Ideas welcome rcbo replacement

[Gazthesparky]

So I have a job coming up, a customer wants most of the socket fronts replacing in there house.

The board is an old GET board with MCBs not an RCD in sight.

As GET are discontinued I can not get RCBOs to swap out the MCBs

So I have a couple of proteus RCBOs although I hate them they seem to be the same size as the GET gear so Im hoping they fit properly. I don’t like mixing manufacturers but I don’t have a choice.

Failing they don’t fit I’m going to fit a small dB by the side of the existing one leave the MCBs in place and wire the RCBOs off them and then to the circuits.

This is a lot of work but I cannot see another way around it.

I don’t want to put a front end RCD in the sub board as this means all the sockets will be on the one RCD meaning you loose everything when a fault arises

I have suggested a board swap but they had the board change 5 or 6 years ago so don’t want to go down that route.

So open to any other creative ideas instead of having to pull all 3 ring circuits into a new board.

Cheers

vis a vis Best Practice Guide 1.

As a Consumer I'd have lost interest in that leaflet at page 4, and there's another 12 pages to go?

Might be a good idea to read the whole document in your case then Mate, as a Consumer / maintainer.

Did GET rcbos actually exist in the first place?

Yes according to my old 2004 catalogue but were two module but they could have been available after that in one module as we have as standard today not sure what consumer unit fitted by GET.

Personally if Proteus RCBO's fit properly then that's what I'd fit. Been in this situation plenty of times and as long as a different make fits properly it's never going to be a problem regardless of manufacturers instructions, because standard RCBO's are manufactured to the same specs regardless of make.
I really cant see why other options are being discussed.The idea of adding an up front RCD is quite frankly daft.

Probably because I have the time, and don't rely on working any more, but an idea, not just for you JK, but all potential CU changes.
It appears to me that most homeowners just don't know the rules and regulations, regarding changing CU.
Now me in my infinite wisdom wondered if it might not be a good idea, that when quoting for a CU change, you include in your package a copy of the Electrical Safety council's Best Practice Guide for CU changes and in your letter / quotation advise the client to read and inwardly digest. Just a thought. It's what I what I would do if I was still working, may save all the accusations of probing for extra work, what do you think? a good idea, or am I talking out of my backside?

No and they are F.O.C.

I'm playing devils advocate here BUT where does the BBB specifically state that replacing socket fronts means the circuit HAS to comply with the latest regs..............

That's what the other 3 "sparks" would say

Given there are at least 4 people quoting, then simply quote for the replacement CU along with the replacement sockets and forget about it.......

It doesn't, but doesn't define alteration or addition either.

I agree with your last paragraph though.

Yet another failure from the IET

I did try and tell them this at Elex yesterday ......... the chap I was talking to seemed surprised about their inability to write clear and coherent regulations ................

Suppose that's why they do those on site guides, for us lesser mortals.

Like they are clearer ............. NOT

Got more pictures & diagrams though.

Am I missing something? Are you adding additional sockets in? Why do you want/need RCD protection if you are swapping like for like you aren’t altering the design of the circuit if your just swapping faceplates.

GET was taken over by Schneider in 2006.
I would advise contacting Schneider to enquire whether their RCBOs are compatible with GET CUs.
