My last 'non Amd 3' CU Install.

Dave OCD · Dec 21, 2015

Put this in today, I hope it doesn't burst into flames.:tongue3: Didn't have the time to faff about and get the cabling 'perfect' as I had so much to do today but I think it's ok. With the BG boards I generally 're number' the earth bar as to me it's illogical having the CPCs running in the opposite order of the neutrals,I'll miss the insulated CUs. Sorry about the
poor photo.

So how is running the earth conductor in same hole going to stop this rise in temp.? I was always under impresion eddy currents were concern in line and N conductors in >200amp installs. Please copy n paste the reg on here fir those of us who dont have a big book to hand

Blimey ,

One minute giving me brutal criticism and going well overboard about a perfectly good,safe and totally compliant installation and now you want to disregard certain regulations. :juggle2:

Up to 5seconds if you mean the duration of the fault

Many many years of you mean how long this regulation jas existed

Reg No ?

telectrix · Dec 27, 2015

you can put the cpc in a separate hole as long as it's a square hole. by the time that eddy has negotiated the corners, the fault will have cleared. :behead:

The old thread that lasted 155 posts on this subject was called Advice on regulation 521.5.1

My browser wont let me copy and paste the link but type it in to the search bar.

My wrong just read the Reg came in halfway through a thread should of read the whole thread

Let's see how many errors we can spot in one of my boards. This is a second hand board which I've fitted in the warehouse for the test bench and work bench.

I can put up a few pictures of a dimmer I fitted in a rush just before Christmas too if you want?

we can all agree on the fact the reg says we should.

ive never used a wiska gland and i have no intention of using one when a bush and lockring will work just fine.

the earth is too far away in that pic above for the eddy currents to affect it though isnt it?

Looks pretty good to me, maybe brown, black and grey markers down the centre to correspond and clarify the old to new line colours would look the part though ?

telectrix · Dec 27, 2015

or just make everything grey. at least you could distinguish red/yellow/blue in poor light.

Maybe they would, bit in my highly technical opinion i say 'bugger that for a lark'
It'll only ever be one of us working on it as the whole workbench will be taken down amd moved if we ever do

Someone said about the difficulty of making a really neat job when reconnecting older wiring into a new CU,here's a 'before and after' from a few months ago I know there's a connector in there,one of the CPCs was too short.

Edit - The interesting think about this was that circuits 2 and 3 in the old Wylex [from the right] were the two ends of the same RFC, it had been like that for 45 years !

You've stripped the sheath on the blue tail 1/2" too far back.
Rip it all out and start again.:33:

Some very impressive work there fellas, has anyone who's posted installs got any of the board partially installed ?
Are boards with all the cables from below slightly harder to get hyper neat ?
