It’s 12/3 + ground. Yes, this is allowed. If your needs warrant it, you might consider a multi-wire circuit, which will give you twice the available power. At the very least, do not cut the extra wire short, just push it o the back of the boxes out of the way, so it can be used if needed.

12-3 cable is four wire cable, all 12 gauge. One conductor is black, one is white, one is red. and one is bare (no insulation). Except for a switch loop, the black and red are used for hot wires and the white is used for the neutral.
Thereof, What is a 12 3 wire for?
A 12-3 Romex will have a black(hot), red(hot), white(neutral), and bare copper. The red on a 12-3 is used for three-way light switches which are covered later. 12 gauge Romex is rated for 20 Amps and is commonly yellow jacketed.
Also to know is, Can I use 14 3 wire for outlets? 14–3 contains 4 wires: one ground, one neutral and two hot wires (one black and one red). Fred is correct that a 14–3 wire should be used for what is called a three way switch, but it can be used in several other places as well. They can share a common neutral and ground wire.
Subsequently, question is, What is the difference between 12 2 wire and 14 2 wire? 12-Gauge Vs 14-Gauge Wire A standard 12-gauge copper wire has a diameter of 2.05 mm, while the diameter of 14-gauge copper wire is only 1.63 mm. 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.
Also, How many amps can 14 3 wire handle?
It is rated as able to carry up to 15 amps of current. 12-gauge wire is the next size larger and is allowed to carry up to 20 amps.
How do you wire an outlet with 12 3 wire?
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.
Where can you use 12/3 wire?
AWG 12/3 is used for double breaker 240V 20A max circuits. With 12/2, the black wire goes to the breaker and the white wire to the ACN bus. The load at the other end of the wiring connects between the black and white wires, and uses 120V to operate.
Why does my electrical outlet have 3 wires?
Three-conductor wire has two hots — black and red — and a white neutral. Though normally used for three-way switching, three-conductor wire is commonly used for duplex receptacle wiring as well. … The black or the red can go to a permanently hot feed, while the other goes to a wall switch, creating a switched outlet.
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.
Can 14 AWG handle 20 amps?
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 many amps can 12 3 wire carry?
20 amps
Can I use 12 gauge wire for outlets?
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.
What is a 14 3 wire used for?
Short answer, you use a 14-3 cable to wire a home light that is controlled by two different switches. Slightly longer answer. The 14 refers to the gauge, or thickness of the wire. The lower the number the thicker the wire and the more current it can carry.
