It says it's got a 2HP motor on a 115V circuit, which is impossible
according to a number of people on this newsgroup.

You might want to call IR and tell them they have a misprint. *VBG

Won't work on a 15A, 115V circuit. Should work OK on a 20A, 115V
circuit however if there are no other loads connected. Note that
current draw is listed @ 15A. You should not connect a motor that
draws 15A, running, at full load to a 15A branch circuit.

Theoretically speaking, 2HP is 2*746W = 1492W or about 13A @ 115V, so
even if the motor were 100% efficient it would still not be acceptable
on a 15A circuit. (shouldn't load a circuit to more than 80% of its
OCPD rating as a general rule, not sure if rules are different for
motors or not. In the case of a 15A 115V ckt. that would be 1380W or
12A.) The compressor you describe draws 15A which is less than 20*0.8
or 16A so that is why I say that that should be OK, although it still
might blow a fast-blow fuse on startup.

So, no, in short you shouldn't connect a 2HP motor to a 115V, 15A
circuit (typical household circuit.)
