20 A L5-20 Locking Plug

The Hubbell HBL23CM11 is a NEMA L5-20P locking plug rated for 125 V AC at 20 A. Its ribbed nylon housing provides grip, impact resistance and chemical resistance for industrial and marine use. Nickel-plated brass blades ensure reliable conductivity. The plug accepts cord diameters from .360 to .930 inches and wire sizes from #16 AWG to #8 AWG stranded copper.

Suited for 125 V 20 A twist-lock connections

This plug suits installers who need a secure, grounded connection on 125 V AC circuits up to 20 A in harsh environments. The integral dust shield helps keep contaminants out of the wiring chamber. Builders who require a different NEMA configuration, a higher voltage rating or a non-locking straight-blade plug should look at other products.

NEMA L5-20P configuration decides fit

The single specification that determines compatibility is the NEMA L5-20P configuration for single-phase, grounded 125 V AC at 20 A. Only receptacles matching this exact NEMA code will accept the plug. Verify the mating receptacle before purchase.

Questions about this item

What cord diameter do I need so the HBL23CM11 locking plug grips it securely?

The plug accepts cables from .360 to .930 inches; choose a cord within that range for a firm grip.

Will this L5-20P plug mate with an existing L5-20 receptacle on my boat?

Yes, the NEMA L5-20P configuration matches standard L5-20 receptacles for 125 V AC single-phase grounded circuits.

How can I confirm the nickel-plated brass blades are making solid contact after wiring?

Verify 125 V AC at the receptacle with a multimeter and check that the locking collar engages fully without overheating under a 20 A load.
