Mell Can you use 10-gauge wire 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].”
Can you use 10 2 wire AC?
10/2 is acceptable for a single-appliance circuit where the appliance needs ONLY 220v. Central air compressors would usually fall in this category. You’d need 3 wire cable (with a neutral) for appliances where an appliance may require dual voltages.
What wire do I use for a 30 amp outlet?
What gauge wire for 30 amp breaker. The best wire to use for a 30 amp breaker is a 10-gauge wire.
