ELEGRP 50 Amp NEMA 14-50R RV Outlet Box with Clear Lid — Weatherproof ETL-Listed, 6 AWG Ready

ELEGRP's 50 Amp NEMA 14-50R outdoor outlet box is a weatherproof, transparent-lid receptacle panel built to deliver reliable 125/250V service for RVs, travel trailers, motorhomes and electric vehicle temporary hookups.

This compact exterior receptacle combines a clear, NEMA 3R-rated cover with a rustproof polycarbonate body and a roomy interior designed for 6 AWG wiring. It was engineered to make campsite connections quick and safe while resisting outdoor wear — from UV exposure to freeze-thaw cycles. The unit carries ETL listing for outdoor use and includes multiple knockouts for flexible conduit routing, so electricians and DIY installers can complete hookups neatly and confidently.

How does the clear lid improve outdoor hookups?

The transparent cover lets you visually confirm plug engagement and inspect seals without lifting the lid, reducing exposure to weather and speeding routine checks. Its NEMA 3R rating keeps water spray and dust away from the receptacle while maintaining a modern exterior look.

• Clear polycarbonate lid for immediate visual inspection
• NEMA 3R protection against rain and falling debris
• Snap-fit hinge design for easy opening and secure closure

What makes the polycarbonate enclosure better than steel boxes?

High-strength polycarbonate provides impact resistance without the weight of metal and will not rust or dent like steel in coastal or humid environments. Its UV-stable formulation resists yellowing and cracking, preserving fit and finish over years of outdoor exposure.

• Rustproof, lightweight construction simplifies mounting
• Impact-resistant material for long-term durability
• UV-resistant shell prevents discoloration and brittleness

Is this outlet suitable for professional installation and heavy wiring?

Yes — the internal cavity is sized to accommodate 6 AWG conductors commonly used for 50 Amp circuits, with multiple 1" and 3/4" knockouts to accept conduit or flexible connectors. The spacious design reduces wire crowding and speeds a tidy, code-compliant hookup.

• Deep interior space for 6 AWG and terminals
• Multiple knockout sizes for installer flexibility
• Mounting bosses and pre-drilled points for secure attachment

What safety and outdoor-use certifications does it have?

ELEGRP's outlet box is ETL listed for verified performance and rated for outdoor environments, providing confidence in both electrical safety and environmental resistance. The combination of certification and robust materials makes it suitable for seasonal and year-round use.

• ETL listing for outdoor electrical equipment
• NEMA 3R cover rating for rain and dust protection
• Designed for temperature extremes and consistent power delivery
