    I have bought a whirlpool bath and was wondering if anyone can enlighten me
    on the electrical installation requirements for this in the UK.

    not for the UK but I can for the US

    NEC requirements for spas

    GFCI protection is required for both cord-and-plug and hard-wired spas
    containing single-phase equipment [680.42, 680.44]. GFCI protection
    isn't required for the outlet that supplies a spa that has integral GFCI
    protection [680.44(A)]

    and of course proper bonding.

    heres a sample pic.

  3. I've just started reading this newsgroup, and my background is an
    electrician in UK. What does GFCI mean? What does a GFCI do?

    My _guess_ is that it is another name for a RCD - a residual current device.
    This measures the difference in current between the live and neutral, and if
    it is over a specific value (30mA difference being the most common product)
    cuts the power. In the UK these are required where there is higher shock
    risk - for power tools in the garden for example.

    Please someone in USA confirm

    Regards,

    Richard

    GFCI ground fault circuit interrupter, It's there to protect people from
    electrical shock
    correct
    It is able to sense a mismatch as small as 4 or 5 milliamps, and it
    can react as quickly as one-thirtieth of a second.
    In the UK these are required where there is higher shock
    same here also within six feet of a kitchen sink, in bathrooms, spas and
    temporay power at construction sites.
