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.

How do you put on a four prong outlet on a roper electric dryer?

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


Where do you connect the white wire from the shunt breaker?

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


How does a phase leg connect to a neutral in an electrical circuit?

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


What happens when neutral and phase of a electric connection gets inter changed?

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.


Does 3 phase need a neutral?

As far as I understand, you don't need neutral line for connecting appliances that is 3-phase compilant. You only need the neutral line to connect a single phase appliance, which you connect along with one of the three lines.


Why can you touch a neutral bar?

Neutral would refer to some object or circuit which has the same electric potential as the relative object. A "neutral bar," would mean a conductor which has no electric potential. If your body has no electric potential, then the potentials will equal, and no energy will be transferred.


How do you connect wire to a breaker?

If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black &amp; white wires to the breaker, &amp; ground wire to the ground bar.


Why supply circuit breaker should be 4poles?

Because it has neutral with 3 phases. A supply circuit breaker is used on the lv side of the transformer to protect the equipment connecting to it.


How do you wire a 120V circuit off a 240V circuit?

In a 4 wire, 220v AC circuit, each black wire carries 110v, the white serves as the return, or negative, and the copper is the ground. So connect the white to the negative post of whatever your using (light or switch), and one of the black wires to the other for a 110V circuit. If you're connecting a 110v two- strand wire to a 220v outlet, connect one wire to a black post and the other to the white post. Make sure you have a neutral. Some times the white wire is the second hot and there is no neutral.


What is meant by an open circuit and short circuit?

Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)
