Hubbell HBL31CM28 Adapter 30A Female To 15A Male Product Description
Boat owners and marine enthusiasts often face the challenge of mismatched shore power connections at docks or marinas. The Hubbell HBL31CM28 adapter bridges that gap effortlessly, allowing your 30A 125V twist-lock plug to connect securely to a standard 15A or 20A 125V straight blade receptacle. Built for the demanding marine environment, this adapter ensures reliable power delivery without the hassle of hunting for compatible outlets.
Robust Design for Marine Reliability
Crafted with Hubbell's signature durability, the HBL31CM28 features corrosion-resistant materials that stand up to saltwater spray, humidity, and constant exposure to the elements. Its twist-lock female end provides a secure, vibration-proof connection, while the straight male blade end fits snugly into everyday receptacles. Rated for IP20 suitability, it offers solid protection against larger debris, making it ideal for above-deck use on recreational boats, yachts, or fishing vessels.
- 30A 125V female twist-lock (NEMA L5-30R) to 15A/20A 125V male straight blade (NEMA 5-15P)
- Heavy-duty construction with reinforced housings to prevent cracking under stress
- Precise engineering minimizes power loss and heat buildup during extended use
- Compact and lightweight for easy stowing in tight bilge spaces or onboard lockers
Unlock Seamless Shore Power Access
Imagine pulling into a slip with limited power options—no more borrowing extension cords or settling for partial power. This adapter lets you tap into standard outlets to run essentials like lights, fridge, or charging stations safely. It's a game-changer for weekend warriors docking at public ramps or older marinas where 30A twist-lock pedestals are scarce. By stepping down the amperage responsibly, it protects your boat's electrical system from overloads, giving you peace of mind on every outing.
Users rave about its plug-and-play simplicity, turning frustrating setups into quick connections. Whether you're powering up for a family cruise or an overnight fishing trip, it delivers consistent performance that keeps your adventure uninterrupted.
Simple Setup for On-Water Confidence
Connecting is straightforward: Align the twist-lock prongs with your shore power cord's male end, twist to lock, then insert the straight blade into the receptacle. Always verify the outlet's capacity first to avoid tripping breakers. For best results, use in dry conditions and inspect for wear before each trip. Pair it with a surge protector for added defense against voltage spikes common in marina power supplies.
Pro Tips for Longevity
- Rinse with fresh water after saltwater exposure to prevent corrosion
- Store in a dry bag to shield from moisture
- Avoid overloading by monitoring total draw from connected appliances
- Check connections monthly for secure fit and insulation integrity
Versatile Fit for Diverse Setups
This adapter shines in compatibility, working seamlessly with most 30A marine shore cords and standard household-style outlets. It's perfect for RVers adapting to campground pedestals too. Note that while rated for 125V, always match your boat's requirements—it's not suited for 240V systems or higher amps. Hubbell's precise molding ensures a wobble-free fit, reducing arcing risks that plague cheaper alternatives.
