I've got a job at a mobile home where I think the main breaker is going bad. I can't see the brand on it, and it is an odd one. The contacts where it attaches to the buss bar come straight out of the end of the breaker and pushes into the buss bar like a knife blade disconnect does. Any idea of the brand and where I might find a 100 amp? Thanks... Steve

Zinsco? Best bet is if you can submit a picture,otherwise a WAG.

maybe a wadsworth? Is there any red popout by the switch handle?

yep, I think that's the breaker. Unfortunately, the mobile home park owners told me to go ahead and change out the panel, which I did today. Now I have a supply of 20 amps my own, and 1 possibly bad 100 amp. Thanks for the replies. It is an odd breaker around here. Don't think I've seen them before, maybe one other time, but not sure. Thanks again. Steve
