I have a 4 wire electrical source & a 3 wire 220v pool motor what should I do with the common?

SOURCE: Pool pump wiring

O.K. MONIKA READ VERY CAREFULLY!!!!
I DON'T REALLY LIKE TO GIVE 220 VOLT WIRING OVER THE INTERNET,LET ALONE THE PHONE,but I have a good feeling that if you all replaced the seal, you have an understanding of what you are dealing with: 1st make sure all power is disconnected,Breakers too(hey I have to say this so don't take it to heart), now the two black wires are 115 volts each, and the white one is ground, now enough said, the wires going from the source, (pool house,pump room), should be one white,one red, and one green, if this is the case the black and white wires, are the ones to hook up your black wires to, it does not matter (which of your black wires) go to either the red one or black coming from the source, and if your white on the motor is your ground it should goe to the green one coming from your source, if you don't already have them,I SUGGEST, you go to home depot,or lowe's and purchase the BLUE "water tight" wire caps, they can and are a "life saver anytime electrical is used around water, they cost some, but isn't a life worth a buck or two more? remember 115 volts can kill you if your around water 220-248volts will really kill you, so please check and double check all that I have told you. make sure everyone is clear,(pet's too), and flip the breaker, and you should be in business, god bless, happy 4th, and please let me know if I can help more

I'm guessing that you replaced the motor that goes to the pump, not the pump itself. You know the motor works just fine. Is the motor rotating in the correct manner(clockwise or counterclockwise) in relation to the rotation of the pump? Have you checked the pump to see if the impeller is working/rotating? Is the motor hooked up to the pump correctly, so that the motor is turning the impeller? Are all connections to the pump tight, so there are no suction leaks? Have you primed the pump and purged it of any air locks?

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.

Try this link: http://drawings.aosmithmotors.com/sendfile.aspx?ItemNumber=SQ1202&DrawingType=OUTLINE

There is a small portion that describes the line connections. If you need the internal wiring diagram you will need to contact me thru www.arrowmotor.net and well get it from AOSmith for you.

Your electric motor needs new bearings in it.. The capacitor gives the pump a kick to get
it going.

Hope this helps.
