Tellegloww 3FT L14-30P to SS2-50R Adapter Cord — 30A 4-Prong Locking, 125/250V UV-Resistant for RV & Marine Temporary Power

Tellegloww's 3ft NEMA L14-30P to SS2-50R adapter cord converts a 4-prong locking generator outlet into a secure 50A marine/RV inlet for reliable temporary power transfer.

If you need a short, dependable cable to link a 30A L14-30P generator outlet to a 50A SS2-50R shore or RV inlet, this heavy-duty Tellegloww adapter does that job while resisting weather and physical wear. The cord pairs a locking L14-30P male plug with a SS2-50R locking female connector and is built for both 125V and 250V applications. It gives a compact, portable solution for powering an RV, boat, or home transfer switch during outages, shore connections, or generator use.

How does this adapter let a 30A generator serve a 50A inlet?

The adapter routes the generator's four-wire L14-30P connection into a SS2-50R 50A shore power inlet, using heavy-gauge copper conductors and proper grounding to maintain safe transfer. It is intended for temporary power distribution and matches voltage configurations for 125/250V systems.

• 4-prong locking L14-30P male to SS2-50R 50A female.
• Supports 125V and 250V configurations.
• 10 AWG, 4-conductor copper wiring for reliable current flow.
• Designed for temporary generator-to-inlet hookups, not permanent rewiring.

Will it hold up to outdoor and marine use?

Yes — the adapter is made with flame-retardant and UV-resistant molded plugs plus a water-resistant jacket to resist sun, spray, and light moisture. The locking female connector keeps the cord engaged under movement, making it suitable for RV, marine, and outdoor generator setups.

• UV-resistant housing prevents sun damage.
• Flame-retardant plug material improves safety near heat sources.
• Locking ring on SS2-50R secures the connection against vibration.
• Oxidation-resistant copper conductors extend service life.

Is this safe for use with my transfer switch or shore power inlet?

The Tellegloww adapter is engineered to create secure, low-resistance connections between compatible generator outlets and 50A inlets. Use it for temporary power solutions and follow local electrical codes; it should not replace dedicated hardwired transfer equipment or be used as a permanent installation.

• Provides a locking, secure mate to SS2-50 inlet boxes.
• Properly configured for 30A generator output into 50A inputs when used as intended.
• Recommended for temporary, supervised power transfer events.
• Follow manufacturer and code instructions for safe operation.

How compact and portable is this adapter for travel and storage?

At 3 feet long, the adapter is intentionally short for tidy storage and minimal cable clutter during use. Its compact footprint makes it straightforward to stow in an RV bay or boat locker while still providing the reach needed between a generator and an inlet or power distribution point.

• 3-foot length is easy to coil and store.
• Rigid molded plugs resist deformation during transport.
• Light enough to carry with other generator or shore-power gear.
• Short run reduces voltage drop for temporary connections.

Who this is for: Owners of portable generators, RVers, and boaters who need a short, rugged adapter to connect a 30A L14-30P generator outlet to a 50A SS2-50R inlet will find this Tellegloww cord practical. It's aimed at users seeking weather-resistant construction, a locking 50A connection, and compact portability for temporary power transfer situations. Not intended as a permanent replacement for fixed wiring or dedicated transfer equipment; always confirm compatibility with your generator, inlet, and local codes before use.
