I have been asked to price for moving the circuits from an old 'Federal Electric' 3 phase board to a new(er) crabtree one mounted a few metres away.
The main switch is badly melted etc. and they have subsequently lost the red phase (so dumb waiter, etc. ) in a restaurant. I can't get a replacement switch, and the board is in poor condition anyway.
I want to give as low a price as possible as I think I could get more work off the owner. The more recent board fitted further along has plenty of spare ways. The circuits in the old board include some 3 phase cooking appliances (building all electric) numerous socket circuits, hand dryers etc.
The old federal electric board has had a plasterboard wall built around the sides and top, with other DBs, FA panel, sec. alarm panel etc. mounted on so replacing this board isn't an option- there is NO space and no chance of getting it out. My idea was to remove all the guts inside and fit some DIN rails with connectors and extend all cables out of the bottom and over to the next DB, then drill some holes and bolt the lid of the old DB shut.
What is the minimum amount of testing/certification to provide & would RCBOs be required -at all- . (Unrelated but I was surprised to find out from NAPIT that I didn't need to RCD protect some modified socket circuits in some offices- RCD rule of cables less than 50mm etc. is for dwellings only?! I didn't question this too much as I managed to save ÂŁ125 each on square D RCBOs I'd been quoted from wholesaler to fit the obsolete board)!
Cheers
