## Can I use 12 gauge wire for lights?

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..

## Can I mix 10 and 12 gauge wire?

You haven’t said how you will manage the transition from 10 gauge to 12 gauge. If you are thinking of wire nuts in a junction box, then the answer is that you cannot do this safely. … Your larger breaker (30A, the maximum 10 gauge is rated for) will not trip in this situation and the 12 gauge wire may start a fire.

## What happens if wire gauge is too small?

The more power and equipment you have, the larger the wire needs to be. … If too small of a size is used, the wire could melt because of the large amount of current flowing through it compared to how much the cables can handle. The smaller the wire diameter, the higher the resistance there will be to the flow of energy.

## 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 far can you run a 12 gauge wire?

The following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size (AWG) and circuit voltage….For 120-volt circuits:14 AWG50 feet12 AWG60 feet10 AWG64 feet8 AWG76 feet6 AWG94 feetOct 20, 2019

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

10 outletsGenerally, homes have eight to 10 outlets on a 15 amp breaker but not all are used at the same time. Lights and outlets are normally wired on separate branch circuits, which means that the lights will be protected by a separate circuit breaker to the one which protects the outlets.

## Is higher AWG better?

American Wire Gauge (AWG) is a U.S. standard set of non-ferrous wire conductor sizes. … The higher the gauge number, the smaller the diameter and the thinner the wire. Since thicker wire carries more current because it has less electrical resistance over a given length, thicker wire is better for longer distances.

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

NEC 240.4(D)(3) states that 14 AWG must be protected at 15A. 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.

## 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.

## Can I mix 12 gauge and 14 gauge wire on a 15 amp circuit?

It is perfectly acceptable to use 12 gauge wire on a 15 amp circuit.

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

However, 12-gauge wire is acceptable on both 15- and 20-amp circuits, so some electricians use it exclusively when wiring a house.

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

Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too. There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire.

## 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.

## What is 12 gauge wire used for?

General Purpose Cords14 – Wire12 – Wire10 – WireRecommended ForRecommended ForRecommended ForCommon residential wiring: Light fixtures, household receptacles.Common residential wiring: Light fixtures, household receptacles, small appliances.Large household appliances: Window air conditioner units, clothes dryers.4 more rows

## Can 14 gauge wire be used for outlets?

Yes you may use No. 14 AWG Cu wire for outlets but the Circuit Breaker to protect the circuit should be only 15A. Do not use 20A Circuit Breaker for this circuit. … The circuit should not have more than 10 receptacles.

## 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.

## How many LED lights can I put on a 15 amp circuit?

Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.
