This is a heavy-duty Hubbell back box for installing a shore power inlet on your boat or RV. It's made from cast aluminum with a corrosion-resistant gray finish, so it can handle the harsh marine or outdoor environment. The box has a 15-degree angled face, which is a common design to help keep water from dripping directly into the inlet. The hub size is 1-1/2 inch NPT (National Pipe Thread), which is the standard threading for the conduit or pipe that brings your power cable through. It's rated for 100-ampere receptacles and is designed for use with common AC voltages like 120/208V, 125/250V, and 277/480V. It has an IP67 rating, meaning it's dust-tight and can handle temporary immersion in water. This is the rugged enclosure you need before you even mount the actual power inlet receptacle. It's UL listed and CSA certified, so you know it meets safety standards. A crucial component for any proper marine or RV shore power setup.
