Isolation Transformer as a Separately Derived System
This would be in reference to say a 3 to 10kVA isolation transformer for an audio system in a residence or studio.
So the primary EGC makes it's way back to the main panel board, that's easy.
But for the secondary it's really a GEC (not a EGC) so how is it connected?
