DEWENWILS 50 Amp RV Power Outlet Box NEMA 14-50R Galvanized Steel Weatherproof Lockable with Indicator

The DEWENWILS 50 Amp RV Power Electrical Outlet Box is a weather-resistant, lockable NEMA 14-50R receptacle assembly designed to provide safe, secure 50A shore power for RVs, trailers, and outdoor charging installations.

This compact, heavy-gauge outdoor outlet box combines an ETL-listed NEMA 14-50R receptacle with a galvanized-steel weatherproof enclosure and a swing cover. Built for exterior use, it accepts standard 50A RV power cords, gives a clear power-status indicator, and includes multiple knockout sizes and a lockable latch for vandal protection. The unit is intended for campers, travel trailers, utility hookups and any installation that requires a durable, code-friendly 50A power connection outdoors.

How does this outlet box keep outdoor power reliable?

The enclosure meets NEMA 3R weatherproof standards and uses rust-resistant galvanized steel to withstand rain, snow, and wind. A snug swing cover seals the receptacle when not in use, reducing moisture ingress and protecting internal wiring. The ETL listing of the box and UL listing of the 50A receptacle add verified safety compliance for electrical use.

• Galvanized steel housing resists corrosion and impact.
• NEMA-3R weatherproof rating for outdoor exposure.

What makes installation and wiring simpler for installers?

The box arrives with pre-punched knockouts on multiple sides so you can choose the routing that suits your setup—no extra drilling required. It includes three removable bushings for 1/2", 3/4", and 1" conduit or cable entries to match common wiring sizes. Inside, the larger cavity provides space for connections and mounting screws, and the swing cover can be fixed at a wide angle for easier access while wiring.

How does the unit improve security and convenience onsite?

An extended latch and blocking design prevent accidental or unauthorized opening, which helps protect the outlet from tampering or theft. The receptacle accepts a standard padlock for additional security at campsites, public hookups or unattended installations. A built-in power indicator LED lets you confirm power presence quickly without unplugging the cord.
