I've used Bates twice. They came out and trenched to my garage, upgrading a 30 amp circuit to a 50 amp and installing an 220V 50 amp Tesla charger for me.
Recently, they came out and upgraded a stove outlet from 3 wire to 4 wire. The outlet, the way they first installed it, wouldn't allow the new stove to be pushed back to the wall, they came back and reoriented it. Amazing customer service and speed.
Reasonably priced, but, more importantly, they could get here faster than anyone else I called.
Would call on them again. Also, the tech and his helper were super friendly.
