Choose Wire Gauge Around the Complete System

Landscape-lighting wire carries low-voltage power from the transformer through the outdoor fixture layout. The best gauge depends on connected load, cable distance, and branch design. Total Light offers 10/2, 12/2, and 14/2 direct-burial options so the wire can be matched to different project demands.

As a general planning principle, heavier conductors are useful as run length and load become more demanding. 12/2 is a versatile choice for many common installations, 10/2 provides a heavier-gauge option, and 14/2 can suit compatible shorter or lighter-load runs. Final selection should be based on the actual system rather than gauge alone.

Measure the Cable Route, Not the Property

Add the distances between fixture locations, branches, turns, and the transformer—not just the straight-line dimensions of the yard. Allow extra cable for serviceable connections, and use waterproof outdoor-rated connectors wherever the direct-burial wire is spliced.

Frequently Asked Questions

What wire gauges does Total Light offer for low-voltage landscape lighting?

This collection includes 10/2, 12/2, and 14/2 direct-burial landscape-lighting wire in multiple roll lengths.

How do I choose between 10/2, 12/2, and 14/2 wire?

Consider total connected load, distance from the transformer, branch layout, and voltage-drop concerns. Heavier conductors can be useful on more demanding runs, while lighter gauges can suit compatible shorter or lighter-load layouts.

Can this landscape-lighting wire be buried directly?

Yes. The wire in this collection is designed for direct-burial low-voltage landscape-lighting applications.

Why does wire gauge matter in a low-voltage lighting system?

Cable resistance contributes to voltage drop. Gauge, run length, connected load, transformer output, and circuit layout all work together, so wire should be planned as part of the complete system.
