I've been in the trade for 42 years and for the last 15 years in electrical compliance and Electrical Project Management. I'm also a full member of the IET. I think your knowledge and understanding of domestic work and the 18th edition is a credit to yourself and the tutors who have trained you. I also understand you're competing against people that will under cut you time after time. I wish you the very best of luck and I'm sure you'll do well. Great video.

[@mb-electricalservices]

Love hearing my fellow electricians who have just passed the 18th as they're suddenly "reborn" with all this knowledge they never knew before. :D

[@danielbrydon3869]

18th edition states that consumer units must be made of non combustible materials. It doesn't state they need to be fire proof or sealed. So long as the IP rating is maintained that is all that is required.

[@Cjrelectrical]

Yes your correct but why not break the mould and go above and beyond.

[@Microwebb]

Correct! I don't understand why people insist on sealing every hole in a consumer unit. Especially when the consumer unit has plastic MCBs and RCDs.

[@zjzozn]

Fire barrier?

[@tomorichard]

I can understand in this case as there is a gaping hole into a stud work wall (fire propagating) but as stated it’s not strictly needed.

I'm by no means an electrician, I'm in Canada, so we have 120v, I find what you do absolutely fascinating. It's neat to see how different your breaker boxes are (that's what we call em.. or I do anyway). Switches on plugs... a foreign concept to me!

[@davidpope8133]

IMO the trouble with SPDs right now is they could fail the very next day after you install them, nothing beeps, no circuits trip or are disconnected, there is only a tiny red non illuminated flag in a small window behind the cover and as we all know homeowners don't lift the flap on the board unless something trips! Customer would never know they were not protected for years until the next inspection, and when you do see one has failed and go to buy the "cartridge" most manufactures don't actually sell the cartridge as a separate item, you have to buy the whole SPD unit again lol. Maybe they need to make something like an audible signal on fail same as when smoke detector batteries run down.

[@DKNY707]

Totally agree

[@MrJustbrowsing12345]

[@allanapel123]

Thanks for answering our simple question following a couple of C2's on recent EICR. Our sparks gave us one price to continue with the existing plastic CU or and a higher one to install metal. Your video explained that very nicely. Thankyou, enjoyable, informative watching. You guys are artists.

[@mrclive5]

I think you're reading through the dimmer module, hence the high Ohm measurement.

[@philip426]

One problem with 18th edition boards is that you will never know if the SPD blows. A solid metal lid on the CU, how many clients will look under the lid unless the power goes off especially if the board is in the garage or under the stairs behind the Dyson.

[@ashmanelectricalservices4318]

The customer will have to check it the same time as they do the six monthly RCD test 😂😂😂

yeah thats something i do when i remember, what gets me is, on the MK boards there are 3 large holes in the back, yet only enough grommet strip for two is provided with a short piece left over why?

[@arniewheeler4673]

What temperature can super glue withstand? The flash point of super glue is around 80°C.. Dried superglue is fairly resistant to heat but it's strength will be reduced. Typical outdoor temperatures will pose no problems (by typical I mean up to 100-110degrees F).

[@Brando1667]

Very thorough indeed just like in all your previous videos. It’s good to know there are tradesmen like you out there. It’s just knowing which ones they are when we need one.

[@ashmanelectricalservices4318]

R1+R2 isn't enough to prove polarity as the line and cpc could be reversed at an accessory or outlet, R1+R2 and R1+Rn prove everything is where it should be.

I liked the reference to bigclive near the beginning. He must get some interesting packages in the post every week.

[@acelectricalsecurity]

Its ok these guys that teach the regs saying you need to do x,y and z, but in the real world it's not always possible, and we do a lot of crap we shouldn't be doing anyway. With spd protection, blame the IET, if they said it must be fitted fair enough, but as usual they don't, so it won't get fitted most of the time, and in 30 years of doing this job I have come across it once on a neighbour's house and don't get me started on torque settings.

[@asef698]

Before changing any consumer unit I run IR tests on everything, won't fit one unless they all pass, or client agrees to fix faults etc. Changed a board in my earlier years only to find everything tripping with the old rubber insulation being perished. Only made that mistake once. Enjoyed the video, cheers pal.

[@petertallowin6406]

I always recommend a prework survey before a board change consisting of a full test on the installation. Speeds up a board change no end. RCBO boards as standard.

[@ashmanelectricalservices4318]

A lot of customers aren't willing to pay for an EICR before a consumer unit upgrade.

