Landscape Lighting Wire Size Chart

Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter.

Landscape lighting wire size chart.

12 and 16 gauge. We recommend 12 gauge or 10 gauge wire for long distances. Were as a 120 volt line voltage wire is a single strand wire. A lower number means thicker wire and greater capacity to carry the power current for longer distances.

Common wires for landscape lighting are 10 12 14 or 16 gauge wires. Any system under 200 watts will be fine using 16 gauge wire. Wire is sized by the american wire gauge awg system. Smaller wire sizes are usually more economical and larger wire sizes are stronger though the smaller ones will also reduce the distance of power being provided to your lights in the ground and may need a conduit to stay safe from dreaded landscaper cuts to your lighting connections.

Use this voltage drop equation to figure out how many volts your wire will lose over a distance. Here is a chart to determine the maximum wattage allowed for each buried wire. Common sizes include 14 12 10 8 6 and 2 gauge wire. If you need more voltage drop than you are getting you may change to a thinner wire such as 14 gauge but a thinner wire supports less wattage.

This is to. Our low voltage landscape lighting calculator will allow you to enter this information to determine the maximum distance from the transformer to the lights. Watts wire run length constant voltage drop. Another way to counteract a high voltage drop is change to a thicker wire such as 10 guage.

Once your landscape lighting design is complete you can figure out what size of low voltage transformer you need. It can also be used in security applications. Black 12 2 landscape wire is designed for landscape and outdoor accent lighting applications. The pvc jacket resists damage from uv exposure for durability and the wire is suitable for direct burying.

A good rule of thumb for selecting proper wire size is determining your wattage. Low voltage landscape wiring or electrical cable comes in several numerical gauges or sizes. Black 12 2 landscape wire this cerro 500 ft. Transformers generally range from 150 to 900 watt capacity.

The wire comes in different sizes such as 8 10 12 14 16 and 18. This cerro 500 ft. Wire size wattage of lights and length of run. Most low voltage landscape lighting wire comes in two different sizes.

The maximum wire run distance from the transformer to the lights will depend on several factors. Over 200 watts you should use a 12 gauge sized wire.
