i did see alot of push-matic breaker in this area but only thing i hate the most is 100 amp breaker when they go out they are pretty hard to find a replacement breaker for it and useally cost more than new breaker box will run for it .
the other pushmatic breaker box i ran into but i did not get chance to get a photo is the 3 phase pushmatic load center !!! now that is a rare item btw it have 400 amp main breaker but the bus bar inside the pushmatic is very instering arrangement there it will drive some peoples nuts with this one..
merci, marc
