Does 240 volt have a neutral wire?

Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.


Is red or white neutral for electrical work?

In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.


Is France 110 volt or 220 volt?

France uses 220-240 volts for their electrical system.


What is more efficient to run a pool pump on 120 Volt or 240 Volt?

How can you get 277V from residential service?

1You could get 220-240V from using the two live ["hot"] wires rather than one live and one neutral. 2Tim, Industrial control transformers are available to get 120 volts from 277 volt systems. If you feed one of these with 120 volts to the secondary coil, it will put out 277 volt from the primary. However, these are rare and are not cheap. If you are trying to use surplus 277 volt fluorescent lights on a 120 volt system, it would be cheaper to replace the ballasts in the fixtures. Another approach would be to use an autotransformer with a 240 volt primary and a 32 volt secondary. If you feed it with 240 volt and wire it to boost +32 volts that will give you 272 volt which should run the lights. But again, you are looking at $60 - $100 for one circuit of lights. 3If you have access to three phase power..... Phase to ground on a 480v 3 phase system is 277v.

How do you size the neutral in a 240 volt system?

On a 120/240 volt distribution the neutral is sized along with the supply conductors. The sizing is based on the amperage of the service distribution.

If a receptical outlet doesn't have neutral wire where is my problem?

The receptacle that you are looking at might be a 240 volt receptacle and that is the reason, there is no neutral needed. You should be able to tell by the configuration of the blade pattern if it is rated for 240 volt operation.


Where do you attach the neutral in a 240 volt switch?

Unless the switch has a pilot light on it there is need for a neutral connection to the switch.


Is it 110 or 220 Volt electricity in Hawaii?

Throughout the USA the normal supply voltage is 120/240 v in a split-phase 3-wire system using a neutral and two lives with 240 across the live wires and 120 v from either live to neutral. Appliances up to 1500 watts operate on 120 v and, above that, 240 v. 208 v three-phase is also used, which has 120 v from any live wire to neutral. Larger users can get 480 v three-phase, with 277 v between live and neutral.


Can a 277 unit heater be supplied with 240 volts?

Absolutely not!! 277 volts is developed from a 480 volt power supply employing 1 conductor and a neutral. 240 volt power comprises two hot conductors and NO neutral.


What size wire for neutral in a 240v 30 amp circuit?

Answer for USA, Canada and countries running a 60 Hz supply service.240 volt two wire circuits loads do not need a neutral to operate. A three wire 240 volt circuit that needs a neutral, will have a neutral the same size as the current carrying conductors. In this case a #10.


Can you run a double phase motor on home 220 volt system?

If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.


How do you switch from 120 volt to 240 volt in house?

Answer for USA, Canada and countries running a 60 Hz supply service.To operate a 240 volt load in the home you use two adjacent breakers. This will give you a voltage of 240 volts where as one breaker to neutral will give you 120 volts.


Can you use 240 volts with a 120 volt supply?

Only if the cable going to your well pump is a three wire. The third wire could carry the neutral and you will have 120 volts from either 240 leg to the neutral.


Can you use 240 volt 3 phase to run a machine that is 240 volt single phase?

Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
