I have a wiring problem with my old Federal Pacific baseboard heater thermostat. I disconnected this thermostat two weeks ago thinking we were going to remove the heater. Now we decided to have a heater, but I don’t remember how the thermostat was wired. The incubator has two lines: one in and one out. Each line has 1 black, 1 white and 1 bare ground. I have attached a picture of the back of the thermostat. It has only 3 places to connect. Bars 2, 3 and 4. Can someone help me out and tell me what the hooks are for each stick?

This is a 240V distribution phase, so both hots are equal. The white wire should be marked as one of the 8 legal hot colors because it is not a neutral wire. If I were wiring in conduit, I could choose one of 8 colors, I’d use black and black because the hotspots are interchangeable; No need to distinguish between hotspots.

This thermostat is unipolar. They made a bipolar version with terminal 1, one connecting 1-3 and 2-4. It is left only as a convenient isolation block in terminal 3, it is never connected to other terminals.
Pick a wire from each cable; Join them (I don’t care as long as the code is legal; feel free to use terminal 3 as a splice block).
I have run the wires from the electrical box (not connected) to the thermostat and heater (not connected), now I have to figure out which wire to connect in order. This 12/2 gauge is red and black. Thanks.
A How To Guide On Electric Heater Installation
In the first junction box next to the first thermostat, attach the black wire from the panel to the wire nut, the black wire goes to the next junction box, and the short pigtail goes to the thermostat. Connect the red wire from the panel to the second wire nut, the red wire goes to the next junction box, and the red wire goes to the first heater. Connect the black wire from the heater to the other connection on the thermostat. Connect the ground wire from the panel to the junction box, then to the wire nut, then the ground wire to the second junction box and the heater.
In the second junction box with the second thermostat, run the black wire from the first junction box to the thermostat. Connect the red wire from the first junction box to the red wire from the second heater. Connect the black wire from the heater to the other connection on the thermostat. Connect the ground wire from the first junction box to the second junction box, then connect the wire with the ground wire to the second heater.
I have a 20 amp bipolar circuit and plan to run 3 baseboard heaters with 2 line voltage thermostats. I have made sure that the wattage draw for 3 heaters does not exceed 3,840 watts. I ran 12/2 wiring from the breaker to the first thermostat location that would control 2 baseboard heaters, and from there to the second thermostat that would control the 3rd heater. I’ve uploaded a quick sketch for visual reference. I’m sure I know how to install it properly, but just want to check the sanity before committing. I believe I can wire the tail of thermostat 1 to the other thermostat location (bedroom), and for the thermostats controlling the two baseboard heaters, the wiring seems straightforward. Any help is appreciated!
How Do I Install Mysa When I Have Multiple Heaters In My Room?
Connecting the wire from the line side of thermostat 1 to room 2 will give you what you want here. However, with a thermostat and 3 12/2s, that’s a lot for many single headers (20.25 cubic inches of box-full, while the largest standard equipment box in the Code is 18 cubic inches), so you should use would like Large box, say a 4″ square where only the gang core/mid ring is. You may also want to wrap each of the white wires in black tape to make it clear they are hot, not neutral.
Important Note: The number of heaters you can connect to one thermostat depends on the size and wiring of your circuit.
The number of heaters you can safely wire to one thermostat depends on the size of the circuit breakers in the distribution box, the type of wiring you use, and the wattage of the individual heaters. It is generally recommended to use a 240V circuit for multiple heaters and thermostats because 240V runs at a lower amperage. A 240-volt circuit operated on a 20-amp double-pole breaker can have any combination of heaters up to 3,840 watts. For example, with only one thermostat, you can install:

Important Note: When using with a thermostat, you must connect the heater in parallel, not in series. If you’re not comfortable working with electricity, hire an electrician.
All heaters must be connected in parallel. You can do this by connecting each heater directly to the thermostat, or by connecting each heater to the next—just make sure each heater is connected to a power cord. Please refer to the wiring diagram above.
