I recently had a 50 amp inlet and interlock kit installed at my home for storm season. Yesterday I tested the system without problems. Once I switched back to city power, the breaker for my hot water heater keeps tripping. When attempting to reset the breaker, there was a pop and sparks came out of the panel. Am I looking at a faulty breaker or something else?

TIA

Unplug your water heater and try again.

Why does a gas heater need power? Is this for tankless? Just curious.

if that breaker is just a plain breaker, a new one should be like $7-10. I'd just replace it. The sparking is not a good sign.

you shouldn't see an arc jump out of a breaker, im feeling that is a breaker issue

breakers are so cheap anyways might as well switch it out

Had same thing happen to me last week but w/o the 50amp plug issue. Replaced the breaker. Still did it. So shut off power to heater (electric) and checked continuity to element as a bad element will trip breaker. All good. So pulled another panel on heater and checked thermostat. It was fried. So bought a new one( $20 at plumbing warehouse) and replaced. Made sure any black wires were sanded and the thermostat was flush t I tank wall. Bingo. Saved $400-$500 +. Water is hotter now at lower setting. Easy to do. I am nooo electrcian but do have a multimeter.
