AWG 10.
6 AWG.
As a service entrance wire you need AWG # 3/0 gauge copper.
To answer this question a voltage needs to be stated. Wire is sized by the amount of amperage the load takes. W = Amps x Volts. Amps = 650/ volts.
# 4 copper wire short distance.
AWG 10.
You would need to use a wire size that is rated for at least 40 amps to be safe and to meet the requirements of the air conditioner. A common wire size for this application would be 8 AWG copper wire, which is rated for 40 amps.
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
6 AWG.
Cable sizing is based on load amperage. The formula you need to use is Amps = Watts/Volts. Amps = 1000/220 = 4.55 amps. A #14 copper wire with a insulation factor of 60, 75 and 90 degrees C is rated at 15, 15 and 15 amps respectively.
The appropriate wire size for a circuit requiring 60 amps is typically 6-gauge wire.
10 gauge
As a service entrance wire you need AWG # 3/0 gauge copper.
The appropriate wire size for a circuit that requires 30 amps of current is typically 10-gauge wire.
Use AWG # 3 copper.
To answer this question a voltage needs to be stated. Wire is sized by the amount of amperage the load takes. W = Amps x Volts. Amps = 650/ volts.
Almost any size wire will handle the 4.2 amps. BUT...as with any wiring, you must look at the over current device to determine the proper size. You need to determine which fuse in the fuse panel protects that circuit and use a wire that is appropriate for that size fuse.
