The RVGUARD Overload Protector 30 Amp to 50 Amp RV Adapter Cord is a resettable, ETL-listed adapter that converts a campground 30A outlet to safely power 50A RV service while protecting against overcurrent.

When you pull into a campsite with only a 30 amp pedestal but your motorhome or trailer requires a 50 amp inlet, this adapter bridges the difference and adds an integrated overload protection feature. Built with 10/3 pure copper conductors and a molded, UV-resistant jacket, the cord is designed for outdoor RV use and gives a visual power indicator so you can confirm shore power at a glance.

How does the overload protection work and what should I expect when it trips?

The adapter includes a built-in circuit breaker that trips when current draw exceeds 30 amps. After identifying and correcting the cause of the overload, you press the reset button to restore power—no tools required. The resettable breaker prevents continuous overcurrent and simplifies recovery from nuisance faults.

  • Resets via front-mounted button after fault cleared
  • Trips automatically above 30A draw to protect wiring and devices
  • LED power indicator shows when pedestal power is present

Is this cord compatible with my RV and campground outlets?

This adapter converts a NEMA TT-30P (30A) campground plug to a NEMA 14-50R (50A) RV inlet, allowing most 50A RVs to draw shore power from a 30A pedestal. It’s rated for 125V and 3750W, and is intended specifically for RVs, campers, and travel trailers—not for charging electric vehicles or other non-RV uses.

  • 30A male (TT-30P) to 50A female (14-50R)
  • Electrical rating: 125V, 3750W, 30A maximum
  • 10/3 gauge pure copper conductors for reliable current flow

What durability and safety features are included?

The adapter is ETL tested as a complete product, not just component-certified, and is constructed with heavy-duty materials for outdoor use. A flame-retardant, UV-resistant polyvinyl sleeve protects the molded ends and conductors from weather and abrasion, while the pure copper wiring helps ensure consistent conductivity under load.

  • ETL-listed whole-product testing by Intertek
  • Molded connectors and 100% copper wiring for long life
  • UV-resistant, flame-retardant jacket for outdoor exposure

How do I install and troubleshoot the adapter on the road?

Installation is plug-and-play: insert the 30A male into the campground pedestal and connect the 50A female to your RV inlet. If power does not arrive, verify the pedestal is energized with the LED indicator, check your RV’s main breaker, and if the built-in breaker has tripped, correct the overload and press reset.

  • Plug 30A male to pedestal, connect 50A female to RV inlet
  • LED confirms shore power presence before connecting RV breakers
  • If tripped, find and fix the overload, then press reset button

Who is this for: RVGUARD’s 30A-to-50A Overload Protector is aimed at RV owners who frequently stay at campsites with limited pedestal options and want a safer, ETL-tested method to use 30A shore power with 50A RV systems. It’s ideal for travelers who value built-in overcurrent protection, clear power indication, and rugged, weather-ready construction. Note: not suitable for EV charging or non-RV electrical applications.
