I've been asked to finish a job that was started a few years ago the only problem is when the job was started the 16th edition regs were in place, So the consumer units that were fitted at this time are also only up to 16th edition regs and so some of the circuits have no rcd protection. My idea...

I've got to go to a job tomorrow and and i no that the mcb's being used are Castlec. I'm not sure what make the CU is but does anyone know if there are any other mcb's that are the same design and so will it fit into the same CU?

My mate has asked me to go round his house and see whats wrong with his immersion heater, he said he's changed the thermostat on it but that only lasted a couple of days and now its stopped working again. I haven't done anything with an immersion heater for years and so can't remeber much about...

Apologise if this has been asked before, but i recently ordered some fire rated 12v downlights for the bathroom but when i received them i noticed that there is no in built hood on them like the non bathroom rated ones. Does this mean that i have to add my own hood or, like a technical advice...

I'm at a job where i've been asked to extend same cables, now unfortunatly this must be done under the floor. I know that Junction boxes are now not allowed, and i would use crimps in a choc box, but recently i found out that apprently crimps aren't very good on solid cables and only work well...

I'e recently changed a consumer unit at the requet of a customer. Before doing it i did a insulation resistance test on the circuits and found them to be within the regs. However after i have changed the board i then did a full pir and found the circuits to be in a poor condition i.e. light...

I've recently wired for a CU at a house but then when i went back to the house the builder told me the kitchen plan had changed and that the sink was closer to the CU that i had expected. It is still 1metre from the nearest edge of the sink to the nearest edge of the CU. Is this still allowed?

I've recently been asked to second fix a house that was already first fixed. The switch by the door is a 6 gang switch and on a stone wall, so the owners have asked for the cables to be run in conduit down the wall. Is it possible then to put 3 x 1.5mm twin and earth cables and a 1.0 mm 3 core...
