This is wiring 2 baseboard heaters with a double pole wall thermostat
you run the power wire to the thermostat on the wall then you run a wire to the 1st heater and then you run another wire from the 1st heater to the 2nd heater and hook red on red and black on black with wiring mariette's in the heaters junction box on left or right side which ever is more suitable for you and then you go to the wall thermostat and hook red on red and black on black with the wiring mariette's and then you hook your power wire to the power supply which is 100 or 200 amp service and on a double 20 breaker and the wire has to be no smaller than 12/2 wire. also do not forget to hook the ground wire (bare copper) on the green screw on your heater and in the thermostat box and then on the power supply box..... now you can turn up your thermostat and enjoy the heat ...........LEE48

What is the difference between single pole and double pole thermostats?
A line thermostat on a 240 volt heater must open both of the supply lines that feed the heater. This is where the double pole thermostat is used. On 120 volt heaters only one hot line needs to be opened to shut the supply off from the source therefore a single pole thermostat is used.
What is the difference between a single pole breaker and a double pole breaker?
Courtesy of Ace Hardware - I found it on their site · What is the difference between a double pole and a single pole thermostat?Single pole thermostats breaks only one side of the power line to your heater and cannot be turned off. Therefore, power is continuous to the heater even if it is not running. The control knob will have a low temperature setting without an off position. Single pole Thermostats uses only two wires. This means that even if the temperature dial is turned all the way down, voltage is still going into the heater through one line. This may pose a hazard to anyone who might perform electrical work on the heater without realizing that the circuit was still on. You will need to turn off the power at the circuit breaker before electrical repairs can be made safely.Double pole thermostats breaks both sides of the power line; therefore all power to the heater is interrupted. This acts as a safeguard for people performing electrical work on the heater. However, to be on the safe side, you should always turn off the power at the circuit breaker, not at the thermostat, before making any electrical repairs. A double pole will uses four wires and has a off position on the thermostat.Since they are inherently safer, you should always try to use double-pole thermostats, if possible. Another advantage of a double-pole thermostat is that you can turn it completely off and the heat will not come on no matter how cold your room gets. But with a single-pole unit, the thermostat will turn the heat on even if set on the lowest setting.CHECK YOUR LOCAL CODES FOR BUILDING REQUIREMENTS IN DETERMINING IF YOU NEED A SINGLE OR DOUBLE POLE THERMOSTAT BEFORE PURCHASING OR INSTALLING. How can I determine if I have a single or double pole thermostat?Usually, you can tell the difference between a single pole and double-pole thermostat by looking at the dial. A double-pole normally has an "Off" position on the dial whereas a single-pole thermostat does not. The only sure way to tell which kind you have is to remove it from the wall and count the wires connected to it. A double-pole thermostat will have four wires that switches both hot wires whereas a single-pole thermostat will have two wires that only switches one of the hot wires. Can I use a single or double pole thermostat with a 120, 208, or 240 volt heater?Yes. Can I use 1 thermostat to control more than 1 baseboard heater?Built-in thermostats (mounted directly on baseboard) are designed for single heater use. However, it is possible to control more than 1 heater on a wall thermostat if the thermostat rating is not exceeded. Can I mount the thermostat on one side and wire the baseboard heater on the opposite side?No, the thermostat requires power from the supply wires and must be wired in conjunction with the baseboard heater. Is a built-in or a wall mount thermostat better?A built-in control is convenient when the walls are already finished. The built-in thermostat is also convenient to install. However, the wall thermostat is a more accurate way to control the room temperature, is more convenient to use, and has a broader selection of models. The use of electronic thermostats provides more accuracy and saves you money on your electric bill. Can all of the heaters in my house be controlled by one thermostat?There are many benefits to zonal heating. Zonal systems save energy by not heating unoccupied rooms and provide the ultimate in comfort by allowing occupied zones to be heated specifically to individual needs. The purpose of each zone's (room) heater is to heat that specific zone per the set point of the individual thermostat. What is the difference between a low voltage and a line voltage thermostat?Low voltage thermostats should be used when the heater load is greater than 3,800 watts such as commercial heater or central forced air systems.Line voltage thermostats should be used for zonal heat systems such as electric fan heaters, baseboard heaters and radiant heaters. What should I do if my wall thermostat feels hot to the touch?Cadet recommends you replace the thermostat. A hot thermostat indicates that it is not working efficiently; decreasing its accuracy. NOTE: A normal operating thermostat will be slightly warmer than the room temperature by 3 to 5 degrees. Can I use a wall mount thermostat to control my heater if it has an in-built thermostat?Yes, to bypass the in-built thermostat, turn the thermostat on the heater to the highest setting, then use the wall thermostat to regulate the room temperature.
