Proper wire hook up

I have only 115 going to pump measuring the Black wire. White wire is common Hooked up both black and white to L1 and L2......motor started and blew 15 amp fuse and motor got hot. turn all off and disconnected. I thought I had two 110 going to L1 and L2. White wire shows continuity and also about 10 volts. Should white wire be connected to Terminal A.???

SOURCE: What wire do I hook up I have a green to go to

Thank you for posting your question here on

It doesn't matter which line connects to which line terminal. Put white and black on L1 and L2, It won't matter which one is on either terminal. Green of course goes to the ground screw.

SOURCE: I have old spa motor

The motor should work if you connect the black wire to L1, white wire to L2 and green wire to ground. The red wire should be cut so the conductor does not extend past the insulation and the end wrapped with electrical tape.This should be correct if the motor is a 120 VAC motor. If the motor is a 240 VAC motor then the white wire is not really neutral. It should be wrapped in both the motor wiring area with black electrical tape and the other end in the timer should also be wrapped with black tape.

If this causes a problem because you now have no low speed for the spa then the only way to get the low speed is to squire a 2 speed motor.

I hope this helps.

Can't hook up power cord to main motor on Hoover model F5915100

You have a black and white and green wire. Green is ground white is neutral, black is hot . Should say on the motor either L1 = black wire. L2 = white wire , G = Green wire or it say H = black wire, N = white wire , G or the symbol for ground = green wire

My pump is wired for 120 and the diagram shows that a black trace wire to terminal B and a black wire to terminal A.Know my problem is the way its hooked up is a black wire on A and a black and white on...

The black and white wire is the trace wire. Using the A and B posts will be the 230 VAC connection. There should be another diagram for 115VAC telling you to move one wire to L2 and the other wire to I believe B. If the 115V diagram is not there is the motor rated for both 115 and 230VAC? If you need more help reconnecting the motor for 115 please provide the motor model number. It is likely an AOSmith motor with about a 10 character number for the model.

Does it matter if use 220 or 115... looks like i have 25 amp in the box with gfi.. need connect the wire to back of the motor.. outside i have the big circular 3 pronged connection to the outlet... do i...

220 VAC is more efficient ... so there is some cost savings in the money department. Volts X amp = watts generally ... there is still a savings because you will actually consume fewer watts at 220 (watts is what you are purchasing form the power company)

Wiring depends going to use 110 or 220? if 110 ... black is hot and goes to L1 ... white is nutral and goes to L1.

If 220 ... black is hot and goes to L1 - white is hot and goes to L2.

Your owner manual has a good picture and description of this.

In the plug ... 110 - neutral should go to the left slot.

Is your breaker 110 or 220 (single pole or double pole - one slot or two slots)

These voltages are not compatable!

I suggest you use this pump at 220.

T101 R Clock will not turn

The "Line" is the power source. The "load" is the device that is being powered.

typically the green wire is the ground wire. I strongly urge you to verify your assumption that is is the common wire. If the green is indeed the ground, and it gets hooked up to common, you will be energizing the cabinet of the unit and posing a serious shock hazzard.

Your curcuit will be as follows.

The power source "Line" will have wires going to the timer. (hooked to the "line" terminals on the timer.)the timer then is supplying the power to the pool pump, and we will reffer to it as the "line".

The two black wires from the pump would be hooked up to the "load" side of the timer.

Typically they would be labled line 1 and line 2 or "L1" and "L2"

If yours are not labled so, describe exactly what terminals you have in detail in both the pump and the timer.

Wire wayne 1.5 hp irrigation motor.

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.

Pool pump wiring

I DON'T REALLY LIKE TO GIVE 220 VOLT WIRING OVER THE INTERNET,LET ALONE THE PHONE,but I have a good feeling that if you all replaced the seal, you have an understanding of what you are dealing with: 1st make sure all power is disconnected,Breakers too(hey I have to say this so don't take it to heart), now the two black wires are 115 volts each, and the white one is ground, now enough said, the wires going from the source, (pool house,pump room), should be one white,one red, and one green, if this is the case the black and white wires, are the ones to hook up your black wires to, it does not matter (which of your black wires) go to either the red one or black coming from the source, and if your white on the motor is your ground it should goe to the green one coming from your source, if you don't already have them,I SUGGEST, you go to home depot,or lowe's and purchase the BLUE "water tight" wire caps, they can and are a "life saver anytime electrical is used around water, they cost some, but isn't a life worth a buck or two more? remember 115 volts can kill you if your around water 220-248volts will really kill you, so please check and double check all that I have told you. make sure everyone is clear,(pet's too), and flip the breaker, and you should be in business, god bless, happy 4th, and please let me know if I can help more

Hooking up my heater

The white is the common neutral, it is probably a 3 wire unit, and you are missing the ground wire. Check inside the control panel and see if someone wired it using the white wire for the ground, it will be screwed into a terminal lug. Check the schematics to see if the unit requires a common neutral to run the controls.
