Locking plug
Watertight locking plug design delivers IP67 protection, protecting terminations from moisture and dust in wet or dusty environments; this reduces unplanned downtime and improves equipment reliability in manufacturing and processing plants. Back wiring support for #18-10 AWG simplifies field terminations, minimizes wiring errors, and shortens installation time, delivering measurable labor savings and more consistent connections in panel assemblies. The four-pole, four-wire configuration operates at 347/600 V with a 20 A rating and a NEMA L20-20 layout, enabling reliable three-phase power delivery to motors and control gear in harsh conditions. Nickel-plated brass contacts offer corrosion resistance and stable electrical performance, while Santoprene seals and a Nylon body provide lasting mechanical integrity and chemical resilience in demanding environments. The cord-diameter range of 0.36–0.84 in supports diverse cord sets, ensuring a tight seal and repeatable engagement even in vibratory applications. Compliance with RoHS and cULus reduces regulatory risk and streamlines procurement, while the locking mechanism minimizes accidental disconnections in installations with motion or vibration.

FAQs
Yes, L2020PWBK supports back-wiring with #18-10 AWG conductors. It uses a torque range of 14-16 lbf-in to ensure a secure, repeatable connection without over-tightening, which helps prevent conductor damage and maintains voltage integrity in vibration-prone equipment.
The L2020PWBK is rated for 20A at 347/600 V and configured as NEMA L20-20. It provides four poles with four wires (non-grounding) and is designed for three-phase industrial power distribution in demanding environments.
This locking plug excels in industrial panels, motors, and control cabinets exposed to moisture, dust, or vibration. Its IP67 sealing, back-wiring capability, and robust construction make it suitable for manufacturing, material handling, and outdoor equipment installations.
The L2020PWBK is RoHS compliant and cULus listed, confirming conformance to environmental and safety standards. Its IP67 rating also supports compliance with ingress protection requirements in harsh environments.
The combination of nickel-plated brass contacts, Santoprene sealing, and a Nylon body delivers durable electrical performance with resistance to corrosion and seals that maintain integrity over time. This reduces maintenance cycles, lowers replacement costs, and improves overall uptime for critical industrial equipment.
