Question out of theorotical interest, can you connect the earthing systems of two PME supplies to achieve equipotential bonding between the two electrical supoplies or devices they power?
What are the pro's and con's of this? I understand the implications of PEN faults which might make the earth have touch voltage but if there is equipotential bonding between two earth systems would the earth fault current (earth which now carries live voltage from neutral) not flow through to the earth of the other PME supply?
Appreciate your thoughts.
