im wiring my shop and have 2 pieces of equipment i am not sure of. a
true 3 hp compressor and a 3 hp unisaw. is a 20 amp circuit enough for
each or these or do i need to go to 25 or 30 amp? the compressor says
it needs 15.4 amps and the tablesaw says 15.5 amps. thanks all ...

Whatever you decide on ampacity, run 10 ga wire, then use the c'brkr size of
your best informed choice.

The Unisaw will run fine on a 20 amp breaker (mine does), and if for some
reason you feel that you need 30 amps later on that circuit, the 10 ga wire
will allow the increase without further ado ... you'll be glad you did.
