When it comes to electrical wiring, there are different gauges of wire to choose from. For outlets, the two most commonly used gauges are 12 and 14. In this article, we will discuss the differences between the two and which one is better suited for certain applications.
What is Gauge?
Gauge measures the thickness or diameter of a wire. The larger the number, the thinner the wire. When it comes to electrical wiring, a thicker wire can carry more current, making it safer to use.
12 Gauge Wire for Outlets
12 gauge wire is thicker than 14 gauge wire and is capable of carrying up to 20 amps of current. It is commonly used for household outlets that require more power, such as those used for appliances like refrigerators, air conditioners, and ovens.
Using 12 gauge wire ensures that the wiring can handle the load of these higher-powered appliances, reducing the risk of electrical fires and other hazards. It is typically used for circuits with a maximum length of 80 feet.
When selecting 12 gauge wire for outlets, it is important to ensure that other components of the electrical system, such as the circuit breaker and receptacle, are also rated to handle the same amount of current.
14 Gauge Wire for Outlets
14 gauge wire is thinner than 12 gauge wire and is capable of carrying up to 15 amps of current. It is commonly used for lighting circuits and for power outlets that will be used for low-power devices such as TVs, computers, and other electronic devices.
Using 14 gauge wire for outlets that will be used for low-power devices is not only safe but also cost-effective. It is typically used for circuits with a maximum length of 50 feet.
When selecting 14 gauge wire for outlets, it is important to ensure that other components of the electrical system, such as the circuit breaker and receptacle, are also rated to handle the same amount of current.
Which is Better: 12 Gauge or 14 Gauge Wire?
The answer to this question depends on the specific application. If you are wiring an outlet for a high-powered appliance such as a refrigerator, air conditioner or oven, then 12 gauge wire is the best choice.
If you are wiring an outlet for low-power devices such as TVs, computers, and other electronic devices, then 14 gauge wire is the best choice.
It is important to note that using a wire gauge that is too thin for a specific application can cause the wire to overheat and possibly start a fire. Using a wire gauge that is too thick can be expensive and unnecessary.
Conclusion
In conclusion, 12 and 14 gauge wire are the most commonly used gauges for electrical wiring in homes. 12 gauge wire is thicker and can carry up to 20 amps, making it ideal for high-powered appliances. 14 gauge wire is thinner and can carry up to 15 amps, making it ideal for low-power devices.
When selecting a gauge of wire for an outlet, it is important to choose the right gauge based on the specific application. It is also important to ensure that all other components of the electrical system are rated to handle the same amount of current as the wire. By following these guidelines, you can ensure a safe and reliable electrical system in your home.
