Landscape Lighting Wire Runs

Have a voltmeter on hand to help anticipate voltage drop especially in systems with more than 10 lights or for systems with wire runs longer than 100 feet.

Landscape lighting wire runs. You are to add all available light wattages plus 20 for reliability. Voltage Drop Equation For Landscape Lighting. Landscape lighting cables connect the transformer to the fixtures.

The lower the gauge the thicker the wire will be. 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. Maximum number of fixtures 2 using the Daisy Chain wire method.

If the majority of your light fixtures are at the far end of the run multiply the voltage drop by 15 150. Voltage drop is the amount of voltage lost due to resistance in the wire. Here are the links for wate.

See below for acceptable voltages for LED and typical incandescent landscape lighting systems. To control voltage drop in low-voltage landscape lighting systems there are two things to consider. Maximum of 180 watts per each 12-2 gauge wire run.

We recommend 12-gaugeor 10-gauge wire for long distances. We will compare the most common wiring methods below but before we do that lets consider the nemesis of wiring any landscape lighting system. Voltage is the remaining voltage after voltage dropis subtracted out.

Output from the transformer. Distance of the wire run. Use this voltage drop equation to figure out how many volts your wire will lose over a distance.
