In todays episode we answer a question from Mike. He asks: "I had a commercial job where the plans state 200 amp 3 phase 120/208-4wire exterior surface mount panel with 200 amp main breaker. I was told by 2 electrical companies that i needed a panel board (which was $750) and by 1 electrical comapny i can use a basic loadcenter ($280) which is correct?"
