    supplementary bonding

    we are allowed to omit supplementary bonding on the 3 conditions (rcd, disconnection times and main bonding adequate ) if we have a plastic insert we may omit main bonding on water for example. would supplementary bonding have to be added as it no longer has main bonding ?

    RCD and bonding for pools/saunas

    Out on site and somehow all the books have walked out the van! Could someone do me a favour and look in the BGB and tell me if bonding is exempted if RCD is in place, and whether the RCD needs to be 2p or not? Not even sure what there may be to bond yet! Cheers muchly. R.

    no evidence of supplementary bonding to pipe work

    I went and did a visual inspection on a flat. No Rcd protection present. 10 mm earth to water and gas was connected. No sign of supplementary bonding. So i did a long lead test and found that all pipe work in kitchen and bathroom was below 0.05 Ω. Does this mean no supplementary bonding is...

    No RCD protection...

    If I was to install a new shower for someone using an rcbo as theres no rcd protection would this be ok? What i mean is am I ok as long as the circuit I have installed is protected? Or would it be up to me to make sure there was protection for the other circuits?
