A simple question, but no doubt a complex answer. How can you tell if you house has PME ???
Hi Pauls,
easy PME (TN-C-S) has main Earth cable connected to side of companies cut-out, along side the Neutral tail,
TN-S will connect to cable sheath with clamp below cut-out,
TT will have a rod outside, so only 3 choices!
