Wondering if anyone knows anything wrong with this installation according to code? I'm about to do a job on a storage building that is approximately 225 ft. It is divided up into individual units. There is a 200 amp. service on one end of it. I am planning on running a sub panel approx. 200ft. away on the same side as the "main panel". I will be running 3/4" conduit with 3 #6THHN and 1 # 10 for ground. I will put a 50 or 60 amp. breaker ahead of it. Out of the subpanel, I will go into one of the storage units to supply lights and a couple recpt.. I will put the recpt. on GFI . All will be run in conduit. I guess my main question is, at that distance, is there anything that says I can't put the panel on the inside instead of the outside? The neutral and grounds will be separated in the subpanel. Just trying to check all the angles before I start the job. Thanks for the input... [Linked Image]
