Oh we also had them install basic electrical before drywalling. The idea was that we would need to be able to run a 15A power tool simultaneously with a 12A shopvac, plus other smaller stuff. So we had the electricians install twelve split-duplex 20A+20A 120VAC receptacles around the perimeter for us, all on a single pair of circuit breakers. That kept the cost down and made the shop usable from the get go.

After The Move, I added a 240V/30A circuit for the dust collector (5HP blower), a 240V/15A circuit for the tablesaw, and another 240V/15A circuit that is shared between the bandsaw and jointer. Used 12g wiring (rather than std 14g) for those tools to help with motor start-up currents.

A further two circuits power the arrays of LED pot lights and bulbs in the ceiling now -- could have put them all on a single breaker, but a fear of being left in the dark with spinning blades overpowered the $15 cost-savings that might have provided.
