Consequently, what gauge wire should I use for lights?
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.
Beside above, can I use 14 gauge wire for outlets? So yes, you can use 14 AWG wire for a 15A receptacle, but only if it's on a 15A branch circuit. In the US, electrical code allows 15A receptacles to be used on a 20A branch circuit, so just because you are wiring 15A receptacles doesn't mean it is OK to use 14 AWG wire.
Consequently, 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 use 16 gauge wire for lighting?
The 18-gauge wire inside a lamp cord is rated for a maximum current draw of about 5 amps. If the same bulb runs on 12-volt power, however, you should upgrade the cord to 16- or even 14-gauge to avoid voltage drops and dim lights.
How do I know what gauge wire to use?
Wire gauge refers the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter. Common sizes include 14-, 12-, 10-, 8-, 6-, and 2-gauge wire.Can you mix 12 gauge and 14 gauge wire?
mixing 14-gauge NM and 12-gauge. both 14 and 12 gauge will be protected by a 15A breaker. Code states that 14Ga will be protected by an overcurrent device of not more than 15A and 12GA by 20A. 14 and 12 are both ok behind a 15amp breaker, but you must use one or the other and not both.What is 14 gauge wire used for?
14-gauge wire is the smallest allowed for the permanent wiring of a circuit. 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.Which is better 12 gauge or 14 gauge?
The diameter of solid 12 AWG wire is approximately 0.0808 inches (2.053 mm), and 14 AWG is 0.0641 inches (1.628 mm). Therefore, 12 AWG wire is about 26% thicker and has 59% more cross-sectional area than 14 AWG wire. For example, in the gauge system used for steel music wire, a bigger number means a bigger wire!What is 10 gauge wire used for?
building wire| 14 - Wire | 12 - Wire | 10 - Wire |

| Common residential wiring: Light fixtures, household receptacles. | Common residential wiring: Light fixtures, household receptacles, small appliances. | Large household appliances: Window air conditioner units, clothes dryers. |
What wire do I use for a switch?
Two or three wires will be attached to the switch: an incoming hot wire, which is black; a return wire, which carries the load to the fixture and may be black, red, or any other color except green; and sometimes a grounding wire, which is green or bare copper.What is the standard gauge for household electrical wire?
Wire Gauge The most common sizes you'll find in residential work are 14-gauge and 12-gauge. Larger appliances such as electric stoves, electric water heaters, electric dryers and central air units will often use 10-, 8- or even 6-gauge wire.Can you connect 10 gauge wire 12 gauge?
A 12 gauge wire needs a 20A breaker to protect it. It would be fine (if you follow all the rules for sub-panels) to run 10 gauge wire protected by a 30A breaker to a sub-panel and then run 12 gauge wires each protected by a 20A breaker from the sub-panel.How many watts will 12 gauge wire carry?
