Should I be worried or not? I've got quite a lot of metal faced
plugs / switches, and this weekend whilst generally pottering around I
happened to touch my voltage testing screwdriver to one of these
plates and discovered that it was showing something around 12v. This
was consistent then across all of the other faceplates that I touched
with it. I took the switch off and found that I got the same result
on the earth cable.
The device I used was the little red screwdriver in this item (http://
tinyurl.com/32xxka (links to B&Q)) which displayed a flickering 12V
Is this normal?
