20 amps
14-2 can only be used for 15A circuits. 12-2 can be used for 15A circuits or 20A circuits. If you are in the US, you can use 12-2, a 20A breaker, and 15A receptacles (as long as you have more than 1 receptacle on the circuit). Its fine for 15 or 20 Amps.
Thereof, Can I mix 12 and 14 gauge wire on a 15 amp circuit?
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.
Also to know is, Can you 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.
Subsequently, question is, Can I 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.
Also, How many amps can a 14 2 wire handle?
20 amps
Can you use 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. … Just use the side terminals.
Can I use 12 gauge wire for lights?
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.
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.

What gauge wire do I need for LED lights?
For single color strips, you only need 2 conductor wire, and for RGB strips, you need 4 conductor wire. We recommend using stranded copper wire 10-22 gauge.

What size cable do I need for 12v LED lights?
For single color strips, you only need 2 conductor wire, and for RGB strips, you need 4 conductor wire. We recommend using stranded copper wire 10-22 gauge. You said that the lights are dimmable.
What gauge wire do I need for a 20 amp circuit?
12-gauge
Can I use 18 gauge wire for LED lights?
Now, I personally use a solid core 18 gauge wire for all my lights and would recommend you do the same. The cost difference between it and smaller cable is essentially negligible, and 18 gauge is about as big as you can go if you still want to be able to fit it into most COB holders or terminals.
Can you use thermostat wire for LED lights?
With LED lighting I just use thermostat wire. Never had a problem.
Can I use 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. … Just use the side terminals.
Is it OK to mix wire gauges?
Mixing Wire Gauges To prevent overloading, use the same gauge wire throughout a circuit. And take care to use the right size wire for the amount of amps in the circuit. Don’t go on the look of a wire. Know the amp capacity for each gauge of wire.
