Landscape lighting wire size chart. Wire is sized by the american wire gauge awg system. Voltage drop equation for landscape lighting. The wire comes in different sizes such as 8 10 12 14 16 and 18. Over 200 watts you should use a 12 gauge sized wire.

Low voltage landscape wiring or electrical cable comes in several numerical gauges or sizes. A lower number means thicker wire and greater capacity to carry the power current for longer distances. 12 and 16 gauge. We recommend 12 gauge or 10 gauge wire for long distances.

Transformers generally range from 150 to 900 watt capacity. The pvc jacket resists damage from uv exposure for durability and the wire is suitable for direct burying. Another way to counteract a high voltage drop is change to a thicker wire such as 10 guage. Common wires for landscape lighting are 10 12 14 or 16 gauge wires.

It can also be used in security applications. Total watts on low voltage wire length of wire run in feet wire size constant listed in chart below voltage drop. Here is a chart to determine the maximum wattage allowed for each buried wire. Black 12 2 landscape wire this cerro 500 ft.

Our low voltage landscape lighting calculator will allow you to enter this information to determine the maximum distance from the transformer to the lights. 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. Common sizes include 14 12 10 8 6 and 2 gauge wire. A good rule of thumb for selecting proper wire size is determining your wattage.

Watts wire run length constant voltage drop. This cerro 500 ft. The maximum wire run distance from the transformer to the lights will depend on several factors. Landscape lighting wire low voltage landscape lighting wire or landscape lighting cable as it is often referred as is made of multi strands of copper wire that are bound together.

Were as a 120 volt line voltage wire is a single strand wire. 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. Any system under 200 watts will be fine using 16 gauge wire. Black 12 2 landscape wire is designed for landscape and outdoor accent lighting applications.

Wire size wattage of lights and length of run. Most low voltage landscape lighting wire comes in two different sizes.
