Hubbell HBL2821 Locking Plug L22-30P

This Hubbell Wiring Device-Kellems locking plug is rated 30 amperes at 277/480 volts AC. The ribbed nylon housing provides a secure grip with impact and chemical resistance. A superior cord grip design protects terminations from excess strain during use. Clear, funnel-shaped wire entry allows for ease of termination in the field.

Industrial electricians and maintenance teams

The device suits three-phase 277/480V services where an L22-30P locking connection is specified. It is not suited for single-phase residential voltages or for circuits requiring a different NEMA locking configuration. Buyers needing a different amperage rating or voltage class should select the appropriate alternative.

30-ampere 277/480V AC rating

The 30 A, 277/480V AC rating is the single specification that determines whether this plug matches the installation. Verify the service voltage and breaker rating against these values before purchase. The integral dust shield protects the wiring chamber from contaminants during installation.

Questions about this item

What is the maximum continuous current the L22-30P locking plug is rated to carry?

The plug is rated for 30 A at 277/480 V AC, so sustained loads up to 30 amperes are within its design limit.

How much heat does the ribbed nylon housing dissipate when the plug runs at full load all day?

The nylon housing and superior cord grip are built for impact and chemical resistance; no specific temperature-rise figure is published for continuous 30 A operation.

What wire gauge and connector type must I already have to terminate this plug correctly?

The clear funnel-shaped wire entry accepts conductors suited for 30 A circuits; match the conductor size to your 277/480 V installation and follow local code.
