Everyone,
I wanted to get some clarification on how to apply the following requirements from the NEC to the wiring of my shed. The shed is completely detached from my main home and has a burial cable running to it.
1: If a structure is completely detached from the main building and a panel is installed; it must be a main breaker panel (no sub panel) to shut off in the shed electricity if necessary.
2: At the point where power is supplied in the shed, a switch must be included to shut off power to the shed.
My question is simply this: It seems redundant to have both a switch and main breaker to shut off power to the shed. Can I just install - say a switch and use a sub panel and still meet code? Any ideas?
Extra Information: I am running a 100 amp service to my shed at 240V. The distance between my house and the shed is long; so, I used a 4/0 aluminum wire to supply the power. Originally, I was going to use a LB to feed a junction box inside the shed. This can reduce the wire size to something a 100 amp panel with a main breaker can accept. Will this still work even though the switch isn't right at where the power goes into the shed?
Finally - I would prefer the main breaker panel and/or switch to be inside the shed.
Thanks in advance for your help.
