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.

SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Black & 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. <<>> Potential danger to users of that circuit.
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.
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.
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 & white wires to the breaker, & ground wire to the ground bar.
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.
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.
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:)
A Neutral, Common, or Ground.
No, not without a load being between them. A direct connection will create a short circuit and the circuit protection will open the circuit and stop the current flow.
remember the + side of the speaker basically means neutral, in all electric projects the - is always the live line, so if + means neutral that basically means that ground would also be neutral, speakers dont need ground, so if u wish connect + with neutral on the speaker.
I think you probably mean 'lines', rather than 'phases' but, even so, your question is still confusing. However, if you connect any two lines together directly, you will create a line-to-line short circuit fault; if you connect any line and neutral together directly, you will create a line-to-neutral short circuit fault.
You connect the fuse to the live wire as it is the one with the potential difference of 220V and in case of short circuit current will blow out here
I would think not. However, if live were to come into contact with either the ground, or the neutral or both, this would cause a breaker to trip.
Take two electrical devices that require the same voltage potential. Connect the two hot wires together. Connect the two neutral wires together. Apply the required voltage to the two tied together ends. Now these two electrical devices are operating in parallel.
Two wires are hot and are usually Red and Black. Connect the white wire to neutral and green wire to ground.
The Neutral is used to bring power back to the source to complete circuit
If the 3 phase service has a 4th wire (neutral), then yes, just connect one of the three phase wires and neutral for a single phase circuit.
A multiwire branch circuit is consist`of two or more ungrouded conductors that has voltage between them and has a grounded conductor that is eoual voltage between each conductor connect to the neutral and it,s ground
Answer for USA, Canada and countries running a 60 Hertz supply service.The grounding electrode conductor is brought into the main disconnect section of the distribution panel and a connection is made to the neutral block. The terminations in the panel at this point are two incoming "hots" to the main breaker and a neutral wire to the neutral terminal block. In the neutral termination block there is a ground screw that screws through to the distribution panels metal enclosure, there by making the metal enclosure the same potential as the ground plate or rods and the neutral wire that comes in from the street. The grounded circuit conductors of the wiring system are terminated on a separate ground buss that is located in the circuit breaker section of the panel. This buss is bolted directly to the rear of the distribution panel's metal enclosure in the circuit breaker section of the distribution panel. This ground buss is at the same potential as the ground electrode conductor above because of the grounding screw that connects the neutral block to the metal enclosure. Code requires when wiring sub panels within the same building that the neutral block screw be taken out of the circuit and a separate ground wire be run directly from the main distribution panel. This is to prevent any short circuit currents from the sub panel traveling back on the sub panel feeder's neutral wire.>In house wiring you have earth ground connect to the ground bus in the main electric panel. Your neutral bus is "bonded" to the Ground bus only at the main panel. When you run branch panels you do not connect neutral to ground in these branch panels, only the main panel. There is typically a screw in an electric panel where the bonding occurs.
On a pure 240V circuit, no. There is no neutral. On a 240/120V circuit, yes. You have the needed neutral. Tapping 120volts off an existing 240volt branch circuit with a neutral is possible but is not a proper method. It does not comply with most electrical codes.
