The 6 Best 50 Amp Inlet Boxes
Editor's Notes
February 16, 2021:
We replaced the Conntek 80SS2-CPBX with the Conntek GIB1450-025 – which comes conveniently bundled with a connection cable to hook up to your backup generator – and removed two models from Generac due to availability issues — namely the 6338 and 6344.
Our other new additions this time around were the LeisureRV Trailer Kit — which includes a twist-lock female connecter and an accompanying weatherproof boot, but oddly doesn’t include a male counterpart to plug into your RV generator or campsite supply; and the Rophor 3 Prong — which shot to the top of our list with its generous sizing and handy indicator LED.
Although this has already been stressed by this page’s last editor, I’ll reiterate: for your safety’s sake, make sure this device is installed by a reputable, licensed electrician. And, for your electrician’s sake, make sure you’re purchasing properly sized parts for your project. For smaller applications, we also maintain a separate list of 30-amp inlet boxes.

When selecting the right 50 amp inlet box, first and foremost, make sure it’s compatible with your generator. In addition, you want one that offers a straightforward setup, with multiple well-placed and large enough knockouts for the wires. (Be sure to have this electrical device installed by a licensed, professional electrician.) Since they’re usually placed outside, look for one that will withstand the elements. The Reliance Products PBN50 received top marks here as a safe model with a well-thought-out design to help protect it from rough weather. And it’s from a leading electrical device manufacturer, to boot. For a versatile choice that’s easy to install (and uninstall when the need arises), look to the ABN Marine Power Socket, which is made from heavy-duty materials, and as an added bonus, it's quite affordable. No matter which you go with, be sure to hook it up directly to a transfer switch, for safety’s sake. This will 1.) safeguard your appliances and electronics against harmful electrical overloads, and 2.) prevent back-filling of power lines, which could injure utility workers who are on nearby poles attempting to restore power to your area.
