Hubbell HBL504SS SS Inlet 50A 125/250V Product Description

Equip your vessel with unmatched reliability using this rugged stainless steel shore power inlet designed for the harshest marine environments. Crafted for boaters who demand durability without compromise, it delivers a secure 50A connection at 125/250V, ensuring your onboard systems stay powered seamlessly during extended dockside stays or quick recharges.

Unlike flimsy alternatives that corrode under constant exposure to saltwater spray and UV rays, this inlet's premium stainless steel construction laughs off the elements. The gasketed, self-closing lid snaps shut effortlessly, creating a barrier against rain, waves, and debris when you're not plugged in. Once connected, it seals watertight, giving you peace of mind whether you're prepping for a weekend cruise or weathering an unexpected squall.

Standout Features for Serious Boaters

  • Heavy-Duty Stainless Steel Build: Resists rust and pitting far better than standard materials, ideal for coastal or offshore use where corrosion is a constant threat.
  • Self-Closing, Gasketed Cover: Automatically protects internal contacts from moisture and contaminants, extending service life in wet conditions.
  • IP56 Rated Protection: Shields against powerful water jets and dust ingress, meeting rigorous marine standards for safety and performance.
  • Precise Mounting Design: Holes spaced 2-3/8 inches (60.3 mm) on centers with a 2.171-inch (55.1 mm) rear diameter for straightforward flush or surface installs on hulls or bulkheads.
  • Complete Kit Included: Comes ready to mount with screws and gasket, minimizing downtime during setup.

Engineered for Marine Endurance

In the world of boating, power failures aren't just inconvenient—they can be dangerous. This inlet stands out by prioritizing long-term resilience. Stainless steel isn't just a buzzword here; it's forged to withstand galvanic corrosion from dissimilar metals in bilge water or dockside fittings. Boaters report years of trouble-free operation even after thousands of connect-disconnect cycles, thanks to the smooth, low-friction contacts that prevent arcing and overheating.

Picture this: You're hauling gear aboard after a fishing trip, waves lapping the hull, and you plug in without a second thought. No fumbling with stiff covers or worrying about water intrusion—the self-closing mechanism handles it, while the IP56 rating ensures it performs in downpours or high-pressure washdowns.

Simple Installation and Everyday Use

Getting it up and running is straightforward for DIY-savvy owners or pros. Prep your mounting surface, align the holes, secure with provided screws, and seal the gasket for a flawless fit. No special tools needed beyond basics, and the compact rear profile fits tight spaces on most mid-size to large boats.

Pro Tips for Optimal Setup:

  1. Clean and dry the mounting area thoroughly to maximize gasket adhesion.
  2. Use marine-grade sealant around the edges for extra waterproofing in splash zones.
  3. Route wiring through strain relief to prevent chafing from boat vibrations.
  4. Test connections with a multimeter before full power-up to confirm continuity.

Once installed, daily use is intuitive: Lift the cover, align your shore cord, and lock in. Disconnect by twisting free—quick, secure, and no exposed live parts.

Maintenance Made Effortless

Keep it performing like new with minimal effort. Periodically inspect the gasket for wear and replace if cracked. Wipe down the stainless surface with mild soap and a soft cloth to remove salt buildup—avoid abrasives that could scratch the finish. Annually, check contacts for pitting and apply dielectric grease if needed to fend off oxidation. This proactive approach ensures decades of dependable service, outlasting cheaper imports that fail prematurely.

Why Boaters Trust This Inlet

From weekend warriors to liveaboard captains, those in the know choose stainless for its no-nonsense toughness. It handles the rigors of frequent docking at marinas, fuel docks, or private slips without the headaches of frequent replacements. Paired with quality shore cords, it supports high-draw appliances like air conditioners, chargers, and cooking gear, all while maintaining cool operation under load.

Elevate your boat's electrical backbone—reliable power means more time enjoying the water, less time troubleshooting.
