Overview
When reliable, watertight power is mission-critical, the Leviton Wetguard Watertight Locking Plug ensures continuous, secure service in the toughest environments. This industrial-grade connector (NEMA L17-30) delivers 30A at 600V with 3-pole, 4-wire grounding to power generators, distribution panels, and critical security equipment. Its IP69K-rated Wetguard housing and tongue-and-groove sealing protect connections from high-pressure, high-temperature washdowns, chemicals and debris — preventing corrosion and costly downtime.
Designed for demanding applications like surveillance, monitoring, data center temporary power, and industrial automation, the locking mechanism provides a vibration-resistant connection so cameras, access control and network devices stay online. Heavy-duty one-piece contacts mean better conductivity and lower heat rise under load, while the bright yellow color aids quick identification during installations and service. Backed by Leviton’s lifetime warranty, this connector reduces lifecycle costs and maintenance interruptions. Upgrade your power infrastructure with a watertight, industrial locking plug engineered for safety and long-term reliability — ideal for security, surveillance and industrial power needs.
