What Size Wire For 40 Amp Double Pole Breaker at Mary Turpin blog

What Size Wire For 40 Amp Double Pole Breaker. The minimal wire gauges for a 40 amp circuit breaker are 8 awg copper or 6 awg aluminum. To determine the breaker and wire size you need, divide the total watts by the voltage to find the amperage on the circuit. However, some professional electricians prefer to use a 6 gauge wire, and there is nothing wrong with it. If you look at a 40 amp wire size chart, you can see that the recommended wire size is a minimum of 8 gauge. It’s useful to know that you need the same wire for any voltage: Keep in mind that the. 40 amp 240 volt circuit requires the same size wire as 40 amp 220 volt circuit or even 40 amp 110/120 volt. The ampacity of the 8 awg copper wire is 50 amps at 75°c, and the ampacity of the 6 awg aluminum wire is 50 amps at 75°c. This is based on the allowable ampacity of these particular cable sizes: Choosing the correct wire size for a 40 amp breaker is essential, as too small a wire size can cause overloads and other related issues.
