Can the secondary main breaker in an MPZ10S40F be a GFI breaker?
Issue:
Can the secondary main breaker be a GFI breaker in a sealed mini power zone unit substation?
Product Line:
Low Voltage Transformers
Environment:
Mini Power-Zone LV Substation
Resolution:
The standard secondary main breaker is a QO260. If a QO260GFI were used, the secondary would no longer have a neutral connection and would be limited to 240 volts only and no single-pole 120V branch breakers would be allowed.
