Nilight 50Amp RV EV Power Outlet Box NEMA 14-50R 125/250V Weatherproof Metal Enclosure ETL Listed

The Nilight 50AMP RV EV Power Outlet Box is a weatherproof, ETL-listed NEMA 14-50R enclosure designed to supply 125/250V, 50 amp service for RVs, EV charging, generators and heavy-duty equipment.

This heavy-duty outdoor/indoor metal outlet box combines safe, code-compatible connections with user-focused refinements to simplify installation and everyday use. Built with a powder-coated shell, improved lid closure, gasketed knockout panel, and pre-drilled wire entry points, it’s intended to protect high‑current wiring from the elements while giving installers plenty of room for large gauge conductors.

How does this outlet box support EV charging and RV power safely?

The Nilight box houses a NEMA 14-50R receptacle rated for 50 amps at 125/250V, making it suitable for common RV shore power and many EV charging setups. ETL listing confirms it meets nationally recognized safety standards for electrical enclosures. The weatherproof design and internal space help keep connections secure and accessible.

• Includes NEMA 14-50R receptacle rated 50AMP 125/250V for RVs, EVs, generators.
• ETL tested to recognized safety standards comparable to UL.
• Rubber gasket and splash-resistant construction protect internal wiring.

What installation features make it easier for electricians and DIYers?

Nilight upgraded the enclosure to address a common problem—closure of the lid—by adding extra internal clearance so the door closes and locks without pinching cables. The box comes with four pre-drilled knockout points so you can route wires from multiple directions without additional drilling. Three different-size gaskets are included for a cleaner, sealed fit around various cable diameters.

• Pre-drilled wire entry points reduce time and effort during mounting.
• Three multi-size gaskets (1", 1/2", 3/4") for different cable sizes.
• Generous internal space to accommodate large gauge conductors and connectors.

Is the enclosure durable enough for outdoor, garage, or marine use?

Constructed from heavy-gauge metal with a protective powder coating, the Nilight outlet box resists corrosion and everyday wear. The knockout panel includes a rubber gasket to boost impact resistance and keep moisture out of the wiring area. While it’s designed to be splash- and weather-resistant, proper installation and sealing remain important for long life in exposed locations.

• Powder-coated metal shell for corrosion resistance and long-term durability.
• Rubber gasket under the knockout panel improves waterproofing and impact resistance.
• Suitable for garage, backyard, campground pedestal, or sheltered outdoor locations.
