Hi I have brought ( Varilight Mirror Chrome, LED Dimmer Switch - V-Pro Series, 1 Gang (Single), 1 or 2 Way, 400 Watt )
when I tested the dimmer face plate after screwing it in the wall my digital tester showed a reading of
I then tested it with a screwdriver tester but got no current.
I tested another room on a different dimmer on the face plate and the results were the same.
all dimmers are earthed yellow and green wire and the C and L1.
my question? is this 12v current reading normal with metal plates or do i need to see an election.
