer unit okay so those these would represent the situation at the origin and then these would represent the situation at the individual units or whatever wherever they would be but in this case they are going to be the same so it's just a question of filling in the same information here such as the location of it the loop impedance the fault currents you did confirm the supply polarity phase Super's compare where appropriate in this case not applicable because obviously a single-phase installation details of test instruments used normally this is just the serial number and if you want to use one of those multi function tester which most people use now then the reality as those are all going to be the same number so we're just right in the sewer number of that and possibly the type of equipment you used and yeah that's going to be the same for all of those not necessarily electrode because of course if you haven't got one then you're not going to be testing it tested by signature on date well yeah that's just the name of the person in question and then in the middle here details of the circuit sounder installed equipment vulnerable to damage when testing now allegedly some equipment could be damaged and it's mainly what we talk about is the insulation resistance test when that's applied until you but say 500 volts on the circuit and if you put 500 ec on certain bits of equipment they may be damaged I say may because in most cases they're not the most common thing here would be a smoke alarm and those were generally installed on a lighting circuit or similar and you put down the circuit as well so you put a circuit number four for example and I prefer to the things down here they're the most common there are other things as well which would be installed there and generally have to remove those from the mounting plates before doing any of these tests and then we have the actual test results and again all of these will be obtained from the tests that you've done on the particular circuits using the test equipment you've listed up here so on the side here circuit number I'm going to say this is second number one you can have the one two three four five whatever or ABCD and E or whatever system of numbering you want as long as they're clearly identified now description just a short description of its purpose so we could say kitchen sockets now this promoter form has a bit of a fail here because what we're asking for here is the standard number to which the overcurrent device is manufactured and as you can see the box is incredibly small you're not going to get very many digits in there and again as before the standard number is listed in the regulations and there's first things you would also see right in there depending whether it was a fuse or cartridge fuse or circuit breaker or our CBO or whatever now I put this in here for now what we'll come back to that later because we're not gonna be able to write a great deal in there but for the case this one we'll assume it's a circuit breaker type is the type of circuit breaker going to put in this case going to say it's a type B put a clamp type C and type D as well and even times K&Z but not likely to come across those rating amps so that's a 32 amp device braking capacity this is normally shown on the front of the device it's typically in a rectangular box with a number inside and the numbers usually say something like six thousand or ten thousand and that refers to the amps so in the case this call might say it was six its ka so it's six thousand amps there and that's the some kind of fault current that it can break that is related to as we saw on the front page here the prospective fault current so in this case here formulate ka is the maximum current flu with a short circuit this sucker break you can break things say up to six ka so that's perfectly fine now reference method the conductor details this is how the actual cables or conductors have been installed everything else has a whole list of them inside the regulations here and you see there's a whole load of these printing down the side here and again this whole piles of these provided on pages so again a section of picking the appropriate one item this Alma so it's method C which is as the where K was are concealed within a wall or plastered over or whatever sides are conductors the live conductor so that's the line and the neutral okay so say it was 2.5 square millimeters and the circuit protective conductor or the earth conductor and again the size for that one will be 1.5 because they're using some twin an earth cabling where the conductor is of reduced size compared to the others now if the test results section not all of these will apply to every circuit now this particular say hey we're going to say is a ring final circuit because it's a 32 point one you know it's using a 2.5 square millimeter conductors so in this case ring the final say continuity it does apply and are shown in the testing video this is essentially the resistance of the three conductors so r1 is the line conductor or in its neutral and r2 is the circuit protection conductor or the earth conductor so you would get these from I'll see testing the circuits and there's question of writing those in so so no point seven point seven for that one now continuity you've got a choice here R 1 plus R 2 or r2 now it doesn't matter which one you do but again II do need to fill in one of these in case of the ring because it's say being at its most community the r1 plus r2 it is essentially the line and the protective inductor basically combined in a loop then we would fill in those ones in your point four in this case and r2 where you can just leave blank if you did r2 that's just the resistance of the protective conductor then you would fill that one in and not this one you definitely don't want to be filling in both in because that would imply you're either done both of those tests which is a big waste of time or more likely the person didn't really understand what they were fitting in insulation distance I've said there that's the 500 volts usually between the various conductors and again again frightly absorption in mega ohms so you got two boxes here live