Install and hot wire heater

I need to install a used fan forced room heater. I don't know the correct wiring sequence to my power source. It is a 240/208 volt. It has two loose black wires, one from the temp control and one from the fan motor. also, a green wire that connects to the fan motor. No loose white wires visable.

    Does the taped white wire in the heater also connect to one of the black wires in the heater and, if so, which one or does it not matter?

Go to Look under their wall heater section. Download the instruction manual for your model (or one closest to your model).

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.

    when you run 240 volts to a heater, it is more practical to use a 2 wire romex rather than a three wire which has red, black and white in the assembly. you just don't use the white in the three wire - so - by applying a piece of tape to both ends of the white wire in the 12/2 romex, you are signifying to someone other than yourself that that cable assembly is carrying 240 volt - NOT - 120 volt. If there was no tape on the white then as an electrician I would assume that the cable is connected for 120 volt. Do you understand this? Use the tape on both ends of the romex [white] connect both wires in the 12/2 to the breaker screws. connect the other end in the heater to the two black wires and the bare to the green. Believe me, if you measure the voltage at the heater end, with the breaker on, you'll read 240 volts.

My 30000w fan forced ouelette heater runs but does not heat

Did you ever get this issue resolved?
I just purchased a Ouellett 5000w heater, it runs fine, but does not seem to get very hot at all. I checked and the voltage and current are correct. If I pull the fan wire off, the elements get red hot within one minite, as soon as I re-hook the fan up the elements start to cool. yet the voltage and amperage are still correct (20.5a 240v)

Coleman evcon electrical furnace doesnt force air intermittently

It sounds like the fan is not functioning. With the breaker, SSU, and/or power off check the wiring, tighten any loose wiring, and make sure nothing is blocking the fan from spinning. Check to see if it will spin by hand, if there is access. If it does, and you have power, then the fan motor may need to be replaced.

Does this help? Let us know.

I mean this respectfully, if the technician cannot wire a unit without a wiring diagram , he is not competent to do the work.
It is really very simple, If you look at the power lines entering a building, ther are but 2 hot legs of 115 volts for 230 volts and a earth / ground, every wire we will ever see are these 2 hot legs or a combination of them.
Every circuit requires 2 sides/legs of power, a device and a switch, begin at L1 go through switch to load return to opposite side of power from where you began, very simple.

If you do not know this a wiring diagram will tell him nothing but how to blindly try to follow some diagram he has no grasp of the theory behind or he would see how simple his dilamna is.

Sounds like you have two hot wires. Just need to find out which wire goes to the wall switch. Try gray to black from fan,pink to black/white wire.white to white & green to green. If this doesn't work swich the pink & gray wires.

Connecting lighting correctly

Don't know what you're working with.

AC household electricity?

Common (White) wire goes to all three lights. Goes to silver colored screw.
Hot (Black) wire goes to switch, then all three lights.

ALWAYS put the switch in the hot wire. Not the Common.
Let's say you are changing a light bulb.
Your feet are on the floor. You are then considered to be Grounded.

You have the light switch off. You go to remove the light bulb, slip, and a finger goes in the socket.
You get shocked.

Hot (Black) wire has the switch. This time of you slip, and a finger goes in the light bulb socket; you won't be shocked.
The power is turned off at the switch.

Common wire comes from source. (Service Panel/'Breaker Box'), and goes to the lights.
Hot (Black) wire comes from source, and goes to light switch.
Then to the first light, second light, and third light.

Is there a 3-way switch involved?
Walk in one end of the room, turn the light on, walk to the other end of the room, and turn it off?

Post back in a Comment as to the exact query.

I have a ceiling fan switch (Westinghouse 77075) that was broken, so I do not know where the wires (black, gray, yellow and purple) went. The speeds are black+gray+yellow, black+gray+purple, and...

I can offer resources:

1) Test switch that was removed, and test for hot connection to narrow down options.

What speed was fan stuck in when switch was removed? Let's say medium speed.
Which connection at fan is hot? Use voltage tester to find hot connection at fan, and match that up with wire-color on switch that was removed.
One and only one wire on 3-speed fan switch connects to hot. And the hot wire is the only wire that connects to each other wire as switch cycles through pull-chain sequence. All pull chain switches follow same sequence: off, low, medium, high.
Let's say old switch was stuck in medium, and you know which color wire connects to hot.
Test switch with continuity tester to see which wire(s) have continuity with hot wire: some switches, it will be 2 wires, and other switches it will be 1 wire. Match where wire(s) were connected, and map that to tests on new switch.

2) Open following link for illustrations and some other links.

The switch that you have works like 3 seperate switches. most of these switches will have gold screws
on one side and silver screws on the other side, lets say that the left is gold and the right is silver, and
the switch may also have a green screw for ground. your 12/2 with ground is your main hot, you may
want to mark it with a piece of tape, so you know it's the incoming hot. the ground off your hot will tie,
to the green screw on switch and continue and tie to your vent light which should also have a ground
the white coming off the hot is your neutral, it will go straight to your white or whites on your heater.
the black hot wire at your switch will go to each gold terminal on one side of the switch,there are two
ways you can do this, go to one side and just run a jumper, or put one wire on each gold screw and
tie in to your hot-black wire with a wire nut. now for the switch legs, you will need to run from your, switch
to your heater either another pair of 12/2s or a 12/3, each side of the switch that has one silver screw,
it's easier with a 12/3 normally a 12/3 will have a red,black,white,and ground.
top switch red to red on heater,black to black on light and the white blue on the vent,so from your switch
to the heater you would have to run a12/2 you would not use the black only the white and ground.
remember the white-neutral coming from the switch will be tied to all the whites at the vent,light,heater
except for the 10/3. the 10/3 is used stricktly for the switch legs. good luck!

Need wiring diagram for cadet the hot one heater so i can install new fan motor

You do not need a wiring diagram to replace the fan. TURN OFF POWER.
The fan will have two wires coming from it to two places. Make a little map of that location. There is usually a quick disconnect, you unplug and swap.
