How do you wire a 240 volt baseboard heater?

Instructions

1. Install a Wall Box for the Thermostat. Make a cutout for the line-voltage thermostat and install a wall box.
2. Run Cable for the Circuit.
3. Mount the Baseboard Heater.
4. Make the Wire Connections at the Heater.
5. Make the Wire Connections at the Thermostat.
6. Connect the Circuit Breaker.
7. Test the Heater.

Do 240v baseboard heaters need a neutral?

Straight 240 volt equipment does not require a neutral because they do not need the 120 volts provided by a 120/240 volt circuit.

Where does the red wire go on a baseboard heater?

Locate the red wire(s) on the ther- mostat. These are the L1 and L2 and attach to the power supply. The black wire(s) are the load side and attach to the heater. Attach one red wire from the ther- mostat to the white wire from the power supply with a wire nut.

What wire is needed for 240v?

Before You Start Also, make sure the amperage of the breaker matches the amperage of the circuit wires and the appliance being powered. A 20-amp 240-volt circuit calls for 12-gauge wire; a 30-amp circuit calls for 10-gauge wire; a 40-amp circuit calls for 8-gauge wire; and a 50-amp circuit calls for 6-gauge wire.

How many 240v baseboard 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.

How many wires are needed for 240V single phase?

In the case of 240V, the circuit requires 2 Hot wires. One Hot wire from each ‘out of phase’ busbar is required to complete 240Volt circuit. These wires can be Black and White or Black and Red, and with heavier gauge wires, like 6 gauge and 4 gauge, the wires are Black and Black.

How many 240V baseboard heaters can I put on one circuit?

How do you wire a baseboard heater?

For standard baseboard wring on the right or left 120V or 240V supply.

1. Connect one supply wire to one heater wire.
2. Connect remaining supply wire to remaining heater wire.
3. Replace wiring compartment cover and secure with screw previously removed.
4. Turn power back on at the electrical panel board.

How do you wire multiple baseboard heaters?

You must wire heaters in parallel, not series when using them with one thermostat. All heaters must be wired in parallel. 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.

What wire do you use for baseboard heaters?

A 12-gauge wire is typical in many homes, and it is larger than a 14-gauge wire and smaller than a 10-gauge wire. Generally, 10- to 12-gauge wire is what you see in most homes and is what would be used for baseboard heaters.

To wire a 240-volt baseboard heater, connect the two insulated wires of the heater to a two-pole 20-amp circuit breaker, and connect the bare copper wire to the ground buss. To indicate that the white wire is live, wrap it with a black or red tape before attaching it to the breaker.

What is the best brand of baseboard heaters?

Cadet is probably the best brand that makes electric baseboard heaters. It consistently produces high quality heaters that not only rank highly in terms of ratings but also get high reviews from the people that have tried them.

What size wire for a baseboard heater?

Typically the baseboard heater circuit wire will be provided by installing a 2-wire cable with a ground, and the colors of the insulated wires will be black and white, and the white wire of a 220 volt circuit is typically colored red.

How do you replace an electric baseboard heater?

To replace a baseboard heater, start by turning off the appropriate breaker in your circuit panel. Next, pull the wires from the panel and cut them, then twist them together and attach a plastic wire cap. Remove the heater’s cover and cut the power wire there as well, then unscrew the panel from the wall.