to live and live to earth so we're going to write those in here say oh say it was 200 for both their polarity you know that's whether the line and the neutral are in the correct places so they are or they're not so take to confirm that they are now can't say less which is in ohms and this is the system impedance syntax for the circuit plus the external impedance we saw which was said II previously now there's two ways to get this in the case here because we've already got the r1 plus r2 value so it basically covers the part for the circuit now we already know that over here we found that the external impedance was not point two we could just add not point to channel point four and then of course we could get the result of not point six but essentially measuring the same thing as it's just that we've measured the two parts separately it's just some of them if you wanted to you could also go to the sockets and measure that and again you should get a pretty much the same value as well so it doesn't really matter which way you get it provided you either done the test here and of course the external one if you'd only measured our two here then you would have to go and most you measure that because you can't add that because it's adding up the wrong thing our 2d tests first one here is the tripping time so you've got the tributary milliseconds at the rated current survey that 30 milliamps there and he were just filling the time from the testing device so this was 27 milliseconds and then the test again at five times the rate occurrence so in the case of a 30 min of our CD that would lead 150 milliamps again you do the test and write that in and test button operation does it work so when you press the button does it trip then yes it does and you could also put comments in here if there were any which were appropriate you can in most cases that's not going to be required and then you just continue fitting it down here with the additional circuit so you could have another one here for the cooker circuits ample and the lighting and then the shower and upstairs sockets downstairs and all kinds of other stuff and just basically filling in the whole lot all the way down now the only thing to note here is that ringing the final so continuity only applies to ring final circuit so it's not applied to the vast majority of them so in most cases those will just be left blank all the way down and so unless it is a ring then pretty much you're not going to be filling those in those again is one all the other and the other ones generally do apply to pretty much all circuits if there is no our city then again you don't obviously fill this in but as we talked before pretty much all new circuits are going to have one so most cases that will be required now the BS or en number as it's impossible to write in there I'll just show you some of the more common examples which you will come across the first one at which is six zero eight nine eight and that is a circuit breaker also usually called an MCB so the device that just trips off when there's a short-circuit or overload these are generally printed on the front of the devices or on the side as well so again it's fairly obvious to get those the other one which is fairly common is six one double O nine and that is an RC vo so basic it's the circuit breaker and RC D combined in the same device and again that's the number for those ones you can see now why with five digits there was absolutely no hope of writing into the tiny box provided on this example so the newest stations those are by far the most common things to be fitting so just a standard circuit breaker all the combined item they're all the ones that you may have fuses the most common fuses are 1361 which would be a cartridge fuse now he can still buy those although it's fairly unlikely we'll be putting them in a new installation that certainly not impossible and the other one which is fairly common is 303 6 which is a rewire or fuse now in theory you can put very well refuses on brand new installations but again it's horribly unlikely but quart old ones it's a fairly likely they'll still gonna come across those so those four are by far the most common ones to come across so the circuit breakers breakers and our cities combined in a single unit cartridge fuses and of course the reward with users where you have to get out the old bits of fuse wire and thread it through and tighten up the screws and all that as for if in doubt then there's a whole list of them in the regulations in Appendix one goes over many pages so this question of funding the appropriate item and have a look in here if we go here's the 303 six so swimming close literally fuses rating it's 100 amperes and before de volta to earth and so there's many other types as well being why not all of these are for protective devices they're for many other things as well but pretty much they're all going to be in there unless it's some really weird an obscure item so for example circuit here we should have written in here 6/8 9/8 in the extremely small box there that I can see it's not really big enough fully purpose-designed so that's the EIC or electrical installation certificate and in terms of things like the test results you would generally fill those in as you were actually doing the tests so you wouldn't necessarily go on to the end and do them all at once but you'd write them down as you did each circuit and most of the other information on there is gonna be found on things like the main switch and the circuit breakers and whatever else so things like standard numbers whatever to be fairly easily obtainable and of course things like cable size under whatever you will of course know those because most cases you would have already installed those yourself only a very short time previously so that's it for this time the next one in this series will be on the e IC r or the electrical condition report and that does have on its quad are the same inspection items as that one does plus quite a few more so on that sit one we'll have a look at those in actual real installations and then of course we'll see those in more sort of real-world terms but until next time thanks for watching you
