I have come in possession of a Craftsman model 919.165200, 5 hp, 20

repair? Anyone come across this problem before?

A single phase 5 HP motor at 115VAC draws 56 Amps. A single phase 5
HP motor at 230VAC draws 28 Amps. A five horsepower compressor is
huge. Most garage 110VAC circuits are 20 amps at best. 230VAC
circuits are usually 30.



You're all forgetting the funny way they rate horsepower on compressor
motors. A "5 HP" motor might really be 2 HP or less.

My current 6 HP compressor runs on a 20A 240V breaker, and it doesn't
put out as much air as the ancient 1.5 HP compressor that it replaced
when the old one finally bit the dust.
