    Can RCD/RCBO trip if no cpc is installed?

    Good morning, :) I saw lighting circuits done with 2-core cable (red-black) with no earthing conductor. I was wondering in a case of an earth fault is the RCD/RCBO going to trip? I think if a metal switch or a chandelier becomes live, the RCD/RCBO won't trip due to the missing cpc! But is it...

    This has been posted about a lot but I wanted to ask a really stupid question. I can only run 4mm single g/y to each metal fitting from the board which is dual rcd 30ma. I cannot touch the drops, stipulated by the landlord. Is it acceptable to issue a mwc for this, write a safety letter and...

    Board change with no cpc on lighting

    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.
