Electrical — FAQ
What's the difference between 10-gauge and 12-gauge cords?
10-gauge handles 15-20 amps with less voltage drop over distance—critical for heavy tools. 12-gauge suits most 15-amp tools up to 50 ft but loses power faster at longer runs.
Can I leave heavy-duty cords outdoors permanently?
No. Even weatherproof cords degrade from UV exposure. Store indoors after use; for permanent outdoor power, install GFCI outlets instead of relying on extension cords.
Why do some cords have lighted ends?
The indicator confirms live power without testers—essential for safety in dark conditions. Ensure lights are LED-based to avoid adding significant load to the circuit.
How do I prevent tripping hazards with long cords?
Use cord ramps for walkways and secure runs with nylon straps—not nails or staples. Keep excess coiled loosely to avoid heat buildup from tight loops.
Are yellow cords more durable than orange?
Color doesn't indicate strength. Focus on jacket material (SJTW for outdoors) and AWG rating. Yellow is standard for construction sites for high visibility in debris.
Can I plug two heavy-duty cords together?
Avoid daisy-chaining—it increases fire risk and voltage drop. For extended reach, use a single cord rated for the total length, or install a temporary power station at midpoint.
