    Consumer Unit isolator with RCD

    I have an old CU with BS3036 rewireable fuses. I'm having the board upgraded soon but in the meantime I'd like to add RCD protection. Can anyone tell me where I can find a consumer unit isolation switch with RCD built in - to fit between the meter and the CU?

    4pole isolator on single phase

    Hi, I have been asked to fit a 32a isolator ready for an air con unit and picked one up from screwfix. Unfortunately the one I have is a 4 pole, can this still be used with 6mm t&e or do I need to replace it with a 2 pole. If it can be used do I just use terminals L1 & T2 Thanks

    Boiler Isolator

    Hi All, I've just had a new condition report. He's given C2 for no fan isolator which I don't agree with. He also given C2 for the boiler being on a plug/socket rather than a DP switch.
