Since it is a 30 amp heater you need to run #10 gauge wire and use a 2 pole 30 amp breaker, since it is 208/240 volts. I hope this helped you.

How to install heater blower motor? I have air conditioner also! it keep blowing a fuse when I replace it and heater will not work at all!


Hello
Most blower motors come with a high or low voltage connections or wiring.So theres 2 options.

You need to be sure of the voltage of the heater 115 v 208 v ?A 115 volt heater needs a 115 v blower.

IF your wiring the blower for 208 and its really 115v your going to blow something.

Thermostat Line Voltage How to Install or Replace


You either have a new line voltage thermostat or have to replace your old line voltage thermostat. In either case the process is much the same.

  1. Make sure that all power is turned off at the breaker panel. Most heaters that use a line voltage thermostat usually use 240v current so the breaker will either be a double pole breaker or you will need to turn off two single pole breakers to kill all of the power.
  2. Check to see which wires are hooked to the breakers. In most cases it will be the red and black wires, but I have seen many times that the white and black wires were used. Often there is no red available when the white is used.
  3. Take out the two screws that hold the thermostat to the junction box. When you get the thermostat out make a note of which wires go to the heater (load) and which wires are coming from the breakers. (line)
  4. If you have a single pole thermostat installed one of the sets of wires may be wired straight through the box or have the line and load wires connected directly in the box. With a double pole t-stat you will have both sets of wires running through the t-stat.
  5. Remove the old thermostat and wire the new t-stat in the circuit with the load wires hooked to the load or heater and the line wires hooked to the wires coming from the breaker. Make sure to get a very good tight connection as resistance loads will heat up quickly if good contact is not made. This poor connection can and will start fires.
  6. Turn the power on and check the heater for heat output.
  7. Turn the power back off and carefully screw the thermostat to the junction box securely. Then you can reapply the power to the circuit.

Now you are up and running with a new line voltage thermostat installed.

If you're troubleshooting HVAC electrical problems

230 volt single phase ac
The Common wire or circuit on an A/C or heat pump never has a run capacitor in that line.
The Run wire always has the run capacitor in that line or circuit.

115 volt ac
The Run or Hot wire has the run capacitor and the neutral wire does not.

So if you are tracing wires out in a circuit, if there's a run capacitor, it's the Run wire or Run circuit.
The Start wire always goes to the opposite side of the run capacitor than the Run wire and it is the only wire on that side of the capacitor.
The Run wire goes to the run capacitor, then goes to contactor, compressor, start capacitor or fan, so there's usually two wires on the Run side of the capacitor.

Wiring schematic, where can I get one? thanks


What in particular are you needing help with?This is a 208-230 VAC 1 or 3 phase strip heating unit that requires and external line voltage t-stat to control the temperature.
They also include auto-reset thermal protection.

What else do you need to know?

I'm trying to install a new Fahrenheat 240/208 baseboard heater and it trips the circuit. The old heater was the same 240/208. I initially thought I had miswired the heater but it tripped the circuit...


Hi!
If the circuit breaker is tripping instantly when power is applied to the heater then you have a dead short somewhere. You need to check your wiring again. Either it is wired wrong or you have part of a bare wire that is touching another wire or to ground. If all your wiring is correct then the element could be bad or is grounding out to the cabinet or whatever. Take another good look at all the wiring. Good luck!

I need A wiring digram for a Byrant 7a4anf036000abaa air handler It is old but still in good shape . I just need to change the transformer an a frind removed the wires and i need to check a digram before...


I have searched high and low for a schematic and that model number doesn't even come up anymore? I have worked on bryant units for years . I can tell you by the 036 , it is a 3 ton unit. as far as replacing the transformer, you may not need a diagram. If you know what the voltage is coming into the unit, lets say208/230 and look to see what your control voltage is by looking at the voltage rating on one of the parts in the system, I would say 24volts, your chances are good you can install the transformer. A new 208/230voltx24volt trans, comes with all of the wiring laied out for you. Find the 2 high voltage Line wires coming in and tie to the high side of the transformer, and the 2 wires labeled for 24 volts to the load side, and your all set.Keep in mind that some of these universial transformers come with several colored wires for different voltages, so be sure to look at the transformer diagram and it will tell you what colors to tie together for the voltage you need. You should be able to pick up where you're friend left off, just look for the high volts in for one side and low volts out for the control side.Be sure to have a meter on hand to check the voltage. Just take your time, you can do this.

Ps It wouldn't hurt to add a 5 amp auto fuse to one of the wires on the low voltage side of the transformer, in case you miss wire it, and it will blow the fuse and save the new transformer.All you need is 2 female spade connectors and a 5 amp fuse.
Good Luck, Sincerely, shastalaker7

Line voltage Tstat installation Dayton D-F79 elctric shop heater


If I understand your post correctly....You state that you are hooking up a 240v heater and towards the end you speak of removing jumpers...W2 terminals..ect. It sounds to me your trying to us a 24v low voltage thermostat instead of a Line voltage thermostat.That's what I'd take a look at.

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.

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

Install and hot wire heater


You can be assured that the element is 240 volt. The fan motor is also rated at 240 volt. the wires you have black - black are the connections you make to the line. Use a 12/2 with ground. Use a double pole 20 breaker in your panelbox. The green wire is the equipment ground - connect this to the bare wire from the 12/2. On the 12/2 cable - there will be two colors, one black and one white. Wrap a couple of turns of black tape on the white wire both at the heater location and on the white in the panelbox. connect the 12/2 to your 2 pole breaker, the black wire and the taped white to the breaker.
