WELLUCK RV Power Outlet Box 50A NEMA 14-50R — Lockable Weatherproof Enclosure with Extra Depth

The WELLUCK 50A RV Power Outlet Box is a lockable, weatherproof NEMA 14-50R receptacle that delivers 125/250V, safe temporary hookup for RVs, travel trailers, and generators.

Engineered for mobile living, construction sites, and outdoor power needs, this enclosed WELLUCK outlet combines UL-certified safety with a rugged, corrosion-resistant cabinet. It accepts standard 50A NEMA 14-50P cords and includes a type 3R rainproof cover, extra interior depth for bulky plug handles, and a new padlock-ready design to deter theft. The box's three electrical knockouts simplify wiring while the galvanized-steel housing resists the elements for long-term use.

How does this outlet keep power connections safe outdoors?

The WELLUCK enclosure uses a type 3R rainproof cover and a double-coated galvanized steel shell to protect wiring and the receptacle from moisture and corrosion. It is UL-certified, meaning it meets recognized electrical safety standards. A padlockable swing-up door adds theft and tamper protection while still allowing the cord to remain plugged in.

• Type 3R rainproof cover shields from rain and snow
• Double-coated galvanized steel resists rust and impacts
• Padlock feature and swing-up door for theft prevention
• UL certification for recognized safety compliance

Will it fit large 50A RV plugs and bulky cord handles?

Yes. WELLUCK redesigned the interior depth so larger pull-handle cords can be plugged in without forcing or bending. The extra space accommodates special-shaped plugs while still allowing the cover to close and lock for security. This makes it convenient at campgrounds and temporary hookup locations.

• Increased internal depth for bulky handles
• Works with standard 50A NEMA 14-50P RV cords
• Cover closes while cord is connected

How straightforward is installation and wiring?

Installation is designed to be user-friendly: three electrical knockouts accept common conduit sizes so you can route power without complicated modifications. Simply use a step drill or hole cutter to open the desired knockout, secure conduit, and wire according to local electrical codes. The layout leaves enough room for terminations and strain reliefs.
