Please verify the name plate to be 115 230 volt motor.there will be a schematic that shows you exactly how to hook up this motor depending on the voltage being supplied to it. The main thing is switching between 115 and 230 volts this is a selector switch this very easily forgotten about. Please make sure to check that and double check that to make sure its on the proper selected switch. Good luck

SOURCE: c/l pump 1hp. hook up

A motor set up for 230VAC will run on 115VAC but will overheat and shut down over time. The motor nameplate should tell you what wires need to be reconnected and how in order to operate the motor on a 115VAC circuit. Once you change the wires your motor should go back to normal operation.

SOURCE: My pool originally had a

Is it going to run on 230V then? If so you would normally use red and black. The white wire should be a neutral and the ground wire is obviously ground.

Do you have a meter you can use to confirm the voltage between the wires? If you do you'll want to start with red and white since you seem to think black was not being used before. If the voltage reads 230 and the motor is set up for 230 then attach one wire to L1 and the other to L2...it will not matter which is connected where as long as one is on each terminal. Insulate the black and ground the ground lead to the motor ground screw.

If the voltage is not 230 between those two check between red and black. If that is the 230 then insulate white and put red and black to L1 and L2.

SOURCE: Im hooking my pool pump

There should be a diagram on the side of the motor showing you where to put the brown and white for 110/220 volt operation. Most new motors of this size are shipped strapped for 220v. The two hot wires will go to L1 and L2 and it doesn't matter which wire goes to which lug. For 220v you will usually have 2 black or 2 red wires and a green ground wire. If it is 110v supply, you will usually have a white and a black wire, and a green for ground. Hope this helps. Since you said you are hooking to 220v the brown and white should be on the correct lugs if this is a new motor.

I have a 220 volt gfi breaker tripping its new install how does the gfi wire up

The bi-metal motor overheat protection switch is internal and it is activating probably with or without the ground fault interrupt they prevent electrocution and other devastation, do not modify anything. Do not hesitate, seek a very experienced pool electrician, NOW.

Wiring line side of 230v two speed pool pump. It has line 1-4 which do I use

There should be a schematic on that motor describing how to connect the power. You would definitely want to use 230 volts as this allows the motor to run more efficiently.

My new AO Smith motor does not have an L1 IT has L2, L3, and L4 so how do I hook the wires?

There is a schematic on the motor itself to show you exactly how to hook it up. The main thing is knowing whether it's 115 volt or 230 volt connection. Good luck any questions hit me back up.

A thumbs up would be greatly appreciated if answer is helpful for your question. THANK you and GOD BLESS

A.O smith pool pump tripping breaker

It you either have an impeller problem or capacitor problem on the motor. I would take the capacitor off and take it to a electronic or lexical shop to have them check it. It's only about 15 to 20 dollar pics if it's just your capacitor.

A thumbs up would be greatly appreciated if answer is helpful for your question. THANK you and GOD BLESS YOU.

I have a Pentair 2 hp motor. I have 2 black wires and one white wire on the supply line. I can see where the white and one black wire go but where does the other black wire go? Other terminals on the...

I WOULD THINK THAT THE WHITE WIRE IS GROUND AND THE OTHER TWO ARE LINES (HOT) HOW TO CHECK THIS ? THERE IS A 99% CHANCE YOUR 2 HP MOTOR IS A 230 VOLT MOTOR.. SO TAKE A VOLT METER SET IT FOR SAY 50 VOLTS AC, AND ATTACH THE LEADS TO THE 2 BLACK WIRES, SHOULD SAY AROUND 220-240 VOLTS.. THESE GET HOOKED TO A-B.. WARNING IF THIS IS A TWO SPEED MOTOR, DO NOT ATTEMPT TO HOOK IT UP, IF YOU HOOK IT UP WRONG IT WILL SMOKE THE MOTOR ! OK YOU SAY HOW DO I TELL IF ITS A TWO SPEED ? LOOK AT THE LABEL IT WILL HAVE 2 RPM'S LISTED. IN THIS CASE CALL YOUR LOCAL POOL PUMP MOTOR REPAIR GUY.. HEY U , PRIME THAT PUMP AFTER ANY PUMP REPAIR !! NEVER EVER RUN A PUMP DRY... GOOD LUCK ,, NOW GO GET WET... Jay FLORIDA
