Wire Gauge For 40 Amp Breaker. if you look at a 40 amp wire size chart, you can see that the recommended wire size is a minimum of 8 gauge. When purchasing wire, you'll see a few different numbers on the packaging or product description. Therefore you will need to run an 8 awg wire for it. However, there are a few factors that may influence the size of wire you need to use. Look at the wire sizes with an ampacity around and above 40 amps. apply the 80% nec requirement for your amperage. Namely, we will calculate the minimum ampacity a wire has to have (how many amps they can handle) to be adequately sized for a 40 amp circuit. for a 40 amp breaker, the recommended wire size is 8 gauge for copper wire. Check the wire awg chart here. You can consult the wire ampacity chart from the 1st chapter and see that the most appropriate wire size for 40 amps is 8 awg wire. you can determine the ampacity of wires you have on hand, and the gauge—or diameter—of wires needed for your project with a wire gauge chart. 40 amp wire size.
