A client has an older square D switchboard, 120/208 1200 amps and during a shutdown for a generator test recently we discovered that the B phase was not opening. I tried several times and each time the A and C phase opened but not B. The breaker is a PAL361200 and is obsolete. I have a gear guy at the supply house looking into it. I just want to be sure I have investigated all options for the client since I know they will ask me about it so I was curious about getting a used/refurbished unit or having it repaired. Does anyone have any experience with any of these options? On the interwebs I see various sites selling used and "refurbished" circuit breakers but I am a little skeptical about getting a quality functioning unit. I dont know much about the repair option either. Obviously they would not have a main while it was being serviced so I would need to bypass it temporarily. If these have a history of being junk than maybe putting the same thing back in is not worth it. Thanks.
