This is a dedicated circuit that serves only the heater s.
Wire 240 volt baseboard heater thermostat.
The heater has two red wires.
Always turn off power at the circuit panel before attempting any electrical work.
Typically this is marked l1 or line step 8.

The 240 volt baseboard heater may only be connected to a 240 volt supply with a double pole circuit breaker in the electrical panel.
Both of these service wires come in the panel together with a ground wire typically the ground is a whole lot of strands that surround the hot wires.
Thermostats designed to operate 240 volts heaters have two hot terminals each accepting one standard 120 volt connection.
See the specifications for the brand that you are considering.
Baseboard heaters work especially well with a 208 240 volt circuit which provides a balanced load compared to a 120 volt circuit.
It s a non programmable thermostat that s simple to use.
Electricians generally install 240 volt heaters since they use lower amperage and are more energy efficient than 120 volt heaters.
If you are wiring a 120 volt baseboard heater however the white wire in the circuit will be a true neutral wire.
Baseboard heater electric wiring.
Using a wire connector connect the hot supply wire to the thermostat wires.
Electric baseboard or wall heaters and their thermostats should be wired to their own dedicated circuit to prevent overloading.
Whether the thermostat is being wired as a single pole or double pole both the black and white wires are hot in any 240 volt circuit.
The breaker is a double so i assume i need to connect white and black 12 2 wire to the two poles on the breaker and the copper to the ground screws on the panel.
Connect the remaining thermostat wire typically marked t1 or load to the same color supply wire feeding the baseboard heater.
A 240 volt thermostat doesn t use neutral wires and as such all wires are hot.
A neutral wire isn t utilized within this circuit.
Failure to meet proper electrical standards can result in electrical shock or fire.
I am trying install a 240 volt wall heater with a built in fan to a thermostat.
