For the short distance of 50 feet no voltage drop calculations are needed.
A #10 copper conductor with a insulation factor of 60, 75 or 90 degrees C is rated at 30 amps respectively. This conductor can legally be loaded to 80% capacity. This allows 30 x .8 = 24 amps. If the device draws more that 24 amps then go to the next wire size which is a #8. A #8 copper conductor with an insulation factor of 75 and 90 degrees C is rated at 45 amps respectively. This legally allows 45 x .8 = 36 amps to flow on the wire. Of course with this size wire only 30 amps will be allow to flow before the breaker will trip.

∙ 12y agoFor a 50' run with 30 amps at 240 volts, you should use 10 AWG copper wire. This gauge wire is rated for 30 amps and will ensure safe and efficient power delivery for your circuit.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
the wire size should be appropriate for the maximum current the device will draw to prevent overheating or voltage drop. It is important to follow electrical code and safety guidelines when selecting a wire size for a line cord. Consider factors such as voltage, current, and length of the cord when choosing the appropriate wire size.

The conductor for H2 connection on a 480 volt wire transformer should be marked:
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.
Use 8 gauge wire.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
The wire size is large enough to carry the load current and that the cord is properly voltage rated.

As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
The wire size depends on how much current it will conduct.

The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
AWG # 10 wire on 30 amp circuit.
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
Depends on the size of the circuit which you did not list.
