    New consumer unit but lighting has no earth

    I've been asked to fit a new consumer unit in an old property. One issue that I have found straight away is that the lighting would seem to have no cpc (old 2 wire cables). Ideally I would advise to have the lighting circuit rewired but the 1st floor of the property has a flat roof with no...

    Recommendations for a combined MCCB/ELCB unit

    I'm on the lookout for an adjustable combined MCCB/ELCB 125A size unit to act as upstream protection for general distribution. Schneider do this one except it's on long lead time. I've had a look at Eaton / MG and a couple of others and can't seem to find much. I know I could split them into...

    Consumer Unit Fire Protection

    The sparky I am working with always mounts consumer units on a fire retardant board. I am in two minds as to whether this is necessary. Regulation 421.1.201 states that the enclosure must be manufactured from non-combustible material but doesn't mention what it should be mounted on. Can anyone...

    continuity tester and proving unit also required?

    Hi. We have a circuit where some of the sockets have a dangerously high earth loop impedance. This was identified by a professional electrician. I was thinking of rewiring this, as a DIY project. For safety, I want to ensure the replacement is done to spec. Buying a multifunction tester seems...

    Duplex consumer unit

    Hi All, A family member is looking to having their consumer unit change to a larger one with Rcbo's. I have seen a 36 way wylex board WYLNMDRS36SSLHA however it is a dual rcd. Can the rcd's be removed and board used solely with Rcbo's? I told them I would try to find out for them. Many thanks

    Weird Electrium Consumer Unit B4471/2?

    Hi, I am having weird behaviour from my flat's electrics which I think will need an electrician. The flat is empty whilst it is being redecorated and there is nothing plugged in. With no load the RCD trips some days and will not reset but other times is fine. I have discovered that if I switch...

    Recommendations for a Voltage Indicator and Proving Unit

    I’m looking to save for a Safe Isolation Kit, we done the Safe Isolation procedure in College using a Martindale Kit. But would anyone have any recommendations for a kit to buy? The Martindale was good but I’ve seen a few other manufacturers that seem to offer more features but are they worth it?
