You may have noticed the
prominence given to surge protection in the latest version of the wiring regs.
This is alerting you to consider providing surge protection
on most of the new jobs that you do. The point being that without electricity, buildings are sent
straight back to the stone age. It only takes one big surge to permanently
damage fixed wiring insulation requiring it to be replaced – an expensive and
time consuming task.
It can only be a matter of time for the Insurance companies
to realise they can avoid paying out on voltage surge damage claims by
requiring SPDs to be fitted.
Loads of SPD info. in the regs.
