5 Things to Know About 14/3 Wire for Outdoor Lighting

14/3 wire works for nearly all outdoor lighting It is rated for 15 amps, which is more than enough for most setups like string lights, path lights, or low-voltage fixtures.

A long string of Edison bulbs pulls only 3-4 amps Even a lengthy run of those bulbs stays well within the 14/3 wire’s capacity.

Only upgrade to 12/3 for very long runs If your wire run exceeds 100 feet, voltage drop may require thicker 12/3 wire.

High-wattage floodlights also need 12/3 Running powerful floodlights or other high-wattage fixtures may exceed what 14/3 can handle.

14/3 is the standard choice for most homeowners Unless you have an unusually long run or high power demands, 14/3 is sufficient and easier to work with.
