AWG 10.
NEC 310.16 conductor ampacities NEC 240.4(D) For residential installations the smallest wire to be used is 14 AWG (15 amps rating) and for commercial installations the smallest wire to be used is 12 AWG (20 amp rating)
# 4 copper wire short distance.
The V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
6 AWG.
The appropriate wire size for a circuit requiring 60 amps is typically 6-gauge wire.
For a 70 amp service at 240 volts, you would typically use a wire size of 4 AWG copper wire. This wire size is suitable for carrying 70 amps of current safely over a 240 volt circuit. Be sure to consult local electrical codes and regulations to ensure compliance with requirements in your area.
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 appropriate wire size for a circuit that requires 30 amps of current is typically 10-gauge wire.
AWG 10.
The recommended wire size for a circuit carrying 35 amps of current is typically 8 AWG (American Wire Gauge).
The recommended wire size for a circuit carrying 80 amps of current is typically 4 AWG (American Wire Gauge).
15 amps.
