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.

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.
