Can an R Frame Main Breaker in an HCP/HCRU I-Line Panelboard be Top Mounted?
Issue:
Can an R or P Frame Powerpact main breaker in an HCP/HCRU I-Line panelboard be top mounted?

Product Line:
I-Line panelboards and accessories sold and supported in the USA.

Environment:
Installation

Cause:
Incoming conductor location

Resolution:
Top mounting is not an option for the R Frame.  Heat rise specifications limit where the R frames can be mounted in an enclosure.  The factory will always install them in the lowest location in the panelboard. However, the P frame can be top mounted with no issues
