first off. it has to be UF type wire, and is usually 12 gauge or 10, depending what you are using it for.
A #6 copper wire with an insulation rating of 90 degree C is rated at 65 amps.
8/3 with ground.
The current will remain in a 220 volt circuit as long as the circuit load remains in the circuit and the circuit remains closed.
A #3 copper conductor will do the job.
Yes, in the form of GFCI circuit breakers, not as a receptacle.
No, not a good idea. You have to use a 347 volt ballast.
8 gauge will be sufficient with less than a half volt drop
# 3 gauge
Use 8 gauge wire.
A volt can not be connected to a circuit.
A 20 amp 240 volt circuit can provide 4800 watts.4800 watts / 6 watt per foot = 800 feet.
The wire size depends on how much current it will conduct.
The current will remain in a 220 volt circuit as long as the circuit load remains in the circuit and the circuit remains closed.
A map of a circuit is not a volt. A map of a circuit is referred to as a schematics chart. The schematics chart details the path of the circuit, from beginning to end.
It depends on the use it is being put to. It is sufficient for a 24 volt circuit. Too much for a 12 volt circuit and too little for a 240 volt circuit.
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
NEC 220.52(A) & (B) state that an additional load of not less than 1500 volt-amperes shall be included for each two-wire small appliance circuit and each laundry circuit.
Not enough information. To answer this question the amount of current in AMPS the circuit is drawing is needed.
A #3 copper conductor will do the job.
