If you are using a 220V-240V appliance at 110V, you will need a transformer. If you are using a 110V appliance at 220V-240V, you can also use a transformer but may be able to get away with a (cheaper) converter though not with all appliances.
That's a 3 phase motor(ph3). And probably a 220v/460v? Or a 110v/220v, BIG difference! You'll need to figure out your supply voltage and wire it accordingly. Normally, if 220/460, all 3 black wires are hot legs, and this is probably what you have, because 110v will normally have higher amperage than what you posted. And if the motor runs backwards, switch any leg with 1 other. Hope this helps!
First, be absolutely sure that your motor is wired for 220v. If it is 110v and you apply 220v the motor will die instantly (after a loud bang). Also verify that your supply is in fact 220v.
Without exception 220v power should be supplied by two wires of the same color, as they are both "hot". Black and white wires are common in 110v wiring, the black being hot and the white neutral.
Every pool pump I have worked on has had two terminals where the wires attach to the motor, L1 and L2, wire orientation does not matter.
Evidently yours only has one. Apparently there is no wiring diagram on the side of the motor either, which is also atypical. Best bet is to call the factory for assistance with this.
Most pumps have the eiting diagam on the outer motor housing. What brand is the pump? Some motors have a jumper that is moved over to 220v or 110v post and the red/black(220) or white/black(110) stay on the regular screw terminals. Ground stays on the same terminal usually a green screw
Check to make sure that the pot lid o-ring is in place.
Verify that your plumbing is sound and has no suction leak.
Check water level in pool.
Make sure the voltage is correct. Many pumps come pre-wired for 220v. If you have 110v supplying the motor it will run at half speed. There is a diagram on the side of the motor showing how to convert to 110V. Make sure that your supply is 110v before converting the motor. If you switch the motor to run on 110v and hook it up to 220v it will ruin the motor instantly.
If you look at the wiring diagram on the motor plate it will show you where these wires go for 220v power, and where they go for 110v Power. If you know the supply voltage just place these wires as shown on the diagram and you should be fine.
Usually the wiring diagram for the motor is shown on the motor nameplate or inside the motor end cover. Unfortunately the diagram is not in the owners manual but this document should be read because it provides safety information. For this motor running at 110VAC, the manual recommends using 10 gauge wiring. Most pumps are wired using 12 gauge wires. Also, if a 20A breaker trips then a higher breaker may need to be used. If you are making wire or breaker changes then you need to have an electrician do the job. I hope this help.
Sounds like you may have a 220V pump. So you need to confirm that this is a 110V pump and not a 220V pump. There should be a label or more info on line with any other info on the label. If you can confirm that this is a 110V pump, then put a standard plug on the cord - the green is ground and the other two can be wired to either blade of the plug. If you do have a 220V pump and you connect it to 110V anyway, the pump will perform poorly and will probably overheat and fail.
