Installing a Dayton G73

I'm using 10/3 to wire a G73 unit. I assume the L1 and L2 are the "hot" wires (black and red). The ground (green) goes to the screw on the housing, what about the neutral (white)?

If that is a 240V unit then you are correct wiring L1 and L2 to black and red. Unless the unit uses 120V for something like a control panel, it doesn't need the neutral.

I am an electrician by trade, the neutral (left over white) is not necessary.

Not sure what wires you are talking about. Normally on a 115volt motor you will have L1 and L2 and a green ground screw. Black or red goes to L1 and L2 (either one). White goes to either L1 or L2 (either one) and the green ground to the green ground screw. These would be the incoming voltage wires.

I disconnected the pump and need to know where the red black aND WHITE wires go

Hi, this is John the Hayward tech. You say the wire colors are Red, Black and White. Does not seem that the wires colors were correct from the start. Not knowing your voltage let me clarify some things. Normally if you have 115volts coming into the pump you wire colors should be Red or Black to L1 White to L2 and a green ground to the green ground screw. If you have 230volts coming into the pump the two hot leads are normally red and black with a green ground. The red and black wires go to L1 and L2 does not matter red or black. The green goes to the green ground screw.

The power cord has a green ground wire; two hot wires, which are black and red; and a white neutral wire. Attach the neutral to the middle connector and the two hot wires to either end of the terminal.
In order to safely ground the machine the green ground wire must be securely connected to the dryer frame. There may be a screw on the frame where you can attach the ground

I take it the wiring harness in front of me is 3 Phase. I have a Green wire, Red, Black and White. The wiring diagram on the back is marked L1, L2, N, E. Just need to know which wire goes where thanks.

It is not 3 phase...just single phase 240V....L1 goes to the one hot side of the 240 v, l2 goes to the other hot side of the 240V, N goes to neutral, and green goes to earth ground (metal box)
so....L1=Black L2=Red N=White E=Green

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.

Installing a Dayton G73

How many amps is your service? And what gauge wire did you use for the heater?
If your service is only 40amps that is your problem. You don't have enough amps for the heater and the rest of your house, you will have to upgrade your service.

Dayton G73 wire hook up with 10/3 NM-B wire

Red wire is not needed. Be certain 208 volts is read across black and white. Cap off the red.
