Landscape Wire

Landscape wire is direct burial low voltage cable that carries 12V power from the transformer to each landscape fixture. This category covers the common gauges of landscape wire sized to run length and load so fixtures hold their brightness.

Landscape Wire Selection Guide

Wire gauge is the quiet decision that makes or breaks a landscape system, because a run that is too long on wire that is too light dims every fixture at the end. Landscape wire is part of the Landscape Lighting Accessories family alongside Landscape Transformers, serving all the fixtures in Landscape Lighting such as Landscape Path Lights.

Match the Wire Gauge to the Run

Heavier gauge carries power farther with less voltage drop. Match the gauge to the load and the distance.

Voltage Drop and Run Planning

Voltage drop is the enemy of even brightness: the farther power travels and the more fixtures it feeds, the more voltage is lost along the way. A heavier gauge loses less, which is why long main runs use 10 or 12 AWG. Splitting a layout into multiple runs from the transformer, or using a hub, shortens each run and keeps the far fixtures as bright as the near ones. A multi-tap transformer compensates for the drop that remains.

Burial, Connections, and Rating

Use wire rated for direct burial so it survives in the ground without conduit, and bury it to a safe depth below where a shovel or edger will reach. Join wire to fixtures with waterproof, direct burial rated connectors, not the pierce point clips that corrode underground. Size the wire with the transformer and the fixture load together, which the Landscape Lighting Accessories category covers.

Frequently Asked Questions About Landscape Wire

Match the gauge to the run length and the total fixture load. Long main runs and higher loads use 10 or 12 AWG, shorter runs use 14 AWG, and 16 AWG suits only short taps with few fixtures. Heavier gauge loses less voltage over distance.

Voltage drop is the loss of voltage as power travels along the wire. The farther the run and the more fixtures it feeds, the more voltage is lost, which dims the far fixtures. Heavier wire, shorter runs, and a multi-tap transformer reduce it.

Yes. Landscape wire rated for direct burial is designed to go in the ground without conduit. Bury it to a safe depth below where a shovel or edger would reach to protect it.

Use waterproof, direct burial rated connectors at each fixture. Avoid the pierce point clips included in some kits, since they corrode and fail underground. Good connectors are a key reliability upgrade.

Several shorter runs from the transformer, or a hub, keep each run short and the voltage even, so the far fixtures stay as bright as the near ones. One long run invites voltage drop at the end.

Size the wire and transformer together. The transformer must supply the total load, and the wire gauge must carry that load over the run without excessive drop. A multi-tap transformer compensates for the drop that remains.
