NEMA 5-20 Extension Cord, 5-20P Male Plug to 5-20/5-15R Female Receptacle, 20 Amp T-Blade Outlet Custom Extension Power Cord

  • 20-Amp High-Capacity Power: Rated for 20A / 125V / 2500W, this cord handles heavy loads that standard 15A cords cannot, making it ideal for power tools, workshop machinery, and commercial equipment.
  • NEMA 5-20P “T-Blade” Plug: The unique T-shaped blade plug is designed to fit into dedicated 20-amp outlets, ensuring a secure connection for high-power applications.
  • Versatile Dual Receptacle: The female end features a NEMA 5-20R receptacle that can power a 20-amp device, plus a standard NEMA 5-15R outlet for simultaneous use of a standard 15-amp plug. This dual-functionality maximizes utility.
  • Fully Customizable Length & Color: Specify the exact length you require for your application, from a short patch cord to a long run. Choose a color for safety visibility (e.g., bright orange) or to blend with your environment.
  • UL Listed for Safety: This cord is UL Listed, meeting rigorous safety standards for electrical construction, performance, and durability. This is a non-negotiable feature for professional and demanding environments.
  • Robust Construction: Built with a heavy-duty jacket (e.g., STW, SJTW) that is resistant to oil, abrasion, weather, and physical damage, ensuring longevity in tough conditions.
  • Superior Conductors: Utilizes thicker 12 AWG copper wiring to minimize voltage drop over longer distances and prevent overheating under full 20-amp load.

NEMA 5-20P to 5-20R/5-15R T-Blade Outlet Custom Extension Power Cord

This is a durable, UL-listed heavy-duty extension cord featuring a NEMA 5-20P male plug (3-prong grounded with T-shaped hot blade for 20A circuits) connected to a NEMA 5-20/5-15R female receptacle (T-slot outlet compatible with both 20A T-blade and standard 15A plugs). It’s designed for safely extending power in high-amperage 120V applications, such as workshops, garages, kitchens, or job sites, where devices like power tools, welders, or commercial appliances need reliable reach without voltage drop. The T-blade configuration ensures secure connections on 20A circuits, while the female end accepts mixed plug types for versatility. Fully customizable for length (e.g., 1-100 feet), color (e.g., yellow for visibility, black for aesthetics, or Pantone-matched), and packaging (e.g., retail coils, bulk spools, or branded clamshells). UL Listed certification (Underwriters Laboratories) verifies compliance with safety standards like UL 62 for flexible cords, including grounding integrity and flame-retardant materials, making it suitable for temporary or semi-permanent use.Key Use Case: Plug the 5-20P male end into a 20A wall outlet or generator, then connect tools or appliances with 15A or 20A plugs to the 5-20/5-15R female end—ideal for custom OEM orders in construction, HVAC, or event production where specific lengths and colors match site branding.
