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.


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.


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 do I wire a double pole thermostat in place of a single pole?

Answer for Canada, USA and countries running a 60 Hz supply service.This description is for a line voltage thermostat. It depends on what the voltage of the baseboard heater is. If it is 120 volts the thermostat will be a single pole and that is all that is required, as the neutral wire is not to be opened according to the electrical code.Now if you are replacing the thermostat and all that you have is a two pole thermostat to replace it just use one side of the two pole thermostat. Connect the voltage supply to the top and the heater load to the bottom of the thermostat.Single pole thermostats can also be used on 240 volt installations as only one leg has to be opened to stop the current flow to the heater. This is not recommended as the other leg of the 240 volt supply is still "hot" to ground and you could get a shock if you accidentally touch the other leg and ground.The proper way of wiring a 240 volt heater is to bring the two supply wires to the top of the thermostat and connect the heater load to the bottom of the thermostat.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 JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.

How do you wire a double pole thermostat to two baseboard heaters?

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

first of all you buy a double pole unit thermostat which should come with the mounting plate and thermostat and it should have 4 wires 2 red 2 black okay now you join the red to the red power wire and black to the black power wire and the 2 remaining wires which should be a red and black can be joined to the red and black wires on your heater .....now you should be good to go ............LEE48


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.
