Among many mistakes he didn't properly protect it from the elements, a breaker has rusted and the tap-off is loose. Needless to say, the usual ancient stuff. Question: Can I replace EQ-P breakers from ITE with these from Siemens? http://www.homedepot.com/p/Siemens-25-Amp-Double-Pole-Type-QP-Circuit-Breaker-Q225/100183751 One of the customer questions asks that and a guy answered yes but I am skeptical because there are a lot of incompatibilities in American breaker systems. For example, while the Cruise Hinds breakers I have (I think that's now Murray) look identical they do not fit. Almost but not quite, going only 90% of the way in and they are 1/20" too fat. Roughing in a whole new panel would be MAJOR structural rework. -- Regards, Joerg http://www.analogconsultants.com/
