Wiring Tutorial
Wiring Your Landscape Lighting System and Fixtures - Since we are solely focused on Low Voltage LED Landscape Lighting in our DIY tutorial, we will only be focused on Low Voltage systems for the wiring illustrations. There are a few unique characteristics of low voltage wiring systems that differentiate from standard 120V household wiring.
Generally speaking there is no polarity in the majority of Low Voltage Landscape Lighting fixtures, so unlike installing a new light fixture at home there is no difference between the wires (no black and white to keep track of), and there is also no ground wire on the fixtures.
​
Generally most Landscape Lighting fixtures are installed in daisy chain format with fixtures being installed from one light to another down the line. It's also common for light to installed in groups by creating a T intersection at some point in the system.
​
Overview
The illustration shows a typical wiring configuration for a Landscape Lighting system followed by detailed illustrations of the wiring methods.
As you can see we've highlighted three areas that we will illustrate in more detail below.
A) Wiring of a Single Landscape
Lighting Fixture in a series of lights
When installing a Low Voltage Landscape Lighting fixture inline you generally will have three wire ends to connect together for each conductor (one from the fixture, one from the power source and one to the next fixture). As we mentioned previously with Low Voltage Lighting either conductor can be used (there is no black and white to worry about).
B) Creating a "T" Junction for Wiring a Landscape Lighting System
There will often be instances in a Landscape Lighting System where it's not possible or practical to have all fixtures installed inline where a T Junction is necessary. In our sample system a good example of this would be the stair area. As with wiring a fixture inline the main power wire is cut and the three conductors are connected together with silicone filled wire nut.
C) Fixtures installed at the end of the Landscape Lighting System
Lastly we have fixture that will be installed at the end of the line or wire. Fixtures at the end of your system will just have connections from the fixture to the end of the wire using a silicone filled connector nut. We have covered the basics for installing a landscape lighting system!
