Industrial Three-Phase Locking Plug

The Hubbell HBL2761 is a NEMA L19-30P locking plug rated for 30 A at 277/480V AC in four-pole, four-wire three-phase systems. It is built for industrial environments where secure, high-voltage connections are required. The twist-lock design prevents accidental disconnection under load. This device suits facility maintenance teams and electrical contractors.

Ribbed Nylon Housing With Strain Relief

A ribbed nylon housing provides impact and chemical resistance for harsh indoor environments. The cord grip accepts diameters from .350" to 1.150" and reduces strain on screw terminal connections during operation. A clear, funnel-shaped wire entry assists with terminating #16 AWG to #8 AWG stranded copper conductors. An integral dust shield covers the internal wiring chamber. The plug carries an IP20 rating for dry locations.

Verify Phase Voltage And Cord Size Before Ordering

Confirm your supply is a three-phase 277/480V AC system matching the L19-30P configuration; this plug will not fit single-phase or lower-voltage receptacles. Ensure your cable outer diameter falls within the .350" to 1.150" range and uses only stranded copper wire from #16 AWG to #8 AWG. The unit is rated for indoor dry locations with a maximum continuous temperature of 75°C and minimum of -40°C without impact. Buyers needing outdoor or wet-location ratings should look elsewhere.

Questions about this item

What NEMA locking configuration does the HBL2761 plug use, and what voltage does it support?

The plug uses an L19-30P twist-lock configuration rated for 30 A at 277/480V AC in three-phase systems.

What cable diameters and wire gauges can the HBL2761 accommodate?

It accepts cord diameters from 0.350" to 1.150" and #16 AWG to #8 AWG stranded copper wire with screw terminal connections.

How is the HBL2761 installed, and what is a common wiring mistake?

Strip wires to the correct length, insert into the funnel-shaped wire entries, and tighten screw terminals securely; a common mistake is using solid instead of stranded copper wire.
