14-2 Amperage Rating

14-2 Amperage Rating: Everything You Need to Know

When it comes to electrical wiring, one of the most important things to consider is the amperage rating. The amperage rating refers to the maximum amount of current that a wire can handle before it becomes overheated and poses a fire hazard.

One common type of wiring that you may encounter in residential and commercial settings is 14-2 wiring. In this article, we’ll take a closer look at 14-2 amperage rating, what it is, how it’s used, and some of the important considerations to keep in mind when working with this type of wiring.

What is 14-2 Wiring?

Before we dive into the amperage rating of 14-2 wiring, let’s first define what it is. 14-2 wiring refers to a two-conductor cable with a 14-gauge conductor and a ground wire. The cable contains two insulated conductors and a ground wire that is uninsulated. The insulation on the conductors is color-coded, with one being black or red, and the other being white.

This type of wiring is commonly used for a variety of applications, including lighting and electrical outlets. It’s also used in many small appliances and electronics, such as power tools, microwaves, and coffee makers.

What is the Amperage Rating of 14-2 Wiring?

The amperage rating of 14-2 wiring is typically around 15 amps. This means that the wire can handle a current of up to 15 amps without becoming overheated and posing a fire hazard.

It’s important to note that the amperage rating of a wire is often dependent on a number of factors, including the length of the wire, the temperature of the environment, and the type of insulation used. As such, it’s important to consult the manufacturer’s specifications when determining the amperage rating of a particular wire.

What are the Uses of 14-2 Wiring?

Because 14-2 wiring has a relatively low amperage rating, it’s typically used for low-load applications. Some of the most common uses of 14-2 wiring include:

– Lighting: 14-2 wiring is often used for lighting fixtures and other low-load lighting applications in residential and commercial settings.
– Outlets: 14-2 wiring can also be used for electrical outlets, as long as the devices plugged into them don’t draw a high amount of current.
– Small Appliances and Electronics: Many small appliances and electronics, such as power tools and microwaves, use 14-2 wiring for their power cords.

Factors to Consider with 14-2 Wiring

While 14-2 wiring is a common choice for many low-load applications, there are a few important factors to consider when using this type of wiring:

– Length of the Wiring: The longer the wire, the more resistance it will have, which can lead to a voltage drop. If you’re working with 14-2 wiring over long distances, it’s important to factor in this voltage drop and potentially use a thicker wire.
– Environment: The environment in which the wiring will be used can also impact the amperage rating. For example, if the wiring will be exposed to high temperatures, the insulation may break down faster, lowering the amperage rating.
– Circuit Breakers: To ensure proper safety, it’s important to connect 14-2 wiring to appropriate circuit breakers that can handle the load. If a higher load is needed, it’s important to upgrade to a thicker wire that can handle the current.


Q: Can I use 14-2 wiring for a 20-amp circuit?

A: No, it’s not recommended to use 14-2 wiring for a 20-amp circuit. The amperage rating of 14-2 wiring is typically around 15 amps, and it’s important to use appropriate wiring for the circuit breaker to avoid hazards such as overheating or fires.

Q: How do I know if 14-2 wiring is right for my application?

A: The best way to determine the right type of wiring for your application is to consult the manufacturer’s specifications or a professional electrician. Factors such as the load, length of the wire, and environment all play a role in selecting the appropriate wiring.

Q: Can I install 14-2 wiring myself?

A: While it’s possible to install 14-2 wiring yourself, it’s important to have a basic understanding of electrical safety and ensure that the wiring is installed correctly. If you’re unsure about your ability to install wiring, it’s recommended to consult a licensed electrician.


While 14-2 wiring may not be the best choice for high-load applications, it’s a popular choice for many low-load applications in residential and commercial settings. Understanding the amperage rating and other important factors can help ensure that you use this type of wiring safely and effectively. If you’re unsure about how to use 14-2 wiring or have any questions, it’s always best to consult a professional electrician.
