I have 200 Amp service in main house. Outbuilding is 150 feet away and will have small workshop loads (table saw, band saw, belt sander), maybe 6-8 more outlets and some average lighting needs. Will only be using one tool at a time. Was planning on a 100 amp 12 space (24 circuit) sub panel with 60 amp circuit breaker at main panel in house. I know I need to ground the sub-panel and disconnect grounding and neutral bar. What I need is some opinion on wire or cable sizes. I know this is asked a lot, and I apologize in advance. Do I need to pull 4 wires? Sizes? The wiring will be within 2" dia PVC pipe buried 42" below grade with large curves at each end. Unfortunately, the end of the conduit (installed by previous owner) is outside the house perimeter (but inside the outbuilding) so I assume I need to use outdoor rated wire? Can anybody help with wire sizing for "typical residential workshop" needs? Any other comments/tips? Thanks in advance!
