What Type Of Cable For Outdoor Lighting

When it comes to outdoor lighting, choosing the right type of cable is essential for ensuring safety, durability, and performance. With so many different types of cables available, it can be overwhelming to know which one is best for your needs. In this article, we'll explore the key factors to consider when selecting a cable for outdoor lighting and provide guidance on the different types of cables available.

Factors to Consider

Voltage: The voltage of your lighting system will determine the type of cable you need. Most outdoor lighting systems operate on 12 volts or 120 volts. Make sure the cable you choose is rated for the voltage of your system.
Amperage: The amperage of your lighting system will determine the size of the cable you need. The amperage is the amount of current that will be flowing through the cable. Make sure the cable you choose is rated for the amperage of your system.
Length: The length of the cable you need will depend on the distance between your light fixtures and your power source. Make sure the cable you choose is long enough to reach all of your light fixtures.
Environment: The environment in which your cable will be installed will also affect the type of cable you need. If your cable will be exposed to the elements, you'll need to choose a cable that is rated for outdoor use. If it will be installed underground, you'll need to use a direct burial cable.

Types of Cables

There are several different types of cables that can be used for outdoor lighting. The most common types include:

Non-Metallic (NM) Cable: NM cable is a type of low-voltage cable that is commonly used for indoor and outdoor lighting. It is made up of two or more insulated conductors that are wrapped in a plastic jacket. NM cable is not rated for direct burial, so it must be installed in a conduit or raceway if it will be exposed to the elements.
Underground Feeder (UF) Cable: UF cable is a type of direct burial cable that is designed for use underground. It is made up of two or more insulated conductors that are wrapped in a moisture-resistant jacket. UF cable is rated for both indoor and outdoor use.
Armored Cable (AC): AC cable is a type of cable that is protected by a metal armor. The armor helps to protect the cable from damage caused by impact, abrasion, and moisture. AC cable is often used in commercial and industrial applications.

Choosing the Right Cable

Once you've considered the factors above, you can choose the right type of cable for your outdoor lighting needs. Here are some general guidelines:

For low-voltage lighting systems (12 volts), NM cable or UF cable is a good choice.
For high-voltage lighting systems (120 volts), UF cable or AC cable is a good choice.
For underground installations, UF cable is the best choice.
For installations that will be exposed to the elements, AC cable is the best choice.

By following these guidelines, you can choose the right type of cable for your outdoor lighting needs and ensure that your system is safe, durable, and performs well for years to come.
