Can 30 amp breaker Use 8 AWG?
Originally Answered: Can an 8-gauge wire handle 30 amps? Yes, it can. Under the NFPA Article 70 (National Electrcal Code), #8 wire is rated for 50 amps under certain conditions, however it is usually protected at 40 amps.
What size wire do I need to run 300 feet?
for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit, Jul 28, 2014.
What size wire is good for 35 amps?

What gauge wire is needed for 220?
If you’re wiring a 220v, 20-amp outlet to run power tools, you can use the same 12-gauge wire you would use for a 110-volt, 20-amp circuit. Remember that the cable must have an extra hot wire. If the appliance draws 30 amps, you need a different type of receptacle, and the cable needs to be 10-gauge.
Will 6-gauge wire fit in a 30 amp breaker?
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”Sep 18, 2017.
What size wire is needed for 240 volts?
Before You Start Also, make sure the amperage of the breaker matches the amperage of the circuit wires and the appliance being powered. A 20-amp 240-volt circuit calls for 12-gauge wire; a 30-amp circuit calls for 10-gauge wire; a 40-amp circuit calls for 8-gauge wire; and a 50-amp circuit calls for 6-gauge wire.
Can I use 14 gauge wire on a 30 amp circuit?
If the wire to the 30 Amp breaker is only 14 gauge, you don’t have a breaker, you have a 30 foot long fuse, and it will burn in two before the breaker senses the need to trip. Check out the fan and light if you match the wire size to the breaker size. Yes, it is.
