What Gauge Wire To Use For Landscape Lighting

It would be technically ok current wise for 120vac but i don t know of any 16ga wire rated for distribution outdoors.

What gauge wire to use for landscape lighting.

This is to prevent voltage drop. Awg 14 wire is rated for 15a awg 16 wire is rated for 8a so if you are using a 12 v power pack 16ga is too small. This is to prevent voltage drop. Split the run into 2 runs and recalculate.

Common wires for landscape lighting are 10 12 14 or 16 gauge wires. In this technique a home run from the transformer is brought to the center fixture of a group that typically uses 12 gauge or larger wire. Over 200 watts you should use a 12 gauge sized wire. Http lightingdoctor ca learn how to wire low voltage landscape lighting with an easy to follow wiring diagram demonstration.

A good rule of thumb for selecting proper wire size is determining your wattage. The run is connected in a t formation to a balanced number of fixtures on each side usually no more than five lower wattage fixtures. Common wires for landscape lighting are 10 12 14 or 16 gauge wires. The further you get from the transformer and its power supply the more resistance occurs in the circuit which causes the voltage to decrease.

12 and 16 gauge. The lower the gauge the thicker the wire will be. Any system under 200 watts will be fine using 16 gauge wire. For led light strips used to illuminate your layout room i too would go with no lighter than 18 gauge.

Most low voltage landscape lighting wire comes in two different sizes. The gauge number determines the thickness of the 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. The most common landscape lighting wire that you will use in your landscape lighting is 12 2 for longer runs of wiring you can use a 10 or even a 8 landscape wire.

We recommend 12 gauge or 10 gauge wire for long distances. Also remember when figuring wattage consumed on a run make sure to always calculate the highest wattage lamp that each fixtures can handle.
