Bit of an odd question here.
I was asked to install a shower, just the circuit at the moment for a friend whilst he is decorating his bathroom.
A provisional look at said job showed a CU upgrade (install) was requierd as he has a row of 4 switched fuses one for each circuit, lights, cooker, sockets and immersion Heater. Also no bonding to gas and inadequate bonding to water.
I quoted for board change which has been accepted on the result of a periodic which I'm doing prior to starting work, just in case of any hidden nasties.
So far so good but it turns out that during the war his terraced house cellar was converted to an air raid shelter. The front half of house has been re-inforced with upright steel rsj on brick plinths supporting more rsj joists under the living room floor. Then a very thick corrugated steel sheeting has been placed on top of the joists under the lathe and plaster ceiling of the cellar, between which cables have been run.
My question is what sort of bonding requirement would be needed to the steel? I'm assuming it would be the same as for a steel structure of a building. I'm doing the periodic tomorrow, just wondering if anyone else had ever come across this?
