What wire size should you use for with a 50 amp breaker?

Answer 1

Breakers and wires can not be connected together this way. It is the amperage of the load that govern the wire size.The breaker is then chosen to protect the wire size amperage. It also depends on what the load is. If it is a motor, then the breaker is 250% of the motors full load amperage, even though the wire size remains the correct size to carry the motors full load amperage. A #6 copper conductor with an insulation rating of 90 degrees is rated at 60 amps.

Answer 2

Depends upon how many volts, for one thing, and how far it needs to go, and whether it is copper wire or something else, and what kind of load.

In theory, you could run a continuous load of 50 amps at 240 volts at up to 47 feet away, using 10AWG conductors and only lose 3 percent of your 62.5 amp design goal. For 120 volts you would need at least 6AWG, but it would get you up to 60 feet with only a 3 percent voltage drop.

Note that you cannot run a 50A load 100 percent of the time on a 50A over-current protection device, so you would need a 65A breaker for a constant 50A load.

Answer 3

Check your local electric codes first, but a #6 guage wire should be appropriate.

Answer 4

#8 with a #10 ground. A #8 copper wire with insulation rated at 90 degree C is only rated at 45 amps. A #6 copper wire with insulation rated at 90 degree C is rated at 65 amps.

Answer 5

# 8 awg (american wire gauge) wire minimum, although #6 is preferred.

Answer 6

For the USA, Canada and countries using 60 Hz supply, you need a AWG #6 copper conductor.