[@petertallowin6406]

@@ashmanelectricalservices4318 by full system test I mean an individual test on each circuit. A few hours testing agreed with customer before hand. A simple r1r2, Ir, r2. Not as full on as an eicr and doesn't take long in the grand scheme of things and helps highlight any issues. Depending on the outcome of those tests an eicr may well be required. :)

I enjoy your videos and you clearly love your work.👍 I do smile when I hear instructors scare stories of do this or don’t do that or you will end up in court. Yes maybe you should but how many electricians or pseudo electricians have appeared in court for negligence or non compliance with Regs? Nice move by the National Grid delegating responsibility for power surges to the consumer.😉

[@motomartinski5672]

Good videos. Bring back memories of 14 yrs of self employment. I felt for you with that N-CPC issue. Been there (numerous times) when on the tools, even with my own fresh installation - because of long-standing defects in old appliances, particularly cooking appliances and lighting control eqpt. One customer had a nightmare of tripping after the power co upgraded (actually enabled) the main earthing. Tough to explain and tough to rip up kitchen floor and raggle nice walls to replace circuit segments! Just a couple points that might make you think / bear in mind about an important distinction with responsibility / liability. You gave a bit of advice to other sparks re if not fitting a SPD - in order to protect themself from a claim in the uncommon event of a surge severe enough to damage appliances - they ought to get a record of the customer saying that they understand what a SPD is for... and they choose not to have one fitted? My understanding (though perhaps I'm interpreting regs incorrectly) is that from 2019 that would in fact do little to absolve the installer of liability - because although fitting of SPDs is advised, rather than mandated, _for compliance_ the installer would then have to produce a report justifying _in a technical sense_ why a SPD wasn't necessary, including a detailed assessment of various aspects of the incoming supply (characteristics, length, configuration in supply-side network etc), much of which would require formal queries to the power provider... and hence not fitting a SPD would not be a route that most sparks would want to go down now. - regardless of what the customer's written instructions were... Then there's the temp fix thing. Been in that position as well - many times... and yes I may have done something like temporarily put a HR (not flame resistant) flex somewhat close to a possible source of flame. Eventually though I became less pliable / far more cautious in offering 'easy' temp solutions ('temp' often ended up long term once the spark has gone) You see it doesn't matter that you advise someone to do or not to do something unusual just temporarily. In the final analysis if the safety of a piece of work hinges on (for instance) a customer not using a gas hob ring... and somehow ensuring that any/all other possible users know about and remember to comply with that; then technically, whether for 5 days, 5 months, or 5 hrs, it is not acceptably safe. And _legally_ you are not safe. All would change if things went pear shaped and lawyers or HSE or plod got involved - and what the customer said or understood or agreed with (even if you video'd their relieved agreement), would be secondary to the central issue of technical compliance, of which you are held to be the competent party - not the customer. \_(シ)_/ Take care and keep up the vids.

[@andrewjohnson2668]

Have you never tested before continuity of main equipotential bonding ? Quite an important test even before 18th. Also high ohm reading more than likely the resistance through the dimmer. Can also get accessories to fit into the huge back knockouts in Hager dbs. Other than that not bad bud

[@davidsaunders8590]

Great video! I love the Hager boards, really good quality. Hager do have moulded grommets (shown on the leaflet I got in the last Hager I fitted). It’s nice that you get the grommet for the tails with it and at least they supply a bit of strip that’s way better than nothing. Great fault finding and testing demo, fair play

[@DaC-lt5mk]

I was taught on my 18th that if the price of installing an spd is higher than the price of the electronics likely to be damaged by a Serge. Sounds iffy when he told us but that was he said

[@robswingler]

DaC27 96 I’d say if the customer doesn’t think the extra £40-80 for spd isnt worth protecting their electronically equipment then note it on cert and don’t worry about it . You can’t know the total price of electronically equipment in someone’s property.

[@Raysnature]

@@robswingler It's not the cost of the SPD that's the issue but the cost of the spark to come out and do it. Really needs to be a consumer replaceable item assuming one is needed at all.

If you're reading this comment in 2030+ please let me know if almost every house has a CU with an expired and ignored SPD ;)

[@raychambers3646]

@Steve Mclean surely the onus is the supply company to ensure a supply fit for purpose, if it blows your kit it's not the sparks fault, just another way to wriggle out of paying out.

[@simongreenidge6454]

You won't lose power to the house - the SPD will quietly stop protecting against spikes. The sensible option (Ha! Ha!) would be for the manufacturers to come up with a standard user-serviceable SPD module; the Sparky gets paid for the CU installation, then the householder monitors the indicator - when that shows red they pull the worn out one and replace with new. Many punters won't bother of course, but having to call an electrician to replace? Almost no one is going to do that.

[@davemorgan7695]

[@colinhaggett]

Steve Mclean That’s the problem, they only work once and no one will ever check them. Has there been a lot of problems with surges in the uk?

[@raychambers3646]

@Steve Mclean it's not only lighting that causes surges the power companies have been responsible in the past, I remember a case locally when a joint in the road was wrongly connected 415 volts instead of 230v routed to houses ,lots of bangs!!

[@actierney]

You should take a look at the Fusebox 18th rcbo spd consumer units. Its all I fit now. Technically a dual rcd board doesn't comply with reg 314.2 A single circuit failure should not affect another circuit.

