New to me acreage with 30'x40' shop (Lester building), no power currently...getting ready to run 100 amp service when ground thaws.
Shop will be used to for woodworking and automotive work. Biggest power draws currently will be Campbell Hausfeld Pro-180 mig welder, 240v 60 gallon air compressor, old-school table saw. May add plasma cutter and heater down road.
At previous house I had electrician run 240v line to garage. I pulled that breaker box from old house and plan to use in the shop.
Air Compressor: Box already set up with 20A/240v circuit breaker. Compressor will be ~30 feet from the box, by my calculations I should be able to use copper 12AWG, correct?
