Hubbell 71020NP Locking Plug Non-metallic L10-20P

Product Description

The HUBBELL 71020NP is a non-metallic locking plug configured to the NEMA L10-20P twist-lock standard. It is designed for use in applications requiring a secure, vibration-resistant electrical connection that cannot be accidentally disconnected. The L10-20P configuration supports 20-amp, 125/250-volt service, making it suitable for demanding power distribution tasks in commercial and industrial settings. Licensed electricians and facilities maintenance technicians are the primary installers of this device.

This locking plug is used in commercial buildings, industrial facilities, and job-site power distribution where a reliable, non-permanent wiring connection is needed. The non-metallic housing reduces weight and provides corrosion resistance in environments where moisture or chemical exposure may be present. Typical applications include portable generators, power distribution panels, and cord-and-plug connected equipment operating on split-phase circuits.
