Review on 🔌 High-Quality 50 Amp RV Power Outlet Box | Weatherproof Enclosed NEMA 14-50R Receptacle Panel - Ideal for RVs, Trailers, Motorhomes, Electric Cars, and Generators by Sandro Pierce

I bought two of these for a permanent RV site. I will return both. The box is easy to install and deep enough for large van cables, but the connector itself is flawed. As you can see in the picture the screw goes through the center of the hole where your wire goes in. For my application I used #6 wire from the panel due to the length of the wire. We tried twisting the wires in a "Y" shape to "disconnect" the screw, but because the screw heads are so small you can't really tighten the wire. The second photo shows small screw heads. They are about the size of a Phillips #1 head. I would not recommend this product.
