![]() Using them for a 40 Amp circuit is inherently wrong and might result in an electric accident. 10 AWG and 12 AWG copper wires have 35 Amp and 25 Amp wire ampacity. Is 10 Gauge Wire Good For 40 amps?ġ0 AWG wires and 12 AWG wires are not suitable for 40-amp circuit breakers. You should always refer to the manufacturer information to ensure that your device requires a 40 Amp dedicated circuit. ![]() Large electric water heaters (75 gallons and above).Common models of electrical ranges and ovens.Some of the common applications of 40-Amp dedicated circuits include: A 40-amp breaker is capable of handling up to 4800 watts. What can a 40-Amp Circuit Handle?Ī 40-Amp circuit, in most cases, is a dedicated circuit set aside for a specific device. This means using 6-gauge copper wire or 4-gauge aluminum wire for cables running over 100 feet and using 4-gauge copper wire or 2-gauge aluminum wire for cables running over 200 feet. If your wire for a 40 AMP breaker runs for a long distance, you should accommodate a voltage drop when choosing a 40 Amp breaker wire size. This is based on the allowable ampacity of these particular cable sizes: the ampacity of the 8 AWG copper wire is 50 amps at 75☌, and the ampacity of the 6 AWG aluminum wire is 50 amps at 75☌.Ħ AWG copper wire with an ampacity of 65 amps at 75☌ and 4 AWG aluminum wire will also be excellent choices if you are dealing with higher loads or want to be safe from an overload. The minimal wire gauges for a 40 Amp circuit breaker are 8 AWG copper or 6 AWG aluminum.
