Can I use 10 gauge wire on a 20 amp circuit?
Yes, you can use 10 AWG copper conductors with a 20 ampere breaker.
The smallest size conductors you could use with a 20 ampere breaker, are 12 AWG copper conductors.
There’s no problem using larger conductors, other than cost to you, and difficulties associated with working with thicker conductors..
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.
Should I use 12 or 14 gauge wire?
As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. … On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.
Is it OK to mix 12 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 far can you run 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
Can you run 12 gauge wire on a 30 amp breaker?
No. 12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps.

Can you use 10 2 wire outlet?
Safety wise, it is fine to use a larger than required wire. Mechanical wise, a #10 should fit in the breaker OK (look at specs on breaker), but might not in the GFCI.
What is the minimum gauge wire for a 20 amp circuit?
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.
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 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 outlets can you put on a 15 amp breaker?
I’m ask so many times how many outlets and or lights can I put on a 15 amp or 20 amp breaker. Well NEC code does not have it listed that way. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker. Now this is of course they are 120 volts 60 Hz (USA or Canada).
What is 14 gauge wire used for?

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.
What happens if wire gauge is too big?
using larger wire will not hurt anything or cause any overload. The larger wire will cost more, the pathway or where it has to fit, and the physical size of the connecting means (ie. the size of terminal or clamp it has to fit in), will all be determining factors in just how big is too big.
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.
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.
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.
