A 240V ballast power cord connects a 240-volt ballast (used for indoor grow lights) to a 240V wall outlet. It features a 240V male plug on one end (typically NEMA 6-15P) and a female connector on the other end for the ballast (often a C13 connector). The cord is designed for 240V power, typically made with heavy-duty, flexible, and durable materials like 100% copper wiring within a SJTW or SJT PVC cable.
