Review on UBIZ3030 R3830 Replacement from Connecticut Electric by Rusty Smith

This 30A double pole circuit breaker fits my son-in-law's old Zinsco panel as intended. The switch he replaced was for the water heater. The arcing contacted one of the tires and the heat generated by the arcing affected the spring tension of one of the clamps. Tire damage was minimal, but I installed this new switch on an undamaged section of the tires and it works fine. Love the fact that this switch has screws for the load wires instead of spring terminals like the old switch. My mothers-in-law are happy to take hot showers again.
