The customers Nema 14/50r located in the garage was being used for a car charger and burnt up. When the wiring and device failed it caused significant ground fault conditions that tripped the main breaker outside, left disconnect along with damaging the breaker where it would only have one leg working. We supplied and installed (2) new 150 amp main breakers in the disconnects and power was restored. We removed all the non listed breakers on both panels and supplied and installed new breakers. We supplied and installed (2) lifetime warranty surge protectors one for each panel. We wired in a new circuit for a new Tesla Wall charger for the garage and set it for 48 amps. We showed the homeowner how to use the charger.
