I'm getting ready to run electricity to my outbuilding. It is already wired, I've just got to supply the juice. Here is my question. Would it be better to run a subpanel from the house panel or install a panel and drop power straight from the pole? I have a 200 amp panel with 3 empty slots for breakers, or could also use tandem breakers. The building is about 100' from the panel, so what gauge wire would I need for the subpanel? Thanks, Randy J. P.S. Thanks for the info on the roofing situation it was very useful. I read posts just about every night, but I'm just a DIY'er. I try to leave the advise to the pros.
