How many amps can a 8 gauge wire handle?
40 amps
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].”

How do you calculate the ampere of an 8 AWG wire?
If using 8 AWG non-metallic wires, for example, make sure that the sum of the amperes of all the electrical devices does not exceed 40 A. To compute the total amperes, add the wattage of the electrical devices and divide the sum by the voltage of the system, 110 or 120 volts.
What is the maximum current a 12 gauge wire can handle?
In accordance with US electrical codes the max current for circuits utilizing 12 gauge wire is 20 Amps. However, 12 gauge copper wire is capable of handling much higher currents. There is something called fusing current, the current at which a wire will melt. For 12 gauge copper it is about 235 Amps.
