Can you replace the MH main breaker on a 800A or 600A Speed d board with the MJ Frame breaker?

Issue:
Can you replace the MH frame main breaker on a Speed d board with the Powerpact MJ Frame breaker?

Product Line:
Merchandise Switchboard

Environment:
Speed D

Cause:
maintenance

Resolution:
Unfortunately, the MJ breaker is not a direct replacement for the MH breaker. The current Speed-D switchboard construction uses an MJ breaker, but if they are trying to replace the MH breaker a new Speed-D switchboard must be ordered.
