let me state that i am a novice and have dabled somewhat in electrical work but am always seeking guidance and tutelage. so here is the skinny...there was previously 60 amps of service running to my shed( to a subpanel) from my main panel( which is a 200 amp service) by a 60 amp breaker. i will spare the detalis why i am reduing this. i would like to go back just the way it was but have some questions. one was the above done correctly? two: what is the largest main i can put in the subpanel? this may be a dump question. and do i need a main shutoff at that subpanel. three: how much/many circuits can i run off of the 60 amps of service in my shed. i will be installing a small shop and a bar. will go into greater detail as questons arise.
