# Quick Answer: How far can you run electrical wire?

Contents
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 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 far can you run 12 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. You can run a 12 gauge wire up to 70 feet on a 15 amp circuit.

## 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.

## Will 1 0 aluminum wire fit in a 100 amp breaker?

No, Al #1/0 is good for a maximum of 125A in a dwelling service; possibly 100A if the distance is longer than 100′ or so. A 200A service requires a minimum of #4/0 aluminum or #2/0 copper; upsized accordingly if there is a long distance involved.

## How far can I run 220v wire?

1 conductors per phase utilizing a #8 Copper conductor will limit the voltage drop to 4.35% or less when supplying 20.0 amps for 400 feet on a 220 volt system.

## 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.

## Is it OK to oversize wire?

yes, as long as it fits under the breaker lugs it is fine. Many times wire is oversized due to long distance pulls resulting in increased voltage drop. The thing you cannot do is undersize the wire for the rated breaker it is under.

## 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.

## How deep do you have to bury electrical wire?

In general, bury metal conduits at least 6 inches below the soil surface. You may also run them at a depth of 4 inches under a 4-inch concrete slab. Under your driveway, the conduits must be below a depth of 18 inches, and under a public road or alleyway, they must be buried below 24 inches.

## How far can you run 12 gauge wire on a 15 amp circuit?

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