The American Wire Gauge code table shows 8 gauge safe for 24 Amps, 10 Gauge for 15 Amps. If the circuit is going to be used at capacity (2400 Watts in this case), 8 or 10 gauge is the minimum, if load is constant, use 8 gauge. Voltage ability of the wire is dependent on the insulation thickness and material. So 20 amps at 120 Volts is 2400 watts of power, and 20 amps at 12 volts is 48 watts of power. Both would require the same gauge of wire, but the higher voltage would need better insulation. <<>> This is a voltage drop question. A #1 copper conductor will limit the voltage drop to 3% or less when supplying 20 amps for 500 feet on a 120 volt system.

A #6 aluminum conductor will limit the voltage drop to 3% or less when supplying 20 amps for 200 feet on a 240 volt system.

For single phase 30 amps at 120 volts you would need a #8 copper wire with an insulation rating of 90 degrees C.

The minimum wire size allowable would be 10 gauge. For a 75 foot run however, the voltage drop would be 5.31 volts. This exceeds the NEC recommendation of no more than 3% (3.6v) so while it is not legally required, for best efficiency, you should run 8 gauge.

Heavier wires do not necessarily mean better sound. Typically, 18 or 16 guage wire is sufficient for home audio systems. If you are going to be running extremely long distances, say 100 feet or more, then increase the gauge size to like 14 or 12 to keep from losing too much audio signal. In a car, 18 guage wire should be quite sufficient.

A #14 wire will do the job.

For a 50 feet distance with 120 volts and 12 amps, you should use a 14-gauge wire to ensure electrical safety and efficiency. A 14-gauge wire is rated to handle up to 15 amps for household wiring applications.

You have to know the maximum amps you wish to deliver or draw of the device or devices you wish to power. There are charts on the internet for wire gauges and distance that you can follow. For example: A 12 gauge wire will handle 20 amps safely for runs up to 100 feet. You go down 1 gauge for runs over 100 feet. So if you are running 175 feet at 20 amps you should use 10 gauge so voltage drops don't occur. Voltage has no effect on rated current output other than selecting a wire or cable that is rated for the working voltages. 20 amps at 240 volts is the same as 20 amps at 120 volts. As long as the wire is rated at 240 volts, it will carry 20 amps at voltages less than 240 the same.

For a 25 amp load at 220 volts over a distance of 75 feet, you will need a 10-gauge wire to ensure safe and efficient electrical conductivity. This wire size allows for minimal voltage drop and meets the necessary ampacity requirements for the circuit. Make sure to consult local electrical codes and regulations before installation.

8 gauge wire can typically carry up to 40 amps at 120 volts AC over a distance of 25 feet. However, it is important to consult the specific wire manufacturer's specifications and consider other factors such as temperature, installation conditions, and local electrical codes when determining the ampacity of the wire for a particular application.

For a 15 amp circuit over a distance of 300 feet, you would typically need a 14-gauge wire to minimize voltage drop and ensure safe operation. Using a larger wire size, such as 12-gauge, would offer even better performance and safety margin.

For single phase 30 amps at 120 volts you would need a #8 copper wire with an insulation rating of 90 degrees C.

A 16 gauge wire can typically carry around 10-13 amps at 120V AC over a short distance like 25 feet. It's important to follow standard safety practices and consult with an electrician to ensure that the wire gauge is appropriate for your specific application and local electrical code requirements.

The maximum distance a 12 gauge electrical wire can run depends on the voltage and amperage of the circuit it is serving. In a typical residential circuit with 120 volts and 20 amperes, a 12 gauge wire can run up to 60 feet before voltage drop and overheating become concerns. It is always best to consult local electrical codes and standards for specific guidance on wire length limitations.
