When transferring back to utility power, transfer switch Generac 4945-1 200 amp main breaker trips (when several central AC units are operating from generator power). In trying to replace main utility breaker with identical Siemens unit, cannot get old breaker off of blades to remove.
Have removed single screw in center top of breaker that holds top of breaker onto ATS back panel. Pulling on top of breaker allows the breaker to pull out about 0.5” but then stops and further pressure tends to pull blade mounting from back panel of enclosure.
Any ideas on why breaker is stuck and how to extract will be appreciated.
