Issue:
Replacement of I-Line main circuit breaker

Product line:
I-Line panelboards

Environment:
Maintenance

Resolution:
You may ONLY replace a vertically mounted main breaker in an I-line panelboard with the same model breaker. For example, the MAP36600 is obsolete and could NOT be replaced by a current series M-frame like the MGP36600. Consider replacing the panelboard.
