Is there anyone on line who can advise me with answers to any or all of these questions
1) When we converted and renovated the surgery house in 1996, the then electrician had me earth bond all of the radiators as we were using plastic pipe. Is this still necessary and / or best practice and if so what size conductor is suggested?
2) Similarly he had me bond the metal sinks and tap tails. Is this still necessary and / or best practice and if so what size conductor is suggested?
3) He has a maxim of not having a switch or socket within a metre of the edge of any sink bowl. Is this in the regs, good practice or simply an opinion?
4) I put all of the fans into the rings as a switched fused spur but am wondering whether the new ones could go into the lighting circuits (all fans domestic kitchen or bathroom type) Is there a benefit in terms of spikes and interference with things like laser printers / fax machines plugged into the mains with or without spike arresters? All the circuits will be RCD protected.
All helpful advice gratefully received, thank you.
