In North America the cable colour coding is Red and Black, usually used for the current carrying conductors. The third wire is White and it is used as the neutral on a three wire electrical circuit.

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.
Why use 3 wire 240 volt receptacle instead of a 4 wire 240 volt receptacle?
Use the 4 wire if possible. You would only use a 3 wire for an old appliance.You shouldn't if possible. The 3 wire has no neutral wire as the 4 wire does. Som applications require the use of a 3 wire and some don't.
When is white wire hot?
In residential wiring, if it is used as a switch leg or in 3 wire 240 volt circuits.
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.
What size of cable wire used for 500 kva transformer 240 volt 3 phase?
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
Is a 220 volt electrical power wire the same as a 240 volt electrical power wire?
Yes 220 & 240 are considered the same.
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.
Can you wire a 240 volt window ac from a 277 volt feed?
no
Will splicing a 3 wire 240 volt compressor with a 4 wire 240 volt male end damage compressor motor?
It could if you don't get the terminals and motor wires on the correct terminals.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
How do you change a 220 240 volt wire to a 110 120 volt wire?
Wire is wire - is doesn't matter what voltage you use. However, if you are changing the voltage on a device from 240 to 120, given the same power requirement, you may need bigger wires for the doubled current (and increased heat of resistivity).
Can you use 600 volt wire for 240 volt appliance?
It depends on the voltage, but if you are using it on a 240 v system, it's quite OK to use wire that can take 600 v (if you had to buy the wire, you would be spending too much).
Will GFCI work properly if 240 volt split into one 3 wire 120 volt circuit?
yes
What wire size for 70 amp service at 240 volt?
4 copper
How do you wire a 120 volt gfci into a 240 volt three wire?
You can't. The 120 volt GFCI is probably just a 2-wire (hot, neutral and ground) You would have to run a new 3-wire (2 hots, neutral and ground). The two hots are how you get the 240 volts (120+120=240). Also you must make sure the wire is gauged properly. #10 wire for 30 amps, #12 wire for 20 amps, etc.
Why use 3 wire 240 volt receptacle instead of a 4 wire 240 volt receptacle?
Use the 4 wire if possible. You would only use a 3 wire for an old appliance.You shouldn't if possible. The 3 wire has no neutral wire as the 4 wire does. Som applications require the use of a 3 wire and some don't.
When is white wire hot?
In residential wiring, if it is used as a switch leg or in 3 wire 240 volt circuits.
