14/2 Romex For Lights

When it comes to electrical wiring, choosing the right type of cable can make a big difference. One of the most popular cables for lighting circuits in homes and buildings is 14/2 Romex. But what exactly is 14/2 Romex, and why is it so commonly used for lighting? In this article, we’ll provide everything you need to know about this type of cable and its benefits.

What is 14/2 Romex?

First, let’s break down the name. “14” refers to the gauge of the wire inside the cable, which is commonly used for branch circuits that support up to 15 amps. “2” refers to the number of wires inside the cable, which includes a black (or sometimes red) wire for hot, a white wire for neutral, and a bare or green wire for ground. “Romex” is a brand name for a type of non-metallic sheathed cable (NM) that’s commonly used for residential electrical applications.

Why Use 14/2 Romex for Lighting?

1. Cost-effective

One of the main reasons 14/2 Romex is popular among contractors and electricians is that it’s relatively inexpensive compared to other types of electrical cable. This is because the wire inside the cable is made from copper, which has become increasingly affordable in recent years due to abundant global supply. In addition, the non-metallic sheathing is easy to manufacture and transport, further reducing the cost.

2. Convenient and Easy to Install

Another reason 14/2 Romex is a popular choice is because it’s easy to install. The cable comes in rolls of various lengths, and the smaller gauge (14) makes it more flexible and easier to work with in tight spaces. The cable can be run through walls, ceilings, and floors using staples or cable ties, and can be cut to the desired length without the need for conduit.

3. Suitable for Residential Applications

Because 14/2 Romex is a type of non-metallic sheathed cable, it’s well-suited for residential applications like lighting circuits. This is because the cable’s insulation doesn’t contain any metal, which can help reduce the risk of electrical shock in the event of an accident or malfunction. In addition, the cable’s sheathing is usually made from PVC, which is durable and resistant to moisture and temperature changes.

4. Can Support Up to 15 Amps

Another advantage of 14/2 Romex is that it’s capable of supporting up to 15 amps of electrical current, which is typically more than enough power for most lighting circuits. This means that the cable can safely support a number of light fixtures, switches, and other components without the risk of overheating or overloading the circuit.

5. Safe and Reliable

Finally, 14/2 Romex is a safe and reliable option for lighting circuits because it’s tested and certified to meet national safety standards. In the United States, the cable must meet the standards of the National Electric Code (NEC), which defines the minimum requirements for safe electrical installations. The NEC specifies the type of cable, conductor size, and spacing of fixtures, among other important factors.


In conclusion, 14/2 Romex is a popular and cost-effective choice for lighting circuits in homes and buildings. Its flexibility, affordability, and ease of installation make it a favorite among electricians and contractors, while its safety and reliability ensure that it meets the highest standards of electrical safety. If you’re planning to install a new lighting circuit in your home or building, consider using 14/2 Romex as a reliable and cost-effective option.
