    "voltage relay" instead of RCD ?

    So I'm getting my flat in Kyiv (don't ask...) done up. I'm using quite experienced builders who have their own tradesmen. Now when it came to electrics I had two main questions: 1/ sizes of the cables on each circuit and 2/ Would there be at least one RCD in use ? For part 2, he came back and...

    Does fuse board or switches contain asbestos?

    Hello, looking to get home electrics upgraded and get a new fuse box. A neighbour mentioned that their house had a main switch on the fuse board that was encased with asbestos and I’m wondering whether we will be in the same position with our old fuse box. Does anyone have any idea based on the...

    TT - Consumer Tails Protection

    Quick question, Do TT earthing systems consumer tails require RCD protection? I believe they do, but I rarely see them on short tails? Does it only apply when the tails are over three meter? Thanks for any help electrical masters 🙏

    RCD or RCBO consumer unit

    Hi . I normally do industrial electric work. Usually on Schneider and Merlin Gerin boards I am looking at fitting a new consumer unit at home and seem to be getting two versions of which board would suit best. Either a dule RCD board with MCBs Or A board with all RCBOs. Which would be best...

    RCD tripping when planer turned on?

    Hi, I recently bought a new planer. When I switch it on the RCD in the garage board trips. The machine doesn't try to start, the power trips as soon as the ON button is pressed. It has a 16 amp plug. I plugged it into an existing 16 amp outlet that I use with my welder. The planers info plate...

    Does SWA need RCD on a TT?

    I know the answer, at least I think I do as I am now questioning myself! It's just I've seen a few jobs recently where the electrician (or who ever did the job) did not give any fault protection to the armoured cable, so I am wondering if I am missing something? The most recent example from...

    What exactly happens during an RCD test? (Methods 1 & 2)

    Sorry this is a bit of a long read but I’d be extremely grateful if someone can help me understand RCDs and testing methods of them. I know RCD test applies a fault current but in what way? I understand how continuity/IR and the other test work so it helps me know what to do, what’s going on...

    Meter box RCD tripping

    The meter box RCD for my power outlets in my home trips at random times, approximately every 13 hours. Have used a portable RCD box to test every appliance plugged into outlets but the portable RCD doesn’t trip. Any ideas? Faulty outlet? Faulty RCD ( it’s 25-30 years old)? No other circuit...

    Has anyone found the rcd tripping even when on no trip on a new circuit. Cannot find a fault on the circuit. Tried on another socket circuit in the premises & that tripped as well.

    Zanussi electrical oven started tripping the RCD

    Hi All, I am new here. I searched the forum regarding this issue and most professional advice was that the heating element should be at fault. I am a DIY person and I would not have a problem replacing it myself, only that a new heating element costs £45 on Zanussi.co.uk and I would not want...

    RCD tripping only when high draw device and lighting ring is on.

    Hi. Wondering if anyone had any idea what might be happening. Last night I damaged a pendant light fitting by accident, not enough to stop it working. However later in the evening when my car charger started at 11:30PM the whole house RCD tripped. I only thought back to the light accident as...

    Isolating switch needed?

    Hi, I have an underfloor heating system in a room (just less than 2kW). It works absolutely beautifully but an electrician who came to swap a socket in that room said that it looked like a ‘lazy install’. He was unprofessional and a rip-off - so I want to get someone else to check it - but I...
