It is made of high-quality materials that are built to last. The box is weatherproof, so I can use it outdoors without worrying about damage from rain or other elements. Additionally, it is resistant to corrosion, making it a reliable option for long-term use.Overall, I highly recommend the Muelnmey 50Amp Power Outlet Box. It is a well-built, durable, and safe option for anyone in need of a 125/250Volt NEMA 14-50R outlet.

### ⭐⭐⭐⭐⭐ Works very well after installation
*by P***E on August 6, 2023*

I installed it in my garage for charging a Tesla Model 3; so far it works very well ... it looks great and I cannot feel any heat as I expect. Satisfied with the performance and appearance of the product.Two tricky issues:1. The wire openings do not fit US standard connectors ... the threads are thinner for US connectors. I use a 3/4" connector for the 1" opening instead of one of the two 3/4" openings on the box. Another option is to drill a 3/4" opening on a side of the box for the connector.2. The box needs to be installed on the wall ... need a few screws and drill some holes on back of the box. No instruction nor hardware is provided.The installation instruction is useless. One would think a company invested into developing and manufacturing a solid product should spend 30 minutes to write a useful instruction.
