I'm in the process of installing solar and my plans derate the MSP main breaker from 200 to 175 because the backfed breaker is 60 amps.
Today I had a licensed electrician tell me I don't need to put in a 175 amp breaker and I'm fine leaving it. His argument was that no inspector ever looks at it and practically the bus bar would never be overloaded. He also said he'd need to pull a heavy up permit in order to replace the MSP main breaker.
I plan to call my POCO / AHJ / Inspector to get clarity on this but I'm curious to hear other people's experiences.
Is it common to skip derating breakers? Can the meter be pulled without the need for a heavy up permit? I though the electrical permit for the solar project covered the derating breaker (it's included in the electrical plans which were permitted for this project).
