Watertight Locking Plug L5-20P

The Hubbell HBL26W47 is a straight-orientation locking plug rated for 20 A at 125 V AC. It uses a NEMA L5-20P configuration with three blades and two poles in a single-phase, polarised design. Industrial-grade construction suits demanding environments where reliable power connections are essential.

Sustained load behaviour

The housing combines thermoplastic elastomer and Valox for chemical and impact resistance. Watertight sealing maintains integrity during continuous operation in wet or harsh conditions. Screw-terminal wiring provides a secure connection that resists loosening under vibration or thermal cycling.

Build quality and connectors

Yellow housing ensures high visibility on job sites. Cable accommodation ranges from 0.375 in to 0.875 in diameter for flexible installation. The locking mechanism prevents accidental disconnection while the robust materials withstand repeated mating cycles in industrial settings.

Will this yellow L5-20P plug mate with my older 125 V twist-lock receptacles?
