I completed (passed final inspection) last October (2019), and I'm getting ready to start electrifying my shop. I had decided early on pulling a building permit that included electric, was too much for me to do in one pass - I'm very glad I made that decision. I've done some research here and on a different website forum, and wanted to get some additional opinions.
Here's what I have decided so far:
100A breaker + feed to barn
200A panel - 42 slots
All EMT, use compression fittings and conduit as ground
All LED lighting
Here's where I'm struggling:
1) I located the service entrance in the rear side wall. To run power to the second floor, plus to the other side, will require a lot of conduit if I break out each circuit. Is it common to put a sub panel in upstairs, and one on the other side to minimize wiring?
2) The more I think about it, the more 42 slots in a panel seems... excessive. I don't know how to go about laying out my electrical on the interior either - I was hoping I could just run power along both sides with sockets, lighting, and the one required GFCI, and add as I need them. But... if I go with a 30 slot breaker, I might regret that decision.
Ground floor is 20x35, second is 20x30.
Thanks!
