European domestic supplies are 230v single-phase, derived from a 400 v three-phase supply running down the street (usually underground). This supply is a 4-wire system with three lives and a neutral, which it must be because the different properties draw different currents.
When the system is working well the current drawn by a group of houses are reasonably well balanced across the three phases.

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
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.
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.
