I need to replace the main circuit breaker on my Crouse Hinds JA220CS service panel. I have attached photos of the original Crouse Hinds in my panel and a Siemans replacement that I think will work. Can any help me confirm if it will? This is the link to the replacement.
Siemens has acquired Murray, who made the JA220CS (verify on back side of breaker cover plate). They have issued a UL testing certification saying that the equivalent Siemens breakers have been tested and found to be interchangeable with the Murray parts and thus fulfil NEC requirements of being certified for use. You may request the sheet from Siemens compliance manager if it is not already on their website. I provided this sheet to Los Angeles County a few years ago - they had not seen it at that time (Surprised the inspector) - before purchasing the Siemens breaker. They accepted the Siemens breakers in Murray box. (need GFI/ Arc Fault for all new circuits in Los Angeles - probably California.)
