Thanks to everyone who posts, I've borrowed a ton of ideas from the forum,and this section.Built a 20x23 shop in the backyard in Sept. Finally powered up. No switches and plugs yet, but power! Now to insulate and board before I finish it off. 100amp panel, 2 240 outlets (welder,plasma cutter) 3 15 amp dedicated outlets(large power tools), 12 outlets at 4 ft high(basic power tools). 3 at 8ft high (radio,tv,etc) 2 240 4000 watt heaters. 8 2bulb florescent fixtures and led task lighting over each bench. All armored cable 12 14 and 10. Am I missing anything?? I put a conduit. In to the attic incase I forget anything.
