Wireing three units together

I would like to know if I wired my new heaters correctly went form power supply 20amp breaker 12/2 wire to thermostat from thermostat to first heater black and red wire pigtailed a second wire and ran it to the second heater pigtailed black and red with a second wire to the third heater. also hooked up ground wires in each of the units.

Yes, you did a good job. Sounds like you paralled them. Which is right buuuut what size are these heaters. Add the wattage of all of the heaters and divide by 120 and that is how much current you will be using. On a 20 amp breaker you can only pull 16 amps safely. I think you will be way over unless the heaters are 600 watts each. You are allowed 1800 watts on a 20 amp circuit.

    Doesnt matter if the voltage is 120 or 240 you are only allowed 16 amps on a 20 amp circuit. just let me know the wattage of the heaters. On a 240 volt circuit you are allowed 3800 watts.You might be in good shape.

I'm replacing a non-hydronic electric baseboard heating unit with a Fahrenheat hydronic one. My old unit was 240v using 2 conductors plus bare ground wire. The fahrenheat (PLF series) unit's instructions...


Hello. The red and the black are the hot wires. Therefore, connect one of your conductors to the red and the other conductor to the black. Use wirenuts. The bare ground wire should be solidly attached to the new unit's green wire using a wire nut.

I have the Fahrenheat Model FUH 724 heater. The manual states that it can be wired as a 240v 7500W unit but the directions and the unit itself only allow for three wires to be connected Black, White, and...


1st you will belucky if you actually have 240 v, most
homes are usually 220v. In youyr case you need to start at the breaker panel.

This is an example:
You have a Double Pole Single Throw breaker. Black
Wire is hot and goes into one side of breaker,if you havea red wire that goes into the other have of the
breaker.

The white wire ties in the nuetral bar and the bare wire into the ground bus bar. At the unit you hook up the red and the black wire which will supply the 240
Volts, you could tie the white and the ground wires together into the grounding terminal

You should have the black going to 1 breaker, and the white going to an adjacent 2nd breaker.

Check that you have 240 VAC to the thermostat, and that the breakers are fully set.

If you have 240 VAC to the stat, check that 240 VAC is being powered to the heater.

Let me know what you find. (I am assuming the heat strips are good.).

Not sure hooked up correctly


The black and white wires should both go to the breaker. Not just the black wire. If you hook only the black wire to the breaker then you are only feeding the unit with 110 instead of 220. Both wires need to be hot.

Wiring for baseboard heater


I hope you are using a Line Voltage Thermostat!! First, make sure that the power feeding the thermostat is coming from a two pole breaker of the correct amperage (20 amp). If you are using 12-2 wire with ground then please mark the white wire with black tape at each end to identify it as a HOT power source and not a Neutral wire (which is a grounded lead). Do the same for the 12-2 wires feeding the baseboard heater from the Line Voltage Thermostat. The wires from the thermostat (One Black & one White w/black tape) will be wired to each one of the two wires (one Black & one Red or two Black wires) at the baseboard heater. It doesn't matter which wire from the thermostat is wired to which wire at the heater, just as long as there is one wire to one and one wire to the other.(eg. Black from stat to Black at heater/White w/blk. tape from stat to Red at heater OR Black from stat to Black at heater/White w/blk. tape from stat to OTHER Black at heater). I have seen baseboard heaters with two black wires or one black and one red wire. Hope this helps, but if you are confused then please have an experienced tech. do it for you.

Properly installed electric baseboard heater won't work.


I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.

To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.

If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.

Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.

How to wire 1 plf 1504d heater


I have the solution, finally after looking for 2 days.

First off, I couldn't quite put it all together based on what I was reading. I finally tracked down the Fahrenheat web site (www.fahrenheatpro.com). And called tech support (800) 452-4179.

To wire 2 BB units to 1 tstat.

1. Use #14 wire for 0-12 amps, #12 wire for 12.1 to 16 amps and #10 wire for 16.1 to 24 amps.

2. I have a 12/2 wire going from the tstat to BB#1 and another 12/2 wire going from BB1 to BB2.

3. Onthe left side of the heater, you will have 2 sets of black wires tied together with a nut (on right side it's 2 sets of Black/Red wires). You can use either side of the heater. For the purpose of explaining this, lets use the left side, 2 sets of black wires.

4. Undo one of the sets of black wires (it doesn't matter witch), the other set will be left alone.

5. Take the black wire coming from the tstat and tie it into one of the black wires from the heater and the black wire going to the second BB unit. So you will have those 3 wires tied together with a nut at the 1st BB unit.

6. Take the white wire coming from the tstat and tie it into the other black wire from the heater and the white wire going to the other BB heater. Again, you will have 3 wire tied together here.

7. At the second BB unit, tie the black wire coming from the 1st unit to one of the black wires in one of those 2 sets of black wires. Again, only undo 1 set of wires at the 2nd unit, leave the other one alone. Tie the white wire coming from the 1st unit to the other black wire.

8. Make sure ground wire in grounded at the tstat and at both BB units.

Hope this helps...... If I was less clear than I hoped, call tech support and they will walk you thru it....

Kevin.
