RVGUARD RV Adapter Cord 50A to 15A Overload Protector — Resettable 15A Breaker & LED Indicator

The RVGUARD Overload Protector is a 50 Amp to 110 Volt adapter cord with a built-in 15A resettable circuit breaker that protects low-power appliances and battery charging when converting shore power.

When you need to plug a 15A household outlet into a 50A RV inlet—such as during long-term storage, maintenance, or when shore power options are limited—this adapter converts a standard 125V, 15A supply to a NEMA 14-50R receptacle while adding an overload trip and a power indicator. Rugged construction, ETL listing for the whole unit, and visible LED feedback make it a practical tool for RV owners who want safer, temporary power access without rewiring or complex equipment.

How does the built-in overload protection work?

The adapter contains a resettable circuit breaker rated to trip if current exceeds 15 amps, cutting power to prevent overheating or damage. Once you find and correct the cause of the overload, press the reset button to restore normal operation.

• 15A trip threshold prevents sustained overcurrent on the 125V side
• Manual reset button allows quick recovery after addressing the fault
• LED indicator confirms whether power is present before use
• Protects connected low-power devices and charging systems during temporary hookups

What electrical specs and safety certifications should I expect?

The cord is wired 10/3 gauge and is rated for 125 volts and up to 1875 watts when used on a 15A supply. RVGUARD supplies the adapter as an ETL-listed complete product, meaning the whole assembly (not just parts) was tested to North American safety standards.

• NEMA 5-15P (15A) male to NEMA 14-50R (50A) female
• 10/3 gauge copper wiring for reliable conductivity
• Rated 125V, 1875W maximum on the input side
• ETL listing for the finished product provides verified safety compliance

How durable and weather-resistant is the adapter for outdoor RV use?

The RVGUARD adapter uses 100% copper conductors encased in a heavy-duty, UV-resistant, flame-retardant PVC jacket to withstand outdoor exposure. Molded ends and robust strain relief reduce wear at connection points for longer service life.

• UV-resistant polyvinyl sleeve guards against sun damage and cracking
• Flame-retardant material improves safety near heat sources
• Molded connections minimize moisture intrusion and mechanical stress
• LED power light enclosed for visibility without compromising sealing

How will this adapter fit into my typical RV setup?

This adapter is intended for temporary conversion of a household 15A supply to a 50A RV inlet—ideal for charging batteries during storage, running low-draw appliances, or powering systems while the main shore power isn’t available. It is not designed to supply full 50A loads; use it only for low-power needs and always monitor amperage.

• Use for trickle charging, lights, fans, or small appliances
• Not suitable for running multiple high-draw devices simultaneously
• LED lets you confirm power before plugging in sensitive equipment
• Quick reset after overload eliminates need to replace fuses or cords

Who is this for: The RVGUARD Overload Protector 50A-to-110V adapter is built for RV owners, boaters, and storage facility operators who need a safe, temporary way to power or charge their vehicle from a standard household outlet. It's a practical accessory for anyone who wants clear power feedback, ETL-verified safety, and a resettable overload safeguard when full 50A shore power is unavailable.
