14/2 Vs 12/2 Landscape Wire: Which One Should You Use?


If you’re planning to install landscape lighting or sprinkler systems in your yard, you’ll need to choose the right wire. Two of the most common options are 14/2 and 12/2 landscape wire. Both are suitable for outdoor use, but they have some key differences that you should know about. In this article, we’ll compare the two and help you decide which one is best for your needs.

What is Landscape Wire?

Landscape wire is a type of electrical wire that’s designed for outdoor use. It’s typically used to power lighting fixtures, sprinkler systems, and other outdoor electronics. Landscape wire is designed to be weather-resistant and durable, so it can withstand exposure to rain, wind, and sunlight.

14/2 Landscape Wire

14/2 landscape wire is a type of wire that consists of two insulated conductors that are 14-gauge thick. It’s a common choice for low-voltage outdoor lighting systems. The 14-gauge thickness is suitable for shorter wire runs and lower wattage loads. This wire is often used for smaller projects or areas where the distance between the transformer and the fixtures is shorter.

12/2 Landscape Wire

12/2 landscape wire is a thicker wire than 14/2, with two insulated conductors that are 12-gauge thick. This wire is suitable for longer wire runs and higher wattage loads. It’s often used for larger lighting systems or sprinkler systems that require more power. The 12-gauge thickness allows for less voltage drop over longer distances.

Which One Should You Use?

The choice between 14/2 and 12/2 landscape wire depends on your specific needs. If you’re installing a small lighting system or only need to power a few fixtures, 14/2 wire may be sufficient. However, if you’re installing a larger system or need to power a sprinkler system, 12/2 wire is the better choice.

Consider the Distance

Another factor to consider is the distance between the transformer and the fixtures. If the distance is short, 14/2 wire may be suitable. However, if the distance is longer, 12/2 wire will help prevent voltage drop and ensure that the fixtures receive enough power.

Consider the Wattage

You should also consider the wattage of the fixtures you’re planning to use. If you’re using fixtures with higher wattage, 12/2 wire will be necessary to provide enough power. However, if you’re only using lower wattage fixtures, 14/2 wire may be sufficient.

Installation Tips

Regardless of which wire you choose, there are some installation tips you should keep in mind. First, make sure the wire is buried underground to protect it from damage and keep it out of sight. Second, use waterproof connectors to join the wires and protect them from moisture. Finally, make sure the wire is connected to a GFCI outlet to prevent electrical shock.


Choosing the right landscape wire is essential for a successful outdoor lighting or sprinkler system installation. 14/2 wire is suitable for smaller projects or shorter distances, while 12/2 wire is necessary for larger projects or longer distances. Consider the wattage of your fixtures and follow proper installation techniques to ensure a safe and reliable system.
