I'm having to take a look at my 3 phase supply due to the insurance co being normal a_ _ holes that they are. Naturally they are demanding certification of said wiring.
Upon getting one quote from an electrician, which incidentally nearly cut my life very short indeed, I had to seriously question what the hell he was going to do for that amount of money.
My distribution board is an old crabtree with C50 mcb's. I automatically assumed this would have to be replaced due to its age. A bit further investigation it seems this may not be the case at all, providing the mcb's meet the trip times they should meet. If the mcb's meet the criteria, the way im seeing this is the only thing i need to actually do is add 4 pole RCD before the incomer. Could one of you kind gents please confirm.
I installed the whole 3 phase in the building about 8 years ago now. What i did not do was install a neutral throughout system beyond the dist board. Purely for the fact that nothing i have 3 phase needs a neutral and is not wired for it from the factory, what is the score do i need to have a neutral system in place to meet regulations, even though its of no use at all.
Many thanks in advance.
Kind regards,
Scott
