30A to 50A RV Adapter Cord with Circuit Breaker and LED Indicator

Need to plug a 50 amp RV into a 30 amp campground pedestal? This 30A to 50A RV adapter cord gives you a cleaner, safer way to connect when the site only has a TT-30 outlet available.

The built-in circuit breaker adds a helpful layer of overload protection, while the LED power indicator lets you confirm power at a glance before you settle in for the night.

Why RVers keep this in the power bin

• 30A male to 50A female connection: NEMA TT-30P plug to NEMA 14-50R receptacle for compatible RV shore-power hookups.
• Built-in circuit breaker: designed to trip when the adapter is overloaded, helping you catch a problem before it turns into a bigger headache.
• LED power indicator: a quick visual check that the pedestal is supplying power.
• 18 inch dogbone design: flexible enough to reduce strain at the pedestal compared with stiff block-style adapters.
• Outdoor-ready build: heavy-duty STW jacket, copper conductors, and molded handles for campground use.

Protection-first setup note

An adapter helps you make the physical connection, but it does not turn a bad pedestal into a safe one. For the cleanest setup path, check campground power with the right surge protector first, then use the adapter only when the amperage connection matches your RV plan.

Best for

• 50 amp RVs parked at campsites with only a 30 amp outlet available.
• Keeping a backup adapter on board so a bad or missing 50 amp receptacle does not ruin the setup.
• Campers who want a clear power indicator and resettable breaker in the adapter itself.

Important compatibility note

This adapter does not increase available campground power. A 50 amp RV connected to a 30 amp pedestal is still limited by the 30 amp supply, so high-draw appliances should be managed carefully. This adapter is intended for RV use and is not intended for EV charging.
