Hubbellock 20 A 125 V locking plug

The Hubbellock HBL23035B is a non-NEMA locking plug rated for 20 amps at 125 volts AC. It is built for heavy-duty power connections in harsh environments where safety and durability are critical. The plug suits industrial equipment, generators and temporary power distribution systems.

Super-tough nylon housing and cord grip

The one-piece nylon body resists high impact and heat while male contacts moulded into the nose prevent deformation. A mechanical cord grip clamps both the cable jacket and the conductors to deliver strain relief without separate hardware. Installation requires standard hand tools and basic wiring skill; the main error is under-tightening the terminal screws or the cord-grip clamp, which can lead to loose connections or cable pull-out.

Arc-protection shutter and 20 A headroom

Inside the mating connector a spring-loaded safety shutter covers the contacts until the plug is fully seated, reducing arc exposure during insertion and removal. The 20-ampere rating handles continuous loads up to that level on 125-volt circuits. It is not suited for higher-voltage systems, three-phase supplies or applications demanding NEMA-standard pin configurations.

Questions about this item

How can I verify the HBL23035B locking plug is working correctly after wiring it to a 20 A 125 V AC circuit?

After installation, confirm the nylon housing sits flush with the matching receptacle and the cord grip holds the cable firmly; the spring-loaded safety shutter inside the mating connector should engage automatically when the plug is inserted, providing arc protection and a positive mechanical lock.

What components are included with the Hubbellock HBL23035B plug and what must be sourced separately?

The package contains the locking plug body with molded male contacts, super-tough nylon housing, and integrated mechanical cord grip; you must supply the appropriate cable and a compatible Hubbellock connector body or receptacle to complete the connection.

Which Hubbellock plug version should I select for a 20 A 125 V AC non-NEMA application?

Choose the HBL23035B model; it is rated 20 A at 125 V AC, uses the non-NEMA Hubbellock locking interface, and features the thermoplastic interior and spring-loaded safety shutter designed for heavy-duty environments.
