Can you safely connect a 240V electric heater to 120V service by connecting the red wire to the neutral branch of the circuit?

for USA, Canada and countries running a 60 Hz supply service.

A purely resistive 240 volt heater [baseboard unit] with no fan will operate when connected to a 120 volt source.

Either of the two "hots" in the heater can be connected to the 120 volt grounded circuit conductor [neutral].

The wattage output will be only one quarter of the rated watts, so it won't get mad hot, but it will work.

A 2000 watt 240 volt baseboard heater unit [typically 8 foot] will only allow enough current to generate 500 watts at 120 volts.

If the heater has a fan, then it won't work, because the fan motor won't operate correctly at the lower voltage.

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.

Black &amp; Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.

Connect to the circuit neutral wire which should also be white.

A phase leg connects to the neutral through the connected load.

If the neutral and phase wire of a electric connection gets inter changed it will create a dead short circuit. The fuse or breaker that is protecting that circuit will disconnect the fault from the circuit. &lt;&lt;&gt;&gt; Potential danger to users of that circuit.
