How do they rate air compressors at 5HP when they have a 3/4 or 1 HP motor
driving it?

Thanks.

You should be able to use 14 gauge wire.

It'll drop about 4 volts at 12 amps over that length, but that
shouldn't
worry a fan much.

You could use #14, but there will be a lot of VD at startup, ...

How did you determine that, and how much, specifically, are you thinking
is "a lot" for a fractional hp fan motor???

Not to nitpick but wouldn't a motor drawing 12 running amps (if the OP is
correct) be in the realm of a couple hp? If I recall my 5 hp compressor
motor draws around 12.


#12 isn't all that much more expensive.

That's true, certainly, and I have pretty much quit using 14, but if
it's a dedicated circuit I don't think there's a chance in the world the
difference would make any practical difference at all.

If, otoh, there's a chance of wanting something else, that would
necessitate it in all likelihood.