What is the temperature of the low setting on a single pole electric baseboard heater thermostat - I realize there is no specific answer but can you count on it being above freezing?
Yes you can count on the settings being above freezing, 0 degrees C or 32 degrees F. On a standard thermostat that controls baseboard heaters the low setting is 10 degrees C or 50 F. and the high setting is 30 degrees C or 86 F.
How do you know what the voltage of your electric baseboard heater is if there is no label on the heater?
Go to your power panel and look for two pole breakers. If there are any 20 amp two pole breakers there is a good chance that they are for the baseboard heaters. Switch this breaker off and turn your thermostat up. If the baseboard heaters do not come on and get hot then this is the supply for them. A two pole breaker is supplying 240 volts to the heaters. Most likely there will be more that one heater on the circuit. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Double pole or single pole hot water heater thermostat?
Single pole.
How do you wire a single pole built in thermostat to a baseboard heater while feeding power to another thermostat?
Split the feed circuit (inside a junction box) and feed the hot to both the baseboard heater with the built in thermostat AND to the 2nd thermostat. If you have any questions, contact a local, qualified electrician, heating specialist or local handyman.
Can you use 12-2 and a double 20 amp breaker to run a basebord heater rated at 4.2 amps and the thermostat rated at 17 amps?
Answer for USA, Canada and countries running a 60 Hertz supply service.The thing to consider here is the current rating of the baseboard heater. If the baseboard heater is 240 volt then yes you would need to use a two pole breaker. If you are using just one heater on the circuit, the current rating of the heater is low enough that you could use a two pole breaker rated at 15 amps and copper wire rated at #14 . The rating of the thermostat is the maximum that the stat will handle safely. With the combination you suggest you could run a total of 3800 watts of baseboard heaters. In amps this would be 16 and well within the rating of the stat.
Is your baseboard heater using power when a single-pole thermostat is set to low?
Your thermostat is just a temperature switch. A switch just breaks the circuit to stop the current from flowing. When you set a position on the thermostat you are telling the switch when to come on and when to shut off depending on the room temperature. If it is set to low then the base board heater will not come on until the low set-point is reached. When the room warms up to above the set-point the baseboard heater will shut off. If your concern is about a 240 volt baseboard heater and just a single pole on the thermostat do not worry. Breaking one leg of a 240 volt circuit will stop the current flow and the heater will not operate.
When installing a double pole thermostat should there be any unattached live wires remaining?

Can you use a double pole thermostat to replace a single pole thermostat?
Answer for USA, Canada and countries running a 60 Hz supply service.A double pole thermostat is a line thermostat and not to be confused with a low voltage stat. When the heating load has 240 volts for a supply voltage, both lines from the distribution panel are supposed to disconnect when the thermostat reaches the set point temperature. A single pole thermostat is only used on a 120 volt heater an the return leg from the heater is a neutral wire.A two pole thermostat can be used on a 120 volt circuit but a single pole thermostat should not be used on a 240 volt circuit. The reason being is that on a 240 volt circuit using a single pole thermostat, one "hot" leg doesn't get isolated from the heater and is always "hot" to ground. This is a shock hazard if you are working on the heater and depending on the thermostat as a disconnect from the distribution voltage.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How much electricity can run on 15amp breaker?
Since baseboard heaters come in many different wattages vs. lengths I guess the best answer would be, you can load up to 2880 watts of baseboard heaters on a 15 amp two pole breaker at 240 volts.
How many baseboard heaters can you put on a 2 pole 15 amp breaker?
The question depends entirely on the size of the heaters and the size of the wire used.Select your breaker size and wire gauge according to the wattage. To determine your amperage, divide your power in watts by your voltage. If the voltage is 100 volts and your wattage is 1000 watts, then the amperage draw = 1000 Watts / 100 volts = 10 ampsIf you intend to control a number of heaters, a relay may also be used. The thermostat turns on the relay, the relay controls the heaters. Thermostats are rated for current and voltage. Make sure you are also using a thermostat big enough for your circuit.
