Tellegloww L14-30P to SS2-50R 20FT Generator-to-RV Adapter Cord — 30A 10AWG Locking, Weather-Resistant

Tellegloww's 20-foot adapter cord converts a 4-prong NEMA L14-30P generator outlet to a locking SS2-50R 50A inlet, delivering a weather-resistant, heavy-duty link for RVs, boats, and transfer panels.

If you need a reliable way to route power from a 30A generator to a 50A inlet on an RV, shore power pedestal, or home transfer box, this adapter was engineered for that exact task. The cord combines a locking L14-30P male plug with an SS2-50R locking female inlet on a 20-foot 10AWG cable, built to resist outdoor conditions and provide a secure connection for temporary power setups.

How does this adapter let me use a 30A generator with a 50A inlet?

The Tellegloww adapter converts the generator's L14-30P 4-prong locking plug to a standard SS2-50R 50A locking receptacle so your 50A inlet or shore power cord can plug in without modification. It routes 125/250V circuits through heavy-gauge copper conductors while preventing accidental disconnection thanks to the female locking ring.

• 20-foot length gives extra reach between generator and inlet.
• 10 AWG, 4-conductor copper wiring carries the load safely.
• Locking SS2-50R prevents accidental unplugging under tension.
• Compatible with both 125V and 250V systems up to 30A continuous.

Is the cable durable enough for outdoor, marine, or RV use?

This adapter is made for repeated outdoor service: molded plugs and a water-resistant jacket defend against moisture and abrasion, while flame-retardant and UV-stable materials reduce weathering. The copper conductors are coated to slow oxidation, and the assembly is built to withstand rough handling common around campsites and docks.

• Heavy-duty molded L14-30P and SS2-50R connectors for impact resistance.
• UV-resistant outer jacket for sun-exposed environments.
• Water-resistant construction for splashes and damp conditions.
• Flame-retardant materials increase safety near heat sources.

What safety features should I expect when using this adapter?

The adapter prioritizes secure electrical contact and physical retention: the female SS2-50R uses a locking ring to maintain engagement, and the L14-30P locks into standard generator outlets. Using the proper gauge wiring and molded strain-relief reduces heat buildup and wear, helping preserve safe operation when delivering temporary power.

• Locking SS2-50R ring holds shore power cord in place under tension.
• Molded strain reliefs reduce conductor stress at each end.
• 10AWG copper conductors limit voltage drop over the 20ft run.
• Rated for 125/250V service with appropriate circuit protection upstream.

Will this adapter work with my RV, boat, or whole-house transfer switch?

Yes—if your shore inlet or distribution center accepts NEMA SS2-50P/SS2-50R 50A connections and your generator provides an L14-30P outlet, this adapter bridges the two. It is intended for temporary power distribution and should be used in line with local codes and your equipment's amperage limits.

• Connects 30A generator L14-30P to 50A SS2-50R inlet on RVs and boats.
• Works with transfer switches and inlet boxes that accept SS2-50P cords.
• Designed for temporary or emergency power, not permanent wiring.
• Always verify upstream circuit protection and compatibility before use.

Who is this for? This Tellegloww adapter is aimed at RV owners, boaters, weekend campers, and homeowners who need a dependable, portable way to link a 30A generator to 50A inlets or shore power pedestals. It’s particularly useful during outages, at remote campsites, or when shore power types differ; professional installers and DIYers who follow local electrical codes will find it a practical addition to their power-connection toolkit.
