Issue:
Design for single phase main breaker
Product Line:
Panelboards
Environment:
I-Line Power Distribution Panelboards
Resolution:
Because there are 3 poles on the busbar, main breaker I-Line panels always use 3 pole breakers, whether single phase or three phase. For single phase panels, only A and C phases are connected to the utility power. The B or center phase is used only as a spacer.