Artisan Electrics I’ve pulled plenty and resealed them, got some seals from eBay and crimped them with snips. the guys i did my apprenticeship with, used to cut and pull these main fuses without batting an eyelid so it was normal to me. But I’ve read so many horror stories online recently about the carriers coming away and them blowing up and what not, it’s made me think twice. I know if the board is isolated and you carry out the right procedures then there shouldn’t be an issue. How many of you out there make sure you megger the tails before you put fuse back in incase (however unlikely) live has snagged on the metal board?

[@totherarf]

Yes they are available in every tool supply store! They go under the name Snips or Sidecutters ;0)

[@Rosscoff2000]

Re measuring resistance on a radial from neutral to cpc, if you short L & N at the far end to do R1+R2, can't you then do one insulation resistance test from L+N to cpc which will show you any leak from either conductor. Obviously if you get a fail you can remove the short and investigate whether the fault is on L or N.

[@ashmanelectricalservices4318]

I don't think it's written down in any electrical documentation or manufacturers instruction as it's a call on the installers part. If the terminal is big enough to accommodate a wire being doubled over, then it should be, it's more of a best working practice than anything else.

[@WhiteRoseShooting]

You can not cut seals and pull fuses, everything from the service head to the meter is DNO property, nowhere in bs7671 does it say you can pull fuses.

I never said it says in BS7671 you can pull fuses or cut seals. What I did say is the 18th edition lecturer who is also an inspector did say rather than working live as stated in the HASAWA. Yes we can pull the fuse for safety. But please if in doubt ring up your local DNO and have them fit an isolator for you.

[@WhiteRoseShooting]

CJR ELECTRICAL so you’ve done a video telling all your subscribers you can pull fuses because a random lecturer told you that you could, the fuses are sealed for a reason and only DNO or meter engineers can cut the seal or re seal them, electricians can not pull fuses. I know this because I used to be a meter engineer and you need a completely separate qualification and to be registered to cut seals, pull fuses, and re seal them. So people who have watched this now think it’s acceptable to do things that they shouldn’t be doing.

Dave Morgan AFDD are only a recommendation, not mandatory..............yet! SPDs, now don't quote me on this, if your area by some sort of calculation, which I'm sure someone has done on KZbin, David Savery springs to mind, is in, above or below a certain threshold (not sure if I'm honest) you may not need to fit an SPD. But being able to get an accurate calculation for this, because of variables and lack of information to carry out an accurate calculation proved extremely difficult. Guess it's more of a case of fitting one to protect your arse.

@@craigemmott4976 Yes I think your right Craig, risk factors etc come into it and which type 1 or type 2 depending on out comes. I think Gaz did a video from GSH too.

I hope that you did not reuse the same plug top for the temporary supply to the oven as it was an old one with the uninsulated live and neutral pins.

[@Woodkin007]

Just a quick one How is 0.33 ohms higher resistance than of 0.55 ohms?

[@JayTheSparky]

I always say the same about the grommet strip mate! I don’t get why they can’t give you a grommet or something similar to the whiska grommets to use for back entry! I always feel it’s the only thing that let Hager down really as we also fit these as standard.

[@paulcraft4630]

I've tried tape, super glue etc, fits great till you lift it on the wall and it pops off, got to the point of leaving it and letting the mastic do the job of stopping the cables rubbing against the metal

[@saab93contdi]

Is that mastic now a reg….

[@mohamedsiadabdille7631]

Hi! I have been watching your video really interested video and I have been learn a lots also I call myself electrician but I am not nearly up there, do you mind if I ask how many years are on this work thanks

[@ronniezzzz]

like the torque screwdriver mate

[@ashmanelectricalservices4318]

Who does the best teardown... John Ward or Big Clive???

[@line10cls]

plugs on hob and cooker no 1/2 insulation on L & N did you change them ?

[@jeffbaldwin4238]

I hope you removed that twin socket for the oven and Hob when you was testing for the oven, because it could of been a faulty socket? Didn’t see it removed in any of the videos? Would be the first thing I’d of done but you didn’t mention it in your video? As I’ve sockets like that hidden away with damp problems etc causing that.

[@Cjrelectrical]

Thanks for the comment unfortunately I don’t get to fill every think otherwise my videos would be six hours Long. I did however disconnect the socket and retest to find the cable was faulty

[@thedavesofourlives1]

strange having the consumer unit against the ceiling - in north america the codes say it has to be midway up the wall at "short lady" accessible height.

[@Cjrelectrical]

Yeah we do have a regulation height for a new build install but as this is an existing we have to install where the cable length will allow.

[@marcbiff2192]

Why all of a sudden should voltage spikes be a thing?

[@brixtar]

Beware live vs line, or did you mean live conductors?

[@JBE]

congratulations!! Great video Chris.
