I understand that RCD protection is a must and RCBO is the best...

    Carrying out a refurb on old panel boards, worried about discrimination.

    I am carrying out a refurbishment job on this old panel board and fitting in a new panel board from Schneider. The current supply to this building is a 100amps BS88-2 Gg (assuming).

    Hi everyone, could someone far more experienced than me explain the issue regarding TT earthing and using metal cased dual rcd boards. My understanding is that the links between rcds within dual consumer units have no protection therefore a board would become live if they became loose and...

    No isolation of Neutral in Single phase boards

    As title. Doing an EICR, have come across a couple of DBs, where the neutral goes straight onto the bar on Single phase boards. Whats your views on this guys?

    Wd40 and fuse boards.... Anybody tried it?

    Had the WD40 out earlier cleaning my fiancees bike up. Saw on the side they suggest it can be sprayed into mcbs on a fuse board. Can't say I have ever thought of that. I know it can be used on contacts but it somehow seems wrong to be spraying a liquid into a fuse board as shown on the can!
