To Surge protect or not Surge protect that is the Question!

Hi,

A wholesaler tried to tell me that Surge protection is now a requirement in DBs under 18th Regs today. Im pretty sure thats rubbish but just wanted to put it out there. I know alots been added on SP in the new Regs but Im pretty sure its still only risk assessment driven and not a requirement in a single dwelling where cost out ways potential loss. They also tried telling me that surge protection from lightning is required, but I'm fairly sure that theres a probability calc for lightning (if anyone can remind me of it that would be great!) that I did on a design course a few years ago that proved that lightning in this country wasn't frequent enough to warrant a 'SP protection needed' outcome of the calc.

Cheers chaps

I'm happy that SPD have a place. But at home I've never had an incident that caused damage, nor do I know anyone that has had an incident. So I rank them right up there with the 6mm 32A cooker bonfires on Christmas Day, just saying. .

Am I correct in thinking surge devices are single use only and once used should be replaced?
