Those are nothing more than a GE label on a Siemens/Murray DF breaker. :blink: So Siemens DF breakers aren't problematic? I'm asking since I don't use them much, or GE for that matter.
It's a GE as far as i can tell, all i'll say is less problems w/them Pete
Seems to me the manufacturers are driving both UL and NEC more than anybody else is.
Dig, and you'll find the same UL and CSPC members as either cmp-2 seats or alternates over the last 2 decades
