    Isolate circuit but trips fuse board

    Hi Weird problem. I’m replacing plug sockets. I isolate the circuit for the particular sockets at the fuse board so it is safe to swap out. All good. Suddenly the RCCB for all sockets - not just the circuit of the sockets I have isolated - trips. Why is this happening? The RCCB doesn’t trip...

    Tenant reported that his fuse box caught fire. I found this stove circuit pullout. This unit was built in the 60s wired in aluminum but I found no corrosion and no indication of foil or other foreign material in the box.. The fuses are Bussman NON-35 Amp. Probably the original fuse from the...

    Difference between FSU and 3 pin plug, both with 5 amp fuse for LED downlights?

    Is there an obvious reason why I can't just fit a plug onto my LED soffit downlights, fitted with a 5amp fuse and plug it into a socket rather than install a 5amp fsu? I'm fine with the plug being permanently plugged in as the socket gets no use anyhow. TIA

    Regular blowing of 13a fuse.

    New supply to garage. DNO have not fitted fuse.

    My customer has had a completely new supply installed to his garage. The DNO has not put a fuse in the cut out though. I'm guessing he needs to contact the DNO to discuss? I realise it would be very easy to pop a fuse in, but apart from this not being allowed, I also wouldn't know the size of...

    20kA ipf on 15A 3036 fuse

    Hello, I changed a socket over earlier and tested the circuit after. The fault current was 20kA, Am I right in thinking I only need to consider the breaking capacity of the service fuse that's likely to be 80kA? I'm struggling to find any reference material.

    Does 1 Amp make that big of a difference in glass fuses?

    Hello, I have a Chinese 90w laser engraver, and recently the power supply went out. While operating, I heard a pop, and when I disassembled, I found one of the transistors had shorted with a black mark. I have since replaced this power supply, and replaced the fuse that is located in the...
