# How far can 12 gauge wire run?

Contents

A 12 gauge wire is typically good for 15 amp at 100 feet.

## How far can you run 12 gauge wire on a 20 amp circuit?

After these distances, the circuit will go over the recommended 3% voltage drop. You can run a 12 gauge wire up to 70 feet on a 15 amp circuit. That number drops to 50 feet if you run 12 gauge wire on a 20 amp 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

## What size wire do I need for a 200 foot run?

Copper SEC Wire Size for Long Runs for 200A Service
Cable Size1 Distance Ft. / M Phase
3/0 AWG 200 / 60 3
4/0 AWG 250 / 75 1
4/0 AWG 250 / 75 3

## How many outlets can you run on a 12 2 wire?

For general use receptacles, In commercial buildings it is limited to 180VA per duplex or single receptacle, therefore on a 12/2 Romex cable not otherwise subject to ampacity derating and protected by a 20 amp circuit breaker, that would allow a maximum of 13 receptacles.

## 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.

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

How many outlets can be put on a 20 amp circuit safely? A rule of thumb is to factor a maximum draw of 1.5 amps to each receptacle, which means you can put 10 outlets on a 20-amp circuit.

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

Yes you can mix 12 and 14 gauge wire with a 15 amp breaker on the circuit. But it is not recommended because the next homeowner or electrician may be confused and put a 20 amp breaker on it again.

## Can I mix 12 gauge and 14 gauge wire?

mixing 14-gauge NM and 12-gauge. both 14 and 12 gauge will be protected by a 15A breaker. Code states that 14Ga will be protected by an overcurrent device of not more than 15A and 12GA by 20A. 14 and 12 are both ok behind a 15amp breaker, but you must use one or the other and not both.

## Can you use 10 gauge wire 20 amp breaker?

2 Answers. 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. There’s no problem using larger conductors, other than cost to you, and difficulties associated with working with thicker conductors.

## What wire size do I need to go 100 feet for a 60 amp service to a workshop?

For 60 amps #6 wire is the right size. Use RHW or THHN type insulation.

## How far can you run 14 gauge wire on a 20 amp circuit?

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.

## What size wire do I need to run 300 feet?

At 300 feet I would suggest going with the aluminum. The #2 should work just fine. With a full load of 60 amps, the voltage drop is the same as the #4 copper Ray quoted.

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

each outlet( receptacle, light) is roughly one amp so you can use 14-2 wire to 12 outlets protected by a 15 amp breaker.

## Can I use 12 2 wire for a light?

Yes, it is okay to use 12-2 cable to supply lighting fixtures. The other answer indicates that it even with 12-2 you have to use a 15A breaker for lighting circuits which is not strictly correct. If the entire circuit is 12AWG (other than fixture wires), then a 20A breaker may be used.

## How many outlets can I put 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.
