I am responding to a home inspectors report for a client of mine. There are many mistakes made in his interpretations of our code. There was one line item of which i had never heard before, and before I responded I wanted to make sure no such rule existed. It was written " the ampacities values of the branch circuit breakers should not exceed 3x the ampacity value of the main breaker and thus the service size should be increased." My question is; does any such rule exist?
