Buying a compressor... do NOT want to underbuy.

That's the ticket right there.

Is that similar to your portable? Or do you have another type?

Right now I have a 3 gallon pancake compressor with a short line to a 10 gallon overflow tank. Plenty of air but the CFM sucks.

A true 1.5 hp 110v motor would draw almost 20 amps, and I think that's about the upper limit for household 110v wiring, most breakers are 15amp.

In other words, when they advertise a 2hp 110v electric motor they're WAY overrating the hp, 2hp 110v would need close to 30 amps to run.

If there are any electricians, please correct me if I'm off

{edit} they're probably also overrating their pumps cfm and volume, be aware.

2 hp at 120Volts(110 really doesn't exist anymore, unless you have voltage drop) but off the top of my head?? 1 HP =746 watts @120 volts= 6.2 amps x2=12.4 amps@ 80% of 15 amps(12) your ok with a 15 amp breaker
