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.

Re: Installing a Dayton G73

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

How do i wire a pull switch, it has l1 and l2..

What are you trying to fix?
If you are working on a 120-volt heater, you must be very
careful to wire it properly.
Make sure any ground connection is made before you attempt
to use it. Otherwise L1 and L2 are the hot (black) and
neutral (white).
Have someone help you who has experience with electrical
wiring connections.

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.
