# FAQ: How far can you run 12 2 wire?

## How far can you run 12 2 wire on a 20 amp breaker?

Originally Answered: How far can you run 12 gauge wire on a 20 amp circuit? You don’t want the voltage drop to exceed 3%, or 3.6 V. A length of 53 feet will cause a voltage drop of 3.6 V. So I would say 50 feet is the max length on a 120 V, 20 A permanent branch circuit.

## How many feet can 12 gauge wire run?

As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 percent voltage drop. For 240-volt circuits:

14 AWG 100 feet
12 AWG 120 feet
10 AWG 128 feet
8 AWG 152 feet
6 AWG 188 feet

## Will a 12 2 wire carry 30 amps?

No. 12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps. Electrical current is measured in amperage ( amps ), and each wire gauge has a maximum safe carrying capacity.

## How far can you run 10 2 wire?

The size of the wire you run to your shed depends on how far away it is and whether you use 120V or 240V. If your shed is 50 feet from your breaker box, you can use 10/2 AWG UF-B wire for a 120V circuit up to 20A.

## Should I use 12 or 14-gauge wire?

If you’re wiring a circuit on which there are both lights and outlets, or you just aren’t sure which wire gauge to use, you can’t go wrong by choosing a 12 – gauge wire. It’s not quite as flexible as a 14 – gauge wire, and it costs a bit more, but it’s always a safe choice on a 15- or 20-amp circuit.

## Is it OK to mix 12 and 14-gauge wire?

The amp capacity for 12 – gauge wires is 20 amps, and while you can technically use 14 – gauge wires on 20-amp circuits, it is not recommended.

## How many outlets can you put on a 14 2 wire?

for both 15A and 20A circuits the rule of thumb is a maximum of 10 receptacles per circuit. 15 amp breaker circuit 14/2 wire. Some say to limited total number of outlets to 10, meaning the total number of consistent in-use outlets, correct?

## How many outlets can I put on a 20 amp breaker?

One rule of thumb is to assign a maximum draw of 1.5 amps to each receptacle, which allows for 10 receptacles on a 20 – amp circuit.

## How many outlets can be on a 15 amp breaker?

Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.

## Can you use 12 2 wire for 220?

If you ‘re wiring a 220v, 20-amp outlet to run power tools, you can use the same 12-gauge wire you would use for a 110-volt, 20-amp circuit. If the appliance draws 30 amps, you need a different type of receptacle, and the cable needs to be 10-gauge.

## How many amps can a 10 gauge wire handle at 12 volts?

Example – 12 V Cable and Maximum Length and Current The maximum current in a gauge #10 ( 5.26 mm2) cable with length 15 m is approximately 5 amps.

## Can you use 14 gauge wire on a 20 amp breaker?

You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. Just use the side terminals.

## Can you use 10 2 wire outlet?

Yes, you can use 10 AWG copper conductors with a 20 ampere breaker. The smallest size conductors you could use with a 20 ampere breaker, are 12 AWG copper conductors.

## How long can you run 14 2 wire?

It’s 40 feet(80 feet) just to the first receptacle, then all the extra length in between 8 receptacles. I think 8 receptacles on 14/2 is fine for an attic bedroom if voltage drop won’t be an issue.

## How long can you run electrical wire?

In fact, the run of 10 miles will generally be less of a hazard, since the resistance of the wire will reduce the current. As a rough rule of thumb, try to keep the wiring of your 120-volt general purpose circuits under 75 feet in length. When you go over than, consider upping the wire size by one.
