Hubbell HBL2621 Twist Lock Plug Nema L6-30 250V 30A

Product Description

The HUBBELL HBL2621 is a NEMA L6-30 male twist lock plug rated for 250 volts and 30 amps in a 2-pole, 3-wire single-phase configuration. Built with black and white nylon construction, this plug is designed to provide a secure, twist-locking electrical connection in demanding trade environments. The Insulgrip body design supports cord diameters from 0.36 inches to 0.93 inches, accommodating a wide range of cable gauges. Electricians rely on this plug for branch circuit terminations where a positive locking connection is required to prevent accidental disconnection under load.

The HBL2621 is suited for commercial and industrial electrical installations where NEMA L6-30 receptacles are specified. Typical applications include generator connections, portable power distribution equipment, HVAC equipment hookups, and high-draw single-phase loads operating at 250 volts. The twist lock design makes it appropriate for environments where vibration or movement could cause a straight-blade plug to disengage. It is installed by licensed electricians working on branch circuits requiring a 30-amp, 250-volt locking termination.
