# Quick Answer: Can I Use 14 Gauge Wire On A 20 Amp Breaker?

## What happens if you put a 20 amp breaker on 14 gauge wire?

If you plug in several devices on an outlet that total 20 amps, you will exceed the safe working capacity of the 14 gauge wire without tripping the breaker.

(You may be under 15 amp for each individual outlet but between the two outlets on a duplex receptacle you can exceed the 15 amp rating of 14 gauge wire)..

## Can you put lights and outlets on the same circuit?

Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes.

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

eight lightsTypically, you can have no more than eight lights or electrical outlets on a 15-amp circuit. To determine the amp rating of a circuit, just look at the number on its breaker or fuse in your main electrical panel.

## Can I 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 14 2 wire be used for outlets?

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. … In general it’s “safe” to use a larger wire-size than required and the smallest fuse or breaker ampacity that the equipment will permit.

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

The total circuit would be about 60 -70 feet in length. It would only be supplying about 5 outlets and one light. It would be a light load, running small things, no heaters or med/large equipment. #12 provides reasonable performance up to about 100′ with general loads like you describe.

## What is the minimum gauge wire for a 20 amp circuit?

Amperage and Wire Gauge Building codes based on the National Electrical Code prohibit the use of 14-gauge wire anywhere on a 20-amp circuit. All wiring in such circuits must be 12-gauge or larger.

## How many outlets can one GFCI protect?

There’s no limit. A standard GFCI will protect up to 20 amps, drawn from any combination of receptacles, either the built-in one or any number of additional ones connected to its load terminals.

## Should I use 15 or 20 amp outlets?

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. Residential garages occasionally have 20-amp receptacles to accommodate larger power tools.

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

13 receptaclesFor 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.

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

14–2 wire is allowed for a 15 Amp circuit, and at 120 Volts, 15 Amps x 120 volts = 1800 volt-amperes. So that would allow ten (10) receptacles, you would probably derate that to eight (8) for an 80% safety factor.

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

10 receptaclesOne 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.

## Is it OK to use 12 gauge wire on a 15 amp circuit?

Because it’s thinner and lighter, 14-gauge wire is easier to run than 12-gauge wire. However, 12-gauge wire is acceptable on both 15- and 20-amp circuits, so some electricians use it exclusively when wiring a house.
