Tellegloww 25ft L14-30P to SS2-50R Adapter Cord – 30A 4-Prong Locking RV/Marine Power, Weather-Resistant

The Tellegloww 25ft adapter cord converts a 30A L14-30P generator output into a secure 50A SS2-50R shore power inlet for RVs and boats, delivering a weather-resistant, locking connection for 125/250V use.

When you need to link a 30-amp generator to a 50-amp RV inlet or marine shore power socket, the right adapter must be safe, durable, and simple to use. Tellegloww engineered this 25-foot NEMA L14-30P to SS2-50R cable to provide a reliable bridge between generator power and 50A shore/RV systems, with a locking ring on the female end, heavy-gauge copper conductors and a rugged outdoor jacket built to handle the elements.

How does this adapter let a 30A generator feed a 50A RV or marine inlet?

The adapter maps the generator's four-prong L14-30P output into the SS2-50R female inlet so essential circuits can receive power while clearly limiting the amp draw to the generator's 30A capacity. It does not increase your generator's output; instead it routes available power safely into the RV or shore system through properly matched conductors and connectors.

• 4-prong L14-30P male plug fits standard 30A generator outlets
• SS2-50R locking female accepts 50A shore power cords
• 10 AWG/4C copper wiring manages 30 amps without overheating
• Supports both 125V and 250V configurations in typical transfer setups

Is this cord durable and safe for outdoor, marine, or campsite use?

Yes — the Tellegloww adapter uses flame-retardant, UV-resistant molded plugs and a water-resistant jacket to resist sun, moisture, and abrasion in outdoor environments. The locking ring on the SS2-50R end secures the connection under vibration or movement, while the copper conductors are coated to reduce oxidation and maintain conductivity over time.

• Heavy-duty molded connectors with flame-retardant construction
• UV-resistant, weatherproof outer jacket for extended outdoor life
• Locking female ring prevents accidental disconnects in rough conditions
• Oxidation-resistant copper wiring for consistent power transfer

Will this adapter work with my transfer switch, inlet box, or shore power setup?

The adapter was designed for universal compatibility with common 50A RV and marine inlet arrangements and many household inlet boxes that accept SS2-50R-type connections. It provides a straightforward physical interface between a 30A generator and 50A inlets or distribution centers, but always consult your equipment manuals or an electrician to confirm safe use in transfer switch or permanent inlet installations.

• Compatible with NEMA SS2-50P shore power cords and inlets
• Connects to L14-30 outlets on generators and portable power units
• Works with RV/marine distribution centers and many inlet boxes
• Best used for temporary power transfer; check transfer switch requirements

How do I use and maintain the Tellegloww adapter for reliable performance?

Connect the L14-30P male to your generator and securely fasten the SS2-50R female to your RV or shore cord, engaging the locking ring. After use, inspect plugs and jacket for damage, keep terminals dry, and store the cord coiled in a dry place to prolong service life.

• Always match generator output and load demand to avoid overload
• Engage the SS2-50R locking ring for a secure, watertight fit
• Rinse salt spray from marine use and dry before storage
• Check for cuts, abrasions, or loose contacts before each use

Who is this for: The Tellegloww 25ft L14-30P to SS2-50R adapter suits RV owners, boaters, and anyone using a 30A portable generator to power 50A shore or inlet systems temporarily. It’s made for campers, marine enthusiasts, and homeowners needing a rugged, locking generator-to-inlet solution that prioritizes weather resistance and secure connections without modifying electrical systems.
