Breaker in Main Distribution Panel Overheats and Melts
October 27, 2022
Location: Salt Spring Island
Regulated industry sector: Electrical - Low voltage electrical system (30V to 750V)
A 60-Amp rated heat pump was connected to a 40-Amp two pole breaker. The heat pump and hot tub were on the same bus location. The breaker had been tripping continuously and the homeowner had tried resetting it several times. It is very likely that all the above factors contributed to the failure of the electrical equipment.
