Buying Guide: 16/3 Extension Cord Essentials
- Length vs. voltage drop: Longer cords increase resistance. For higher-watt devices, shorter lengths can help maintain performance.
- Indoor vs outdoor ratings: Outdoor cords (SJTW or similar) are weatherproof, flame retardant, and UV resistant; indoor cords are not designed for moisture or direct exposure.
- Safety certifications: Look for ETL or cETL listings and ensure the plug and receptacle are three-prong grounded NEMA 5-15P/R assemblies.
- Gauge and ampacity: 16 AWG cords typically support up to 13A and 1625W at 125V. Do not exceed these limits with any single device.
- Durability features: Flood or moisture resistance, molded plugs, and reinforced strain relief at the plug ends enhance lifespan and safety.
- Environmental conditions: Consider cold resistance, flame retardance, abrasion resistance, and UV tolerance when selecting cords for outdoor use.
- Usage scenarios: Indoor cords excel for desks and home offices; outdoor cords suit yard tools, lights, and weather-exposed equipment.
- Storage and handling: Coil loosely, avoid kinks, and keep cords dry when not in use to extend life.
- Safety practices: Do not run cords through doorways or windows where pinching or moisture can affect the connections; never use damaged cords.
