Connect black wire to heater to other connection on thermostat. Connect ground wire from panel to junction box then to wire nut, with ground wire to second junction box and to heater. In the second junction box with the second thermostat, connect black wire from first junction box to thermostat.
Can you put 2 baseboard heaters on the same circuit?
You can either do that by connecting each heater to the thermostat directly, or by connecting each heater to the next — just be sure that each heater is connected to the source wires. (You can also check out the wiring diagram at the top of this post — it shows how to wire multiple baseboards together.)
Can you daisy chain electric baseboard heaters?
In most all cases, multiple baseboard heaters can be connected together if the total operational amperage does not exceed the wires and circuit breaker’s capacity. If the heater is too large it must be wired on a separate circuit.
How many heaters can I put on one circuit?
A circuit running on a 20-amp double-pole breaker can have any combination of heaters up to 3,840 watt. You can install two 1,500 watt heaters if you use just one thermostat. There are three 1,000 watt heaters.
How many baseboard heaters can I put on a 20-amp circuit?
If you use 240V baseboard heaters, the 20-amp circuit can support a net total of 4,800 W. That’s two 2,000 W baseboard heaters or three 1,500 W baseboard heaters. In short, a 20-amp circuit can handle anywhere from 2,400 W to 4,800 W of baseboard heater electric power input.
Does a baseboard heater need a dedicated circuit?
240-volt baseboard heaters are in need of a dedicated circuit to supply enough power for proper functionality. The general rule of thumb is that baseboard heaters need a 20-amp circuit that requires a 12-gauge wire for either type heater.
How do you wire two heaters in parallel?
Connecting the heaters in parallel means that essentially the two wires coming from the power source (the thermostat) go to the two ends of the first heater, and the same two wires then continue on and are connected to the two ends of the second heater as well.
What size breaker do I need for a baseboard heater?
Electricians generally install 240-volt heaters, since they use lower amperage and are more energy-efficient than 120-volt heaters. Adding a 240-volt baseboard heater usually requires a new 20- or 30-amp double-pole circuit breaker and new circuit wiring to supply one or more heater units.
Can wires touch baseboard heaters?
Electrical codes typically do not prohibit installing heaters below wall outlets, but most heater manufacturers recommend against it. The concern is that a cord plugged into the outlet will drape down onto the heater.
How do you wire a thermostat to a baseboard heater?
Quote from the video:
Quote from Youtube video: Heater. Next connect the white supply wire coming from the circuit breaker to the same color supply wire feeding to the baseboard. Heater carefully tuck all wires into the wiring compartment.
What is double pole breaker?
Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there’s a short circuit on either of the poles’ hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC’s circuit.
What is a 2 pole 20 amp breaker?
A double pole breaker is primarily used with a 240-volt circuit, 20-60 amps and consists of two hot wires. The circuit breaker, the wire and the wire insulation are all designed to work together as a system.
Do electric heaters need to be on a separate circuit?
The National Electrical Code requires that all major appliances have dedicated circuits. Major appliances include refrigerators, stoves, washers & dryers, and some space heaters. Space heaters can range from 400 to 1500 watts, but a good rule of thumb is that the maximum watts per outlet should never exceed 1500 watts.
What size breaker do I need for a 1500 watt baseboard heater?
A 1500-watt heater on a 120-volt circuit thus needs a breaker of 15.6 amps. Because a 15-amp breaker would be too small, you need a breaker with the next highest rating, which is 20 amps.
How many amps does a baseboard heater use?
Manufacturer’s Recommended Heating Needs
| Total Area of Room (sq. ft.) | Recommended Heater Rating (watts) | Electrical Circuit Size Needed (240 volts) |
|---|---|---|
| 300 | 2700 | 15 amps |
| 400 | 3600 | 20 amps |
| 500 | 4500 | 30 amps |
| 800 | 7200 | 40 amps |
Do I need a single or double pole thermostat?
Quote from the video:
Quote from Youtube video: For a double pole thermostat you will have four wires two lines and two loads. The difference between these is that single pole thermostat doesn't have a true off setting.
How many watts can a 20 amp breaker handle?
Now, a 20 amp breaker generally can support 2,400 watts per single circuit.
Why is 240V better than 120V?
At 240V the amperage is 50% of what it is at 120V. So, by using 240V you are able to take up less space in your electrical panel, and allow more room to make any future modifications which involve electricity. It also requires less wiring and you can fit more heaters on a 240V circuit than you can on a 120V circuit.
How do you tell if a circuit is 120 or 240?
Turn off the power to your thermostat before checking the wiring as high voltages can be dangerous and even fatal. You can also look into the gang box of your existing thermostat. If you have black and white wires you likely have 120V. If you have black and red wires you likely have 240V.
What cost more to run 110 or 220?
A quick answer: Probably nothing. This is a common misunderstanding about how electricity works and how the power companies charge you for it. The point often noted for the money saving argument is that the amperage is half as much when running grow lights on 220 volts instead of 110 volts.
