What Size Landscape Lighting Wire

Most people would likely recommend using a solid core 18-gauge wire for your LED lights.

What size landscape lighting wire. We recommend 12-gauge or 10-gauge wire for long distances. To bury the wires where they cross the lawn use a flat-nosed shovel to cut a slot and fold back the sod. Lets take a look at some different wiring techniques and the good and bad of each of them.

In the hub technique a home run is brought from the transformer to a location within a cluster of fixtures. Besides the gauge size plays a huge role when calculating the maximum voltage drop. You will often see landscape lighting wire called 122 or 102 the 2 stands for conductors which is the number of wires inside the outer insulation.

100 watts of lights at the end of a 200ft wire run on a 102 wire. Long distances that exceed 300 ft. Use 10-gauge wire for the main lines from the transformer to where the lights begin then switch to 12-gauge wire between the lights.

It is always a good idea to stay away from long runs of smaller 142. The lower the gauge the thicker the wire will be. Measure the total lengths per wire run.

This wire size is capable of handling much more than your average system. How long can you run landscape wire. There are several gauge sizes that are used in landscape lighting with the most common being 10-gauge 12-gauge and 16-gauge wiring.

This method requires equal lengths of wire on all fixtures leading to a central connection point a hub. Once you have completed the design of your landscape lighting you can move on to determining what the size of your low-voltage transformer needs to be. 12 and 16 gauge.
