Wire gauge amp chart 120v

Household wiring for 120-V circuits is almost always 12- or 14-gauge copper wire, depending on the current load and length of the circuit. The diameter of the metal conductor in a 12-gauge copper wire is 0.0808 inches; of a 14-gauge wire is 0.0641 inches.

What size wire do I need for 120 amps?

Wire Size		75°C (167°F)
2	(33.6)	90
1	(42.4)	100
1/0	(53.5)	120
2/0	(67.4)	135

What gauge wire do I need for 110 volts?

Wire Use	Rated Ampacity	Wire Gauge
Low-voltage Lighting and Lamp Cords	10 Amps	18 Gauge
Extension Cords	13 Amps	16 Gauge
Light Fixtures, Lamps, Lighting Runs	15 Amps	14 Gauge
Receptacles, 110-volt Air Conditioners, Sump Pumps, Kitchen Appliances	20 Amps	12 Gauge

What size wire is needed for a 20 amp 120 volt circuit?

The perfect wire gauge of a 20 amp breaker is the #12 AWG wire.

How far can you run 10 gauge wire for 120v?

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.

Is 120-volt the same as 20 amp?

While 120-volt outlets generally run on 15 amps, higher power rated ones are 20 amps. An example is a 125-volt outlet intended for larger kitchen gadgets or some types of home appliances such as dishwashers, washing machines, or space heaters.

Can you have a 30 amp 120-volt circuit?

These receptacles are not GFCI protected. A 30 amp 120-volt receptacle can be used in a dual-circuit system. When two receptacles are connected to the same circuit, they will supply 120 volts at twice the current. However, receptacles on the same circuit will trip the breaker when they exceed their rated current.

How many amps can a 120V outlet handle?

If, like most homes, you have a 120-volt system, you would divide 1,500 by 120 and end up with 12.5 amps being used.

How many amps can 120 volts handle?

For example, think of a simple hairdryer rated at 1,500 watts running on a 120-volt bathroom branch circuit. Using the W ÷ V = A variation of Ohm's law, you can calculate that 1,500 watts ÷ 120 volts = 12.5 amps. Your hair dryer running a maximum heat can draw 12.5 amps of power.

How many amps can you get from 110 volts?

There are a few variations of the 110 volt outlet based on the size of the breaker associated with the circuit, which is measured in Amps. The 2 most common variations are 15 Amp and 20 Amp.

What size wire do you use for a 110 outlet?

12-gauge wire is the minimum requirement for outlets on a 20-amp circuit. 12-gauge wire can be used for outlets on both 15 and 20-amp circuits.

Can you run 120v through 18 gauge wire?

18 gauge wire is safe to use at low currents. It would be recommended to fuse it though. BUT, doorbell wire is not a safe option at 120 volts. Most likely it is not intended for use above 48 volts.

Can you put 14 gauge wire on a 20 amp breaker?

You cannot use any 14 gauge wire on a 20 amp circuit. This is true, even running to a light fixture that has smaller wires built in. The wires built into the fixture are allowed as part of a manufactured assembly. However, any added wire must be appropriate to the circuit breaker protecting the wire.

Can I mix 12 and 14 gauge wire on a 20 amp circuit?

You can, but it is not a good idea. Highly discouraged. An electrical inspector may have a bird and not want to pass your installation, You will confuse anyone working on the circuit in the future as to if it is a 15 or 20 ampere circuit.

How far will 12-gauge wire carry 20 amps?

12 AWG wire. This wire will safely carry 20 amps up to 100 feet. If you plan on going over 100 feet, or if you want to run the wire in conduit, you should upgrade to 10 gauge copper wire.

How many amps can 10 gauge wire handle at 120 volts?

“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

Will #10 wire carry 40 amps?

10 Gauge Wire Amps Default 10 gauge wire Ampacity (the wire's ability to carry current) is 30 Amps @60°C/140°F, 35 Amps @75°C/167°F, or 40 Amps @90°C/194°F.

How Far Will #10 wire carry 30 amps?

Ten-gauge wire can run for up to 128 feet under 30 amps. For typical household applications, a wire of this size can handle up to 30 amps, but it's best to keep this figure in mind before you start your wiring project.

What happens if you put a 15 amp outlet on a 20 amp circuit?

Can You Put A 15 Amp Outlet On A 20 Amp Circuit? Yes. You can very well put a 15 amp receptible on a 20 amp circuit. In fact, with the highest allowable amps on a 20 amp circuit in mind, you can put a 16 amp outlet on a 20 amp circuit.

Is it OK to use 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.
