WILAWELS 50A NEMA 14-50R RV Power Outlet Box — Lockable Weatherproof Galvanized Steel Enclosure, ETL Listed

The WILAWELS 50 Amp NEMA 14-50R RV power outlet box is a weatherproof, lockable outdoor electrical enclosure that supplies 125/250V power to campers, trailers, and outdoor equipment with added safety and corrosion resistance.

This rugged receptacle panel is built for seasonal living and daily use where a dependable, high-amperage connection is required. Constructed from galvanized steel with a durable protective coating and ETL certification, the unit protects the outlet and internal wiring from rain, dust, and accidental contact while providing a clean, installer-friendly layout. It’s designed to be mounted on walls or pedestals at campsites, garages, yards, or RV parks and works with standard NEMA 14-50R plugs used by many RVs and electric devices.

How does this outlet box withstand outdoor conditions?

The enclosure uses a 3R-rated shell made from high-grade galvanized steel and a double protective finish to resist rust and corrosion. The lid overlaps the housing to keep water out, and the sealed design reduces dust ingress so internal components stay dry and functional over time.

• Galvanized steel construction with dual-coating for long-term rust resistance
• 3R rating for outdoor weather protection against rain and snow
• Overlapping lid and gasketed openings to limit dust and moisture entry

What safety features protect people and property?

Safety-focused details reduce accidental exposure and unauthorized use. The lid is lockable and designed to auto-secure when closed; a press-down mechanism prevents children or bystanders from easily opening the cover. A visible power indicator confirms when the outlet is energized so users know when it’s live.

• Lockable lid with automatic locking action for tamper resistance
• Press-down opening mechanism to prevent accidental access
• Integrated power indicator light to show when the circuit is active

How straightforward is installation and wiring?

The box includes factory-cut wire pass-throughs on the back and bottom, removing the need to drill additional holes for cable entry. Inside, a raised shell provides extra clearance for thicker cables and connectors, and the mounting pattern fits common outdoor pedestal or wall installations.

• Pre-punched bottom and rear wire access points for quick hookup
• Generous internal space to accommodate various wire sizes and connectors
• Standard mounting footprint compatible with common installation setups

What certifications and compatibility should I expect?

This receptacle panel is ETL listed, indicating it meets recognized electrical safety standards. The NEMA 14-50R configuration supplies 125/250V at up to 50A, compatible with many RVs, mobile service units, and high-power outdoor appliances that use this widely adopted connector.

• ETL certification for verified electrical safety and compliance
• NEMA 14-50R configuration delivering up to 50 amps at 125/250V
• Works with standard 14-50 plugs used by RVs, trailers, and EV chargers requiring a similar receptacle
