WEBANG RM50DFPB 50-Amp RV Power Outlet Box, Lockable, Weatherproof NEMA 14-50R

A permanent RV hook-up calls for a different setup than a portable connection. The WEBANG RM50DFPB provides a fixed NEMA 14-50R receptacle in an enclosed box for an RV, camper or travel trailer parking area.

Its lockable, outdoor-rated enclosure keeps the receptacle covered between uses. The box is also listed for indoor installation, making it suitable for a planned connection point near a main breaker panel or parking space.

With a 50-amp rating and 125/250 V receptacle, it is designed for RV power connections and can also serve an appropriately configured EV charging setup.

Why it makes sense

The enclosed design brings the receptacle and its connection point together in one unit, rather than leaving an outlet exposed at the installation location. A lock helps restrict access when the outlet is not in use, while the weatherproof construction supports outdoor placement. The product is ETL listed and uses a NEMA 14-50R receptacle rated for 125/250 V and 50 amps.

Clearance is a practical advantage when a cord is plugged in: the box is designed to close with a 30A RV cord connected, including cords with a large handle or a stiff, heavy-duty wire. Its lid can also stay raised while the box is being worked on. That makes the enclosure useful for an RV parking area where the connection needs to remain covered when in use, yet accessible during installation or service.

Buyers often describe the outlet as solid and say it performs its intended function. Feedback on installation and wire fit is mixed, so matching the wiring and connector requirements to the planned installation is an important part of selecting and setting up a hardwired outlet.

What to know

This is a hardwired, single-outlet panel with a NEMA 14-50R receptacle. The stated rating is 50 A at 125/250 V. It is intended for use with an RV, camper or motorhome, and the product information also describes use with an electric vehicle or generator when the overall setup is suitable. The receptacle type and electrical requirements should match the equipment and circuit being connected.

For installation, the product information recommends routing wiring through the existing opening at the top. Knockouts are also provided on the bottom and sides, opening one may require tools such as a knockout punch set, hammer and screwdriver. Plan the wiring route and mounting position before fitting the box, and have hardwired electrical work completed safely by a qualified professional.

How to use it

Choose an indoor or outdoor location suited to the RV’s parking position and the route from the electrical supply. Mount and wire the enclosure, then connect the compatible RV cord to the NEMA 14-50R receptacle. The box’s available space is designed to let the lid close around a connected 30A RV cord, helping keep the outlet enclosed during use. Keep the lid raised while working inside the box, and use the lock when the outlet is not in use.

Final verdict

For RV owners planning a fixed power point, the WEBANG RM50DFPB combines a lockable enclosure, outdoor-rated construction and a 50-amp NEMA 14-50R receptacle. Its cord clearance is a useful detail for a parking-space hook-up, while the hardwired design suits a permanent installation planned around the electrical supply and the vehicle’s connection needs.
