Board change with no cpc on lighting

[Paul117]

Hi all

Been asked to quote for a board change. Had a quick look round the place and discovered lighting circuit has no earth. Where do I stand on this?

Current board is 3036s and will be replacing with rcbos as wiring is quite old. Will also be bonding the gas and water from 4mm to 10mm.

ESC have a best practice guide on this here: Best practice guides : Electrical Safety Council

lighting circuit is ok as long as it doesn't have any class 1 fittings or switches on it reconnect it to new consumer unit and make note on certificate

That's what I think as well, but I notice that the Best Practice Guide is a little more flexible than that if the customer refuses to replace Class I fittings or rewire the circuit / install a protective conductor, maybe a little too flexible?

And don't forget the "warning sticker" too!

God forbid, forgetting yet another warning sticker to go on the CU!! ...lol!!

Oi! Stop slagging off stickers, I've got shares in Electrical stickers and I'm doing very well, thank you very much!!! :smilielol5::biggrinjester::joker:

The sticker/label designers need to make them smaller!

No, Amendment 2 will carry a new requirement that every CU/DB will have a 600mm[SUP]2[/SUP] notice board next to it for sticker affixtion!

Is wiring method is by metal conduit by any chance?

The esc cu guide actually allows you to fit a new consumer unit even with metal unearthed fittings

as long as they are not outside or within reach of any extraneous conductive parts

but you must perform an IR test between the live terminal and the meatallic casing of the fitting i think if memory serves correct?

Oh Dear, here we go again mg_smile:

The ESC is not in a position to allow or forbid anyone to do anything. It is a guide.

Are you sure? What would that prove, other than it was not live when you tested it?

Would recommend if you post somthing like this, that backing it up with a link to the approprate documentation would help.
