Your wires- Black=hot, White=common, bare copper wire=ground.
Motor wires- Black=hot, White=common.

Connections: Black to black, white to white, bare copper from line in to motor frame.

The wires from the motor should have been designed to carry the power load. Heavier wiring is always an option, to a point.

H ms steve,trying to make sure my 1 hp magnetek 1725 rpm motor is set up for 230 v...magnetek century ac motor the only numbers I see is 164014 please help


There should be a diagram on the side of the motor for proper wiring. Some motors are dual voltage capable others are either 240 or 120 line supply only. They will not be convertible! So you have to bring in what they are labeled as.

Some times the diagram is inside the cover where you make the external connections for in/coming in supply wires.

I have a 12 inch chraftsman table saw with 2 wires coming from motor. The wiring diagram inside the cap shows it to be wired for 240 how do I wire that thru a switch and to a three wire recepticle


Not quite sure what your question is - Are you trying to plug a 240 into a 110/120 outlet? Or are you trying to plug this into a 240 3 prong outlet?

Traditionally, table saws don't come with a power cord - you must supply one. Usually on the motor there is a metal plate that describes volts/amps/phase/hp etc. Get the Volts/Amps from this plate, then measure the approximate distance between your table saw and the 240 outlet. The gauge of the power cord depends upon the Volt/Amps and the length of the cord. There are many volts/amps vs length for wire gauge conversions on the net. I always get a bigger wire (smaller gauge) than what is recommended. Expect to pay $100 or more for the cord (don't be cheap here). If you have an under rated cord, you can start a fire, burn up your motor, melt plugs into outlets and have to replace the outlet (don't ask how I know).

I'm a little suspicious of the "white and black" wire from 240 - it's usually "white and red" with a "black" ground. 240 is made from two 120's - opposite sine wave. So black is usually the common ground, while the white and red are the two 120's. Volts between white-red=240, white-black=120, red-black=120. If you're absolutely sure that white-black=240, then you can just connect a ground wire to the motor case. Many home table saws can be wired for 240 or 120 - you need to make sure that you're hooking 240v to the correct wires. If you're uncertain at all, then don't do it.

I have wired 120 to a 240 motor by accident and the motor ran - it had no power and didn't spin at full RPM. You can damage a motor this way, so I wouldn't recommend it. I have never put 240 to a 120 motor - so I don't know what happens (guessing you could burn up the motor coils).

With all that being said, if you have 240 outlet with 3 wire receptacle, then just use a multi-meter to determine the 2 "hot" and the 1 ground. Volts from hot1-hot2=240, hot1-ground=120, hot2-ground=120. If you don't have a multi-meter, buy one (approx $12). Once you have it wired up, then try the motor by flipping the switch on then off again. If the motor didn't spin, then you did something wrong. If it hummed but didn't spin, you have some connections wrong inside of the motor. If it spins the wrong way, then your wiring inside of the motor is wrong (doesn't help to flip the wires on the outlet). If you blew a circuit breaker, then the wiring to the motor is wrong.

How do I wire a Polaris PB4-60 in the USA (115V)?


I am not sure if this will help you out any, but here goes:
Line1 & Line 2 are your Hot Power Wires coming into the motor.
It does not really matter which wire goes to which post of the motor.
This will remain true if you are bringing in 110-115-120 (these are all the same, people just refer to them differently) which also is referred to at times as "Low" voltage, and the same goes for 220-230-240 (again, referred to differently) which is referred to at times as "High" voltage.
Whether bringing in Low voltage or High Voltage, the wires you bring in will number only three:
  • Ground
  • Hot
  • Hot (potentially Hot)
Low Voltage (115) will have:
  • 1 Absolute Hot Wire = Line 1. Normally Black
  • 1 Potentially Hot Wire = Common/Nuetral Line 2, normally White
  • Ground/Earth = Normally Green
High Voltage (220) will have:
  • 1 Absolute Hot Wire - Line 1, Normally will be same color as Line 2 or Black/Red
  • 1 Absolute Hot Wire - Line 2, Normally will be same color as Line 1 or Red/Black
  • Ground - Green
In either of the above voltages, it does not matter which wire goes where, as long as a Hot wire goes onto Line 1 and the other "Hot or Potentially Hot, if 110", goes onto Line 2. Do not put a Hot wire anywhere else and Do Not put a Ground wire on either Line 1 or 2!

Most Motors are coming out of the factory wired for High Voltage Set up (220), so you will have to move some wires or a terminal block, to set the motor to operate at "Low" voltage (115). These motors are "Dual" Voltage, they have the capability to run either 110 or 220. But they don't magically know which voltage is being supplied.

Good Luck

How do I find a wiring diagram for a utilitec pump?


If it's a 120 volt unit white is neutral and all other colors are hot- green (or bare) is always ground. The switch is always on the hot lead. Switch has two wire coming out of it (may have ground from the body of the switch) this brakes the connection from the supply line(hot) to the motor or device.
If this is 240v which I don't think it is because you have to have special receptical to plug it in

Which wire color do i hook up to line 1 & line 2?


Question posted under 240volt R8806P101C timer.

240Volt line, both hot wires, line1 and line2, are identical so wire color doesn't matter and either wire can connect to either terminal.

R8806P101C terminal block has 4 screws. 1 2 3 4 from left to right.
240volt wire from circuit breaker connects to terminals 1 and 3
Wire going to 240Volt Load connects to terminals 2 and 4

I see what you said ... still I want to say the following: It is to your benefit to keep the motor at 220 VAC ... Since you want to run it on 120 (I presume the motor is internally wired for 120 now - right?) did you change the white wire in your pannel to the neutral bus making the line 120? Also check the motor that it is wired for 120. It sounds to me like you did the line but not the load.

If the line and the load are both correct the next thing to check would be the start capacitor. It should be good since this is a new motor ... but it is not running. Have it checked.

Runs 1 minute, gets hot and shuts off help!!??


Need a bit more information.

Are you saying that you have set it up for 220V or that you are running it on 220V?

Many motors can run on either 120 or 220, but you must check the leads and make sure they are jumpered correctly.

Are you running on 220 or 120?
Are there leads with numbers in the connection box that have wire nut or jumpers on them?
