what wire for recessed lighting

Recessed lighting is one of the most popular options for illuminating a home. From accentuating artwork to brightening up a kitchen, recessed lighting can do it all. But when it comes to selecting the right wire, how do you know where to begin?

Choosing the correct wire for recessed lighting can be daunting. Not only do you need to consider factors such as wattage and lumens, but you must also select the adequate gauge according to code. To simplify the process, it helps to understand the basics of recessed lighting wiring and the different types of wiring available. Here's everything you need to know about wiring for recessed lighting.

When it comes to wiring for recessed lighting, the most important factor to consider is the gauge of the wire. The National Electric Code requires all wiring to be 14-gauge or larger (for 120-volt circuits). This means that if you are dealing with a 15-amp circuit, the minimum gauge required is 14. For 20-amp circuits, the required minimum is 12-gauge. It's important to check the amperage of your circuit before selecting the appropriate gauge.

When wiring recessed lighting, safety is paramount. If the wiring is not installed properly, it can lead to electrical fires, shock, and other potential hazards. To ensure your wiring is up to code, it is best to consult with a professional electrician. They will be able to provide you with the necessary advice and expertise to ensure proper installation.

In addition to selecting the right gauge for your wiring, you'll also need to decide between two types of wiring: Romex and Non-metallic Sheathed Cable (NM). Romex is a type of non-metallic sheathed cable that has three conductors and a ground. It is the most common type of wiring for residential applications and has been approved by the NEC for use in wet locations. NM cable is also a type of non-metallic sheathed cable and is typically used for commercial applications. Although it is allowed to be used in wet locations, it is not approved by the NEC.

When selecting the appropriate wiring for recessed lighting, it is important to consider the environment in which it will be used. Romex is the best option for use in damp locations, while NM cable should be used in dryer areas. Additionally, if your recessed lighting will be exposed to direct sunlight, make sure to use a UV-resistant jacketed cable. This will help to ensure that the wiring is protected from the sun's rays, which can deteriorate the insulation over time.

When installing recessed lighting, it's best to opt for a shorter run of wire. Longer runs of wire can cause voltage drop, which can affect the performance of your lights. To prevent voltage drop, use a higher gauge of wire and make sure to have a professional electrician install it.

Finally, it's important to consider the type of fixtures you are using when selecting the appropriate wire for recessed lighting. Some fixtures require a specific type of wire, so it is important to read the manufacturer's instructions to ensure you are using the correct wire.

To summarize, when selecting the right wiring for recessed lighting, you'll need to consider several factors. First, choose the appropriate gauge of wire according to code and the type of circuit. Next, decide between Romex and NM cable based on the environment in which it will be used. Finally, consider the type of fixture you are using to ensure you are using the correct type of wire. By taking the time to understand the basics of recessed lighting wiring, you can ensure your wiring is safe and up to code.
