2 x 120 volt wiring from one 220 volt wire


I have a 12-3 Romex wire that uses only the red, black, and ground wire to run a 110 volt baseboard heater. it is wired to a 20 amp breaker. Can I use the left over white and join it to the existing black to run a seperate 110 volt plug?

something is wrong. The white should have been used along with one of the colors for the power IF it actually is a 120 volt heater. Do the wires actually land on a single pole breaker and the neutral bar in that panel?

how did you determine it is a 120 volt heater?

The red & black wires run to oposite end of the heating element. The red wire is connected through what looks like a resistor but I'm not sure about that. The white wire is capped off with a marette. The breaker is a double breaker marked 20 amp and there is a neutral bar in the breaker box. The heater is not marked, it was my assumption it was 120 volt. It does not work but I was going to replace it at the same time wiring it the same way it was.

that is a 240 volt heater. the 2 pole breaker is what gives tells me that. If the heater is totally self contained, there should be a thermostat on one end or the other of the unit.

If the OP is from Canada if he have red loomex { NM } cable then it is stragiht 240 volts due there is no netural in the cable but if he have legit 4.0mm˛ Triplex NM (12-3 ) then he should netural in there but he have to double check the load centre to make sure it is connected.

Normally most baseboard heater are delicated circuit however watch out some case you will have few baseboard heaters on same circuits.

Merci.

A full off postion mean that is double pole thermost I have ran into like that few time and the thermostat will have 4 conductor on the thermostat but for the incomming and outgoing conductor or cables you will see single incomming and maybe multi outgoing cables some case two few case three cable but two is most common I know of.

BUT turn off the breaker first before you yank it out anymore on the wall thermost due there is live connection on the termosat { back side } and one wrong move and short it out you can destory the theromosat quick.

I have checked all the connections with a meter and both the red & black coming into the thermostat are hot. The white is capped at both the thermostat and at the breaker box so it is not used at all. The bare ground wire is connected. The two wires coming from the thermostat to the heater are both dead withe thermostat off and both hot when it is on.

What I want too know is if I use either of these hot wires and connect the neutral normally through another breaker, can I do this for an outlet?

IMO it will be not a wise idea to run a receptale on the heater circuit all it depending on how many wattage the heater circuit is on now.

Quick tip 250 watts per foot is normal but few may have lower wattage rating so count the numbers of heater you have on that circuit and mesure how long the baseboard heater and use my tip to get the wattage.

Don't be suprised if you see at least 2,000 to 3,500 watts on that circuit.

Merci.

That is 1500 watter .

Just hang on I have to dig up the codes and one of the other electricians will chime in here to confirm if that allowed to do that.

{ I know in France we can't do that for safety reason }

Merci.
