NEMA L21-30P Locking Power Cord XL2130P-A
This NEMA L21-30P Locking Power Cord (Model: XL2130P-A / XH2130P-A) is a heavy-duty, 5-conductor industrial-grade power cable engineered for high-reliability applications in North America. Designed with a twist-locking plug mechanism, it ensures secure, vibration-resistant connections ideal for portable generators, RVs, marine equipment, construction tools, and commercial HVAC systems. The plug conforms to NEMA L21-30P standards, rated for 30A at 277/480V AC, and is compatible with matching L21-30R receptacles. Built for durability, the cord features a rugged black thermoplastic housing and gold-plated brass blades for superior conductivity and corrosion resistance.
