12-gauge.
Why Wire Gauge Is Important
| Wire Use | Rated Ampacity | Wire Gauge |
|---|---|---|
| Low-voltage lighting and lamp cords | 10 amps | 18-gauge |
| Extension cords (light-duty) | 13 amps | 16-gauge |
| Light fixtures, lamps, lighting circuits | 15 amps | 14-gauge |
| Kitchen, bathroom, and outdoor receptacles (outlets); 120-volt air conditioners | 20 amps | 12-gauge |
Can you use 14 gauge wire on a 20 amp circuit?
14 AWG must be protected at 15A, according to NEC 240.4(D)(3). 14 AWG can’t be used on a circuit with a 20A breaker. The screw terminals are the better choice if you want to put 15 Amp receptacle on a 20 Amp circuit with 12 gauge wire. You can use the side terminals.
How far can you run 12 gauge wire on a 20 amp circuit?
Originally Answered: How far can you run 12 gauge wire on a 20 amp circuit? About 400 feet. After that voltage drop is a factor and the gauge will have to be increased or the voltage increased.
Can I mix 12 and 14 gauge wire on a 20 amp circuit?
Generally speaking, #12 is good for 20A and #14 is only good for 15A. So if you have a 15A circuit, you could mix them with no problem. However if you have a 20A circuit, you can’t use #14 at all.
How far can you run 10 gauge wire on a 20 amp circuit?
How Far Can You Run 10 Gauge Wire? You can run a 10 gauge wire up to 85 feet on a 20 amp circuit. If you opt to use this type of wire on a 15 amp circuit, it can run up to 115 feet. After these distances, the circuit will go over the recommended 3% voltage drop.
Should I use 12 or 14 gauge wire?
As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire.On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.
What happens if you put a 20 amp outlet on a 15-amp circuit?
If your question is can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?, the answer is yes, because the receptacle can handle more current than the circuit is rated for. If you exceed 15 amps, the breaker will blow, and protect the receptacle.
What cable do I need to run power to my shed?
You should always hire an experienced and qualified electrician to make sure the job is done safely and properly. They will install an SWA cable (otherwise known as a steel wire armoured cable) from your property to your shed. This is designed to be safe to bury in the ground, as it is impervious to water and rotting.
What is 10 2 Romex used for?
The following NEC regulations apply to Romex conductors:
| Wire Gauge or Type | Rated Amperage | Common Uses |
|---|---|---|
| 10-2 Romex | 30 A | Electric water heater, baseboard heaters |
| 10-3 Romex | 30 A | Electric Clothes Dryer |
| 6/3 Cu Range Cable | 50 A | Range, Heatpump, On-Demand Electric Water heater |
| 2 Gauge Copper | 100 A | Central Electric Heat |
Can you run lights and outlets on the same circuit?
Yes, you can. The average home uses an indoor distribution board that houses the breakers of the majority of circuits in the home. A circuit controlled by a 15A circuit breaker (which a lot of contractors use for general lighting) can also accommodate outlets.
Does a refrigerator need to be on a dedicated circuit?
Having the refrigerator on its own dedicated circuit is the recommended best practice for homeowners.You should have refrigerators and freezers installed on a 15-20 amp dedicated 120 volt circuit. This will avoid an electrical overload due to your current wiring not being capable of handling the additional power.
Is higher gauge wire better?
In general, a lower AWG number is better than higher AWG.Since these electrical signals are usually low power, smaller AWG (larger wire) is not needed. In these situations, proper shielding and cable-pair twisting is more important for signal integrity than the AWG of the strands.
Is it OK to use 12-gauge wire on a 15 amp circuit?
Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.
What size wire do I need to run 400 feet?
| Aluminum SEC Wire Size for Long Runs for 200A Service | ||
|---|---|---|
| Cable Size1 | Distance Ft. / M | Phase |
| 250 kcmil | 200 / 60 | 3 |
| 400 kcmil | 250 / 75 | 1 |
| 350 kcmil | 250 / 75 | 3 |
Can you mix 12 and 10 gauge wire?
It would be fine (if you follow all the rules for sub-panels) to run 10 gauge wire protected by a 30A breaker to a sub-panel and then run 12 gauge wires each protected by a 20A breaker from the sub-panel.
What size wire do I need to run 300 feet?
for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit,
What is 20amp wire?
Why Wire Gauge Is Important
| Wire Use | Rated Ampacity | Wire Gauge |
|---|---|---|
| Low-voltage lighting and lamp cords | 10 amps | 18-gauge |
| Extension cords (light-duty) | 13 amps | 16-gauge |
| Light fixtures, lamps, lighting circuits | 15 amps | 14-gauge |

What gauge wire is used in houses?
Wire Gauge
The most common sizes you’ll find in residential work are 14-gauge and 12-gauge. Larger appliances such as electric stoves, electric water heaters, electric dryers and central air units will often use 10-, 8- or even 6-gauge wire.
Can I plug anything into a 20 amp outlet?
You can use a device that has a 15-amp plug with either a 15- or 20-amp receptacle. Standard 15-amp receptacles are suitable for typical household appliances, lamps and other accessories. A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors.
Is it OK to replace a 15 amp breaker with a 20 amp?
The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
Do I need 20 amp outlets in kitchen?
Kitchens must have at least two 20-amp outlets. These outlets are used to power high voltage appliances such as toasters, blenders, and microwave ovens.The necessary power supply to operate common kitchenware appliances typically is 20 Amps.
