    Low insulation resistance and tripping circuit breaker

    I've just done an insulation resistance test between line and earth and got 0.0 Mohms for most circuits. Obviously this is an F1, but what I don't understand is why the CB doesn't trip. Is the answer that the resolution on my tester isn't high enough? So I could for example have 0.049Mohms and...

    Blowing breaker

    I have a very small circuit in my house. Probably 8 outlets 6 lights. The breaker for this circuit has a direct short somewhere. It didn't start this way.

    Tripping contact breaker

    I have a contact breaker that trips off randomly. Sometimes it's two or three times a week and at other times it can go six weeks or more without tripping. It doesn't seem to be associated with switching any lights or appliances on or off and I'm worried it could trip off when we're away on...

    3 pole breaker query

    I know it needs to be replaced, but what actually causes a 3 pole breaker to suddenly stop being able to stay in the on position please, and that's even without it connected to anything (i.e. the switch mechanism makes the correct sounding click when push up, but immediately springs down)????

    Replacing pool pump: wiring from breaker box through timer to pump acting strange.

    New member, DIY homeowner here. I bought a new in-ground 1HP 120v Harris pool pump (online) and had it installed by my pool maintenance company.

    UK Thermal breaker to derate circuit?

    Hi chaps and chapettes, I have a buried 6mm SWA 32a radial circuit powering a single 32a commando/ceeform, i'm looking to add a 16a ceeform for convenience. Can I use a thermal-magnetic breaker to derate to 16a. There isn't space for a 2 way CU so would this be my best option? Thanks.
