Why each option
The NEMA L6-50 is a locking power connector rated for 250V AC at 50 amps, commonly used in data center and high-powered server rack environments.
-48V DC is a telecom industry standard voltage associated with DC power distribution systems and is not part of the NEMA L6 locking connector series, which is designated exclusively for AC circuits.
120V AC corresponds to the NEMA L5 series of locking connectors (e.g., L5-20, L5-30), not the L6 series, which is a distinct voltage class reserved for 250V AC.
The NEMA L6 series designation specifies 250V AC circuits, and the '50' suffix indicates the 50-ampere current rating, making L6-50 a 250V AC, 50A locking receptacle. This connector type is standard in data center environments where servers require higher voltage AC power than typical 120V branch circuits.
4400V AC is a utility-level transmission voltage not associated with any NEMA receptacle standard used in server room or data center rack power distribution.
