6-gauge wire
“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
Beside this, Can 10 gauge wire handle 40 amps?

Likewise, What gauge wire should I use for 240 volts?
Wire Use Rated Ampacity Wire Gauge
——————————————————————————— ————– ———-
Electric clothes dryers, 240-volt window air conditioners, electric water heaters 30 amps 10-gauge
Cooktops and ranges 40-50 amps 6-gauge
Electric furnaces, large electric heaters 60 amps 4-gauge
Also, Can I use 10 gauge wire on a 50 amp breaker?
A 10 gauge wire can handle 50 amps bare copper like a power line but most insulated wire is rated by NEC at 35 amps max with a 30 amp circuit the normal use for 10 gauge. 50 Amps is a large current and it will make 10 guage wire to heat up.
What is the max amps for 10 gauge wire?

What gauge wire is needed for 240v?
Each appliance needs a separate double-pole breaker. Some older receptacles use only three wires; codes now call for four wires—black and red hot wires, a white neutral wire, and a ground wire. Use 12-gauge wire for a 20-amp circuit, 10-gauge for 30 amps, 8-gauge for 40 amps, and 6-gauge for 50 amps.
What gauge wire is needed for 220v?
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.
What wire do I use for 220v?

What size breaker do you need for 240 volts?
Welder Circuits For example, 240-volt, 40- to 50-input amp welders will require a 50-amp circuit breaker and 6-gauge wiring. Welders operating at 30 to 40 input amps require a 40-amp breaker and 8-gauge wire. Small welders operating below 30 input amps can use 10-gauge wire with a 30-amp circuit breaker.
What amperage can 10 gauge wire handle?

Can I use 8 gauge wire for a 50 amp breaker?
8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable.
What amp breaker do you use for 8 gauge wire?
Many techs will repeat these rules of thumb and rely on them in all circumstances: “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 kind of Breaker do I need for 240 volts?
Double-pole breakers: Provide 240 volts, 20-60 amps and have two hot wires that share one neutral wire.
Can 10 gauge wire handle 60 amps?
Not only is #10 wire on a 60 amp breaker a bad idea, it is completely against code. Also, the 60 amp breaker is completely unnecessary. A 30 amp breaker (which IS correct for #10 wire) is adequate for this compressor.
What size wire do I need for 60 amps?
4-gauge wire
Can 8 gauge wire handle 50 amps?
8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable.
What size breaker do I need for 240 volts?
120 Volt heaters require 1-Pole circuit breakers; 240 Volt heaters need 2-Pole breakers.
