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...

Charlie

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

SOURCE: Wiring new motor

I am assuming you are running 110 vac. Usually there is a diagram on the plate with the motor specification. You want the low voltage for110 and high for 220 motor wiring diagram you connect the motor as shown. If it is not on that motor it maybe on the old one they are usually the same.


You will need wire nuts to tie together the wires.

Note if this is a capacitive start or switch start. Allot of pool pumps are Switch start.

The L1 and L2 are the load terminals. Connect the black wires to the L1 and L2 and the green one to the green colored screw.

Thank you for posting your question here on Fixya.com.


Part of your problem will be the snake has a reversing switch so it is not as simple as just wiring two line leads. I assume you have a DPDT switch for reversing it? If so line goes to the center posts/terminals, motor L1 and L2 go to one end, motor red and black to the other end, and a jumper crisscrosses from end to end allowing the reversing.

In essence, what has to happen is in one direction motor L1 and red get power from one line and motor L2 and black from the other; to reverse motor L1 and BLACK get power from one line and motor L2 and RED the other. All of this assumes you are connecting to 115VAC since that is the portion of the diagram you reference. If not, add a comment with what you are connecting to.

The higher the voltage the lower the amperage, so advantage is its more cost effective to run it at highe voltages since power consumption is I squared x Resistance. The resistance will be the same but the lower the current the less it cost to run it.

Someone cut the plug from a 230V Craftsman Compressor and wired on a 120V plug and plugged it in. What type of damage could have occured?


You should be okay. It just ran at half speed while it was on. If had been the other way around (hooking up 120v motor to 240v socket) that would have killed the motor.

Looking for a wiring diagram for an A.O. Smith Motor. Label partially tore off. Can read 56C fram, 16.2/8.1 Amps (assume 120V/240V, 1 ph) 3450 RPM, 1.4 SF, Type UC, partial part # ...D609FM


Thank you for posting your question here on Fixya.com.

That actually appears to be part of the serial number, not the part number at the end of your post. What are you trying to accomplish? With a description of your terminal board and the current wire arrangement I should be able to tell you what you need to know. Another option would be to contact us through our site at www.arrowmotor.net and send a picture of the board.
