18 AWG cord guidelines
Maximum run: 250 feet or less on 18 AWG cord, including extension cords and branches. With C9 incandescent bulbs, the maximum is 200 feet.
Match the plug to the insulation: SPT-1 cord takes an SPT-1 Gilbert plug, and thicker SPT-2 cord takes an SPT-2 plug.
Total load: up to 10 amps / 1200 watts for 18 AWG cord.
Helpful Tips
SPT-1 vs. SPT-2: SPT-1 and SPT-2 is a measure of the insulation thickness of traditional 18 AWG cords. SPT-1 is the type most commonly used by commercial Christmas lights installers. SPT-2 is thicker and tailored to harsh weather conditions. Gilbert plugs must match.
