pool pump wiring

I replaced the AO Smith electric motor for my pool pump.I did not check to see if the old one was set to 110 or 220 volts.I have a 20 amp single breaker at the pump and a 20amp breaker on the main panel.Can you tell which voltage? From the panel by the pump there are 2 green wires and 1 black to connect to the pump.I have set it both ways and it immediately trips the breaker.
Thanks.

A single-pole C-B indicates a 120 volt motor-circuit,and one of the two conductors in a 120 volt circuit is required to be "Identified" by the color "White" ONLY, and no other color.The Identifed Conductor is AKA as the "Neutral" , and more technically, the Grounded Circuit Conductor.

I suggest you invest in a lo-cost needle-type voltmeter that can accurately measure both 120 and 240 volts so you can make positive tests-for-voltage across the 2 wires that connect to the motor prior to completing the connections.

Also, the motor may be a "dual-voltage" design that can be connected to either a 120 or 240 volt circuit. Obviously, the type of motor-voltage connection selected must conform to the voltage across the two Branch-Circuit conductors that connect to the motor.

Good Luck, & Learn & Ejoy from the Experience!!!!

You seriously need to call a qualified electrician. Quit trying to kill yourself and make the call!

I tend to agree. If you do not even know the difference between 120 and 240 you really have no place working on this stuff. ESPECIALLY where a pool is concerned.
PLEASE bring the motor to a motor shop or have an electrician come and check it out.
"Two greens and a black" sound an alarm as well. You'd be WELL served having someone come out and check everything regarding this pool installation.

Sorry buddy. Truth hurts doesn't it.

If you do attempt this task you are obviously NOT qulaified to do please remember water and electric don't mix.
Your family's safety is at risk. Or maybe you don't care and are only interested in saving a buck.

Thanks.
If i read this part correctly the wires comming from the electrical panel to the motor are these colors. So the origninal installer had no idea what he/she was doing either.

On top of this, you decided to just try it a bunch of different ways without regard for your safety or the safety of your family.

It is time to call a pro. Your grounding may not be correct or any number of other issues could also exist. Just because you made it work for today, does not mean that you have no problems. You may not find out about the problems till somone is hurt or killed.

cobrarea,

Your responses were inappropriate, so I removed them. Please do not post further childish responses. I agree with those who have told you to find an electrician.

There is a reason that pools and hot tubs have very specific code requirements. As others have stated, electricity and water do not mix. Only very skilled and qualified do-it-your-selfers and electricians should tackle pools and hot tubs.

Please stay safe.
