    Domestic RCBO trips different RCBO

    I've just change a CU and installed RCBO's. There is a 32a SP RCBO suppling a ring final circuit. There is a 6a SP RCBO radial lighting circuit. When the 6a radial circuit is energised the 32a RCBO trips. With the 6a dead the 32a stays in. I expected to find a shared neutral but there is no...

    Altered ring main, now a DIFFERENT circuit is not working?

    I’ve just altered a ring main by taking 1 leg out of the board and taking it to a spur (then taking a leg back), to add a socket in.

    Downlights and the different varieties..

    I was with a customer today discussing installing new downlights. I can't quite see the point in installing the really expensive ones as opposed to the cheaper ones. I don't mean the silly cheap ones on ebay that will just fall apart, but for example... Lap fixed LED from screwfix £7 approx...

    The same written paragraph in different sections.

    Hello, I'm going through my 18th edition regs book and discovered two paragraphs that are identically the same. It is regulation 422.3.1 and 422.4.2. is this deliberate because it matters in both section. I brought this book from IET itself.

    Different reading when using continuity and IR?

    This is one of those slightly embarrassing questions that I feel I should know the answer to. I can feel the answer lurking under my skin but it's just not surfacing and needs a push! Pre-work visit for a CU change. There was 65K Ω resistance between N-E on the continuity setting, however when...

    I am adding a fuse box to a campervan to run lights etc off the leisure battery. The existing circuits are fused at 15 amps so I am using 21a cable. But the spade connectors I have are rated at 15a? I thought all spade connectors were the same as most don't give a rating? Will these do or will...

    Air Horn problem, different tones

    The air horn I have fitted sounds great when wires are put across a 12v battery, since it has been fitted to the vehicle it sounds high pitched compared to the deep tone it should have. The deep tone can be obtained (but not always) if I flas the head lights at the same time a operating the...

    Working Out Spotlight Spacings
