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

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.

Wiring a 230v ao smith pump : L1 and L2 connection

Hi, assuming you have 4-conductor wire, use the black and red wires for L1 and L2. It doesn't matter which goes to which. If you do not have a red wire, use black and white. The green or bare wire in a 3-wire cable goes to the ground. If you have 4-conductor wire, the ground wire is the one you used for the GFCI on the breaker--usually the white wire. Please let me know if you have more questions, and thanks for using FixYa.

I have a 2.5h 2 speed motor with 3 wires Black, Red, Blue & Green (Ground) My question is how do know what ones are L1 & L2 and N?

That model number is listed as a 230v motor (no neutral) The wires should be attached to terminals marked L1, L2 and A . L1 is high speed, L2 is common and A is low speed. Check the name plate for wiring information.

Have 2 black wires n 1 green is this 115 0r 220 volts n where do wires go l1 or l2

The TWO Black Wires are Phase and neutral and it's irrelevant which way they go on the motor, the Other is the earth and that MUST connect to the case.
Black, L1 & L2 the other green EARTH.
115 or 120 doesn't matter

How do i wire pressure switch 034-0195

Just put in series after the switch before the wirings
go to the electric motor. Put the two electrical wires
to L1 and L2 (Line In). L1 must be with normally closed ontact L3 while L2 must be with L4. (L3 and L4 - is Line out) for the motor terminal wires. Before connecting wires at L3 and L4, Check for continuity at L3 and L4. Set the muti tester at 1 x 10 Ohms..Then put the multi tester probe on it. The reading must be infinity or no reading at all. Then
connect the motor wires at L3 and L4.
