Built for the Toughest Marine Conditions

Engineered specifically for marine applications, this Hubbell twist-lock receptacle delivers unwavering performance where moisture, salt air, and constant vibrations are part of daily life. Boat owners, dock operators, and marina managers rely on its robust design to power high-demand equipment without the worry of loose connections or corrosion buildup. Unlike standard outlets, the twist-lock mechanism secures plugs firmly, preventing accidental disconnections that could lead to downtime or hazards on the water.

Key Features That Stand Out

• Heavy-Duty Power Handling: Rated for 50A at 125/250V, it supports everything from boat lifts and pumps to welding gear and large appliances, ensuring reliable energy delivery under load.
• Corrosion-Resistant Construction: Thermoplastic composite body paired with galvanized components shrugs off saltwater exposure, making it ideal for docks, piers, and vessel installations.
• Secure Twist-Lock Design: The iconic Hubbell Twist-Lock® system rotates to lock plugs in place, providing superior retention even in rough seas or high winds.
• Screw Terminal Connections: Facilitate quick, secure wiring with stranded or solid conductors, minimizing installation time and enhancing long-term reliability.
• Visible Yellow Housing: Enhances safety by making the outlet easy to spot in low-light conditions or cluttered work areas.

Why This Receptacle Excels in Real-World Marine Use

In marine settings, standard electrical devices often fail due to environmental stress. This model changes that with its 3-pole, 4-wire grounding configuration, which meets stringent safety standards for grounding critical equipment. It's perfect for shore power setups, where boats plug in for extended stays, or for powering dockside tools that demand high amperage. The IP20 rating suits indoor dry locations or protected outdoor spots, but its marine-grade build extends usability to sheltered marine environments.

Users report fewer callbacks for service compared to generic alternatives, thanks to the durable materials that resist cracking, fading, or seizing over seasons of exposure. Whether retrofitting an older dock or outfitting a new build, it integrates seamlessly with screw mounting hardware for straightforward installs on wood, metal, or composite surfaces.

Installation and Maintenance Tips

Getting this receptacle up and running is straightforward for electricians familiar with marine wiring. Strip conductors to the recommended length, secure them in the screw terminals with proper torque, and mount using the included hardware. Always verify grounding integrity with a tester before energizing. For longevity, inspect connections annually for corrosion—though its galvanized protection minimizes this need—and clean with a mild, non-abrasive solution if needed. Pair it with matching plugs for a complete, code-compliant system.

Pro Tip:

In high-vibration areas like engine compartments, add lock washers to mounting screws for extra stability.
