Good used Zinsco circuit breakers that are in good condition without any corrosion on the contacts. The retail pric e is 50% higher than what i'm selling them for, price them in a store and see for yourself. These circuit breakers are hard to come by and are priced as follows:
Three single pole 15 amp $20 each.
Two double pole 30 amp $40 each.
Three single pole 50 amp $45 each.
