    This may be one for the older members on here.
    Got chatting with a mate about a general supplies to showers.
    At the moment you just supply the correct size cable, (usually 10mm for a new circuit) to a shower.
    Was there ever a requirement/regulation to add an additional earth cable along with the power cable? Thinking old regs...

    In the distant past I believe there was a need to add an separate earth cable, don't know the reg number or even if there was one,

    Sounds like the 16th to me when equipotential bonding went a bit mental.

    Neither am I. I'm just curious about it.
    It sounds like it may have been a thing when the domestic people had to earth everything metal in the house...

    I think so... But was it a reg or best practice thing.

    So was @essex@essex correct in that in that it may have been in the 16th?

    Only time I have ever seen additional green/yellow cables in shower circuits it has been supplementary bonding.

    Still required if certain conditions are not met ?

    Not a separate earth as such in the 16th as I remember , but if the supply pipe was copper (conductive) it would be part of the equipotential bonding , as would all the other extraneous metal parts , including the radiator.
    There is still a requirement in the latest regs unless certain conditions are met.

    In the 16th we had a 4mm earth cable connecting to all earth terminals of the circuits serving the location in a bathroom such as the shower then to the light and then down to the extraneous pipe work under the basin, radiator etc
    Looked Gorgeous darling!

    Then additional protection by an rcd made my life so much easier.

    I think it was the 15th when they bonded every piece of metal they could find but I’m far too young to have ever been involved with anything earlier than the 16th:cool:

    Westy is your 15th edition guru on here , still reads the books I think

    Could be that the T&E had too small a CPC, so required Supplementary bonding for the Zs.
    Not aware of any requirement for two CPCs.
