20A Heavy-Duty Power Handling: Engineered for 20A/125V circuits, this industrial-grade plug set delivers 33% more power capacity than standard 15A models. Perfect for generators, RVs, welding equipment, and handling heavy loads that standard 15A plugs cant support. NOTE:The NEMA 5-20P plug must connect to a 20A transfer switch. The NEMA 5-20R receptacle with T-rating is compatible with both NEMA 5-15P and NEMA 5-20P plugs.
