Electric Shower isolator ?

aligarjon

Hi guys.

I have just done an EICR on a rental. They have relatively recently had a shower installed (brown/blue cable) with no local isolator fitted. The CU is quite old so the mcb's can't be locked off and neither can the up front rcd. Does a C3 sound right or no code just a mention. I have looked at a couple of Mira installation manuals for reference and they state recommended isolation switch rather than requires so as far as i can see not a manufacturers instruction either.

    Yes, but see note 4.

    I'm pretty sure that regs- wise it can, and dedicated isolators one per cooker/fan.shower etc are not strictly required, and they could all be the same  set of contacts so long as that main switch is sensibly accessible - however it may be really inconvenient to turn off a large area to perform a small task.

    The regs set a minimum technical  standard, not a best practice  target to aim for.

    An EICR fail really should be able to be cross-referred to BS7671. A lack of local isolation. I  think, would seem to be a design weakness perhaps worth commenting as making switching off unnecessarily disruptive to other users, but not a C3 unless other things are wrong as well because of it.
