Voltage Drop & Wire Gauge Distance Chart
“Voltage drop” is a gradual lessening of power through a wire over a long distance. The farther the light fixture is from the power
source, the more voltage drop will occur. Voltage drop becomes a significant factor in any LED light installation when the distance
between the lights and the power source is greater than 20 feet.
To minimize voltage drop, you can:
1. Use a thicker gauge wire (the lower the number, the heavier and thicker the wire) between
the 12V-24V driver and the light.
2. Use multiple smaller power sources throughout a large installation.
3. Place the 12V-24V driver closer to the 12V-24V light by extending the wiring between 120V
house power and the 12V or 24V driver, rather than between the 12V-24V driver and the light.
For optimum results, consult a qualified, licensed electrician prior to installation.

For an installation that follows option 1 above, determine what gauge wire (AWG) you will need to prevent voltage drop by consulting
the chart below. The recommendations in this chart are based on accepted standards to prevent a voltage drop greater than 10%.
In order to ensure the full lamp life of an LED light fixture, always supply the full 12V or 24V DC power. Note: Be sure to observe the
run limits recommended for each strip light as detailed on the strip light’s product page, as exceeding these limits will also result in
voltage drop.
