Industrial Marine Locking Plug

The Hubbell HBL26CM21 is a NEMA L6-30P locking plug rated for 30 A at 250 V AC single-phase. It is built for industrial and marine environments where vibration, moisture and chemical exposure demand a secure, polarised and grounded connection. The ribbed yellow nylon housing provides grip and is rated impact resistant and chemical resistant.

30 Amp Capacity and Cord Range

The device accepts portable cords from 0.360" to 0.930" diameter covering 16 AWG to 8 AWG conductors. An integral dust shield protects the wiring chamber from contaminants while a cord grip manages strain on the screw-terminal connections. Continuous operating temperature spans -40°C to +75°C, so the plug retains performance in extreme cold and heat without derating.

Upgrade From Non-Locking or Lower-Rated Plugs

This unit replaces standard straight-blade plugs that can loosen under vibration or lack the environmental sealing required on docks, generators or heavy equipment. The jump is worth it when a UL 498 listed, CSA C22.2 No.42 certified, W-C-596 compliant device is specified and the application demands a locking interface with nickel-plated brass blades for corrosion resistance.

Questions about this item

Will the HBL26CM21 30 A 250 V locking plug mate with my existing L6-30R receptacle?

Yes, the NEMA L6-30P configuration is polarised and grounded to match any standard L6-30R outlet.

How can I verify the plug is seated and making proper contact after wiring?

The twist-lock action engages with a positive click and the blades cannot rotate further when fully locked.

Does the package include a cord or only the plug body?

Only the plug body is supplied; you must provide a portable cord between 0.360" and 0.930" diameter (16 AWG to 8 AWG).
