We are not given any facts, statistics, evidence by the IET and expected to comment.
I'm no scientist but can apply some common sense.
Specifically AFDD, Foundation Earthing, Surge Protection.
I noticed that Kirsty from Surge Protective Devices Ltd is on the JPEL panel as an advisor. (No vested interest there!)
How many manufacturers are there in JPEL?
Can we have the facts please.
