CJR ELECTRICAL Installing 18th edition compliant consumer unit.

[@J0nny61]

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

On the grommet strip - recently got a great tip from another spark I was working with. Take a bit of sheath you've stripped off a cable, split it down the edge, and use that.

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!

[@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.

[@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.

I'm studying level 1 installations and I've been through dozens of youtube channels to help with my learning and you are by far the best source. Keep up the good work and I can't wait to be competing against you for work 🤣

[@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

[@mrclive5]

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

[@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.

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

[@normanboyes4983]

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.😉

[@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 😂😂😂

[@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).

[@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

[@jamielightfoot8167]

on them hager boards are you finding the Spade connections for the SPD that terminate on the load side of the main switch to be loose ? even after i terminate correctly they literally just pull straight out ? I rang up technical and they said they had a "issue" with the Spade crimps not being the correct size for the main switch Terminals. even though its Low current, I wouldn't like to leave a property knowing a connection is loose.

[@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.

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. :)

You said something about getting giving that fuse board to someone. It would be great if I could have it for my students at college for an example

[@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.

[@gritnix]

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.

Finally we can cut the seal guilt free! Do you have a tool to reseal it? Would love a recommendation.

[@Hammy135]

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?

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.

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.

18th amendment 1 2019 another label "Check SPD quarterly", 18th amendment 2 2020 " check SPD every 6 months" sigh :(

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!!

SPDs are a nice idea that i am sure will become standard, a better upgarde in my opinion would be to make RCBOs mandatory rather than split loads which arguably don't comply due to the disruption they cause in the event of a fault and the RCD not resetting.

Interesting I have never tested N-R2 before, I guess now with AFDDs that is a good idea.

I have been fitting Hager SPD board's since January now, you can't get much better than them. But got to say nice looking board and all those labels on it? I put mine underneath the flap it's not like anyone reads them anyway, May aswel make it look nice. Good vid bud!

[@ashmanelectricalservices4318]

Labelling giving instruction should be visible... RCD test label, Next inspection & test label etc. Everything else can be hidden underneath the cover.

[@serenetysteel7007]

@@ashmanelectricalservices4318 It will be visible when you lift the flap, which is what you would have to do if you need to do anything on the board ; )

[@ashmanelectricalservices4318]

@@serenetysteel7007 No homeowner is ever gonna lift the cover to check how frequently to test the RCD or when the next test is due, at least if it's clearly visible, half the works already done.

[@serenetysteel7007]

@@ashmanelectricalservices4318 I have met only 1 homeowner that has ever tested their RCD out of hundreds, despite an RCD test quarterly label being present in full view of the world. Likewise for commercial customers who have never tested an RCBO or RCD full full labeling being present

[@serenetysteel7007]

Plus you have to lift the lid to check the RCD!
