EXCELFU 50 Amp 125/250 Volt NEMA 14-50R EV power outlet box is a weatherproof, lockable receptacle for Level 2 EV charging, RV use, and other high-load applications.

This heavy-duty outlet enclosure provides a dedicated 50A, 125/250V NEMA 14-50R receptacle built for outdoor and indoor mounting.

How does this outlet handle outdoor conditions?

The box uses a Type 3R-rated weatherproof enclosure and a hinged cover to shield the receptacle from precipitation and debris. Corrosion-resistant components and impact-resistant plastics help maintain reliability in varied climates without compromising safety.
