How to connect a motor

SOURCE: Replacing new AOSSQ1152

What's the source of the info that the two orange wires are Low & High?

Orange is an unusual color, but I'd say, with 99.999% certainty, that if you put a voltmeter across the two orange wires, it'll read 220 volts (nominal).

The two orange and one white lead give you the ability to run @ 110 volts -- there will be 110 volts between one orange and white and also the other orange and white.

For this motor you only need the two orange wires which will give you 220 volts between the two. Cap off the neutral/white wire (not needed) & connect the two orange wires, one to L1 and one to L2 on the motor (L = Line). And don't forget to connect the ground...

P.S. You should also have a GFCI on this circuit.

SOURCE: I have an AO SMITH

Hi and welcome to FixYa, I am Kelly

Black is High/ 2, Red is Low /4 and white is L2 / COM (115 VAC connection) Also shown in Diagrm 69 below link as common

Usually on the side of an AO Smith motor there is a nameplate with a diagram of the connections.
