What phase connections are used in a single phase I-Line interior?
Issue:
Does a 1 phase I-Line interior have 2 or 3 bus bars?

Product Line:
Panelboards

Environment:
I-Line Panelboards

Resolution:
I-line panelboards all have 3 bus bars. However,  typically in a single phase application, the A and C phases are used for that application when it is factory assembled from the plant. It is always a good idea to verify the phase connections before purchasing a new or replacement branch breaker.
