    Could any of you kind people clarify wether an isolator is required for an electric shower installation.
    The manufacturers drawing shows one and quotes b.s. 7671 but I can't find anything in the rest
    As a matter of fact I All ways fit one for safety reasons
    Thank you in advanced

    No requirement in the wiring regs, but good practice and useful to have one in most cases.

    Don't forget to IR the circuit before you install the switch. I usually IR from the board to where the switch is going to be then from the switch to the shower itself.

    Well if the manufacturer recommends one be fitted, you'd be running foul of 134.1.1 and 5.10.3 if you didn't :)

    Why IR test before completing the installation? You’ll only have to do it again once the installation has been completed.

    I've always done it that way to avoid the neon in the switch messing with the results.

    Maybe I'll get it in the neck but if the tests are OK, from board to switch, then from switch onwards to the shower itself then I'm happy. I prefer that to cross linking the L-N and then testing those two to E.

    Ir should be done with All accessories in place and screwed back surely you can do phase neutral to earth to avoid the neon

    At the end of the day, I feel that it's more important that the actual cabling is properly IR'd than the switch. I mean that's the whole point of the test surely?
    Also, whilst L-N to CPC might be acceptable on an EICR (with an agreed limitation) it's not something I'd be happy with on initial verification.
    At least doing it my way, you're going to be 100% sure the circuit hasn't been damaged during installation, and what are the chances you'll bugger it up just by adding the switch back in?
