Overview
The Leviton 2311 is an extra heavy-duty, industrial-grade locking plug designed for safe and secure temporary power connections. Featuring NEMA L5-20P configuration with 2-pole, 3-wire grounding capability, this plug accommodates 20-amp loads at 125 volts. The polarized design ensures proper wiring orientation, while the rivetless, single-piece brass contacts eliminate friction and potential overheating concerns in demanding industrial settings.
