Ground Fault Protection
Ground Fault Protection
(OP)
Is GFP (ground fault protection) a requirement for 480V distribution panel in NEC world?
We have a utility transformer (12.47kV – 480V), then a 480V distribution panel, then a dry type transformer (480V – 120/208V) and then a 120/208V distribution panel.
I understand that GFP is not required at 120/208V panel. So is the GFP required at the 480V panel?
