This gauge is thicker than the 12 gauge wire size, and it will be hard to wire up a 15 amp outlet. Is It Suitable to Use 10 Gauge Wire on 15 Amp Breaker?įor a 240V 15 Amp wire size, 10 gauge wire is suitable. 14 Gauge is suited for current overloading under a 15 amp circuit.

However, the 15 amp wire size of gauge 12 is not fit when current overloading occurs. It may serve a lot of outlets and lighting wirings.ġ2 gauge wire is the most commonly used wire size in all construction because of its flexibility and versatility. How Far Can You Run 12 Gauge Wire on a 15 Amp Circuit?ġ5 amp breaker wire size of 12 gauge can run as far as 70 feet. It is relatively safe to choose the thicker wire for higher amperage of electricity without overheating since it allows delivery of power in long wire with less risk of voltage drop.īesides, 12 and 14 gauges are considered suitable as a 15 amp wire gauge for a 15 amp circuit breaker. Therefore, 12 gauge wire is thicker than 14 gauge wire, thus offering versatile uses. Generally, there is not much difference between the two but the thickness of the wire.īy dimension, 14 gauge wire has a diameter of 1.628 mm while 12 gauge wire has 2.053 mm. What Gauge Wire for 15 Amp Circuit? Is It 14 Gauge Wire or 12 Gauge Wire? What Is Their Difference?

Therefore, choosing the exact wire size impacts the function of the circuit breaker for a steady flow of controlling electricity. Gauge 18 is for low-voltage lighting and cords.Gauge 16 is for light-duty extension cords.Gauge 14 is for circuits, devices, and lighting fixtures.Gauge 12 is for small AC units and residential outlets.Gauge 10 is for water heaters, large AC units, and dryers.Gauge 6 is for kitchen cooktops and ranges.

Gauge 4 is for furnaces and large heaters.
