so I just replaced my 2 HP motor with a new 1 HP motor (an a. o. smith centurion 56Y 1081 1HP if I recall correctly).
It can be wired at 230v or 115v. I left it at 230v (default) because that's what the 2HP was set to and I didn't want to mess with it.
My question is stupid - what's the difference? If it's at 115v does it really use 1/2 the electricity? If so, does it produce half the flow?
So how do you decide what's best for your application?????
I haven't seen anything on the power curves that makes this apparent... thanks for any advice.
