Leviton Telcom 26W81 Locking Plug 4P5W L21-20P

Product Description

The LEVITON TELCOM 26W81 is a yellow locking plug rated for 4-pole, 5-wire, 3-phase wiring in a NEMA L21-20P configuration. Locking plugs of this type are used in industrial and commercial electrical distribution where a secure, twist-lock connection is required to prevent accidental disconnection under load. The L21-20P designation indicates a 20-amp, 3-phase wye configuration with a ground, making it suitable for demanding power distribution applications. Electricians and electrical contractors install this plug when connecting portable equipment or temporary power drops to matching L21-20R receptacles.

This plug is designed for use in commercial and light industrial settings where 3-phase power distribution is required. Typical applications include connecting portable power tools, generators, temporary distribution panels, and other 3-phase equipment to twist-lock wiring systems. The yellow housing provides a visual indicator commonly associated with specific voltage classifications in color-coded wiring systems, aiding identification in multi-outlet panel setups and helping reduce mis-connection errors on the job.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before disassembling or installing any locking plug. Verify that the receptacle configuration, voltage, and amperage match the plug rating before making connections. Do not exceed the rated amperage of the plug or the connected circuit.
