The XP50PB Metallic Inlet Box is a high-capacity, heavy-duty inlet engineered for whole-home generator backup systems. It supports up to 12,500 running watts and handles 50 amps at 120/240 volts, making it perfect for safely channeling power from a portable generator into your home's electrical system. Built for outdoor durability, it features a sturdy NEMA 3R metallic enclosure designed to withstand weather and environmental exposure. Installation is made easy with four 1/2 in. and 3/4 in. knockouts, built-in grounding, and a compact profile (6 in. H x 4 in. W x 2.63 in. D) that fits in tighter spaces. Add to that a spring-loaded weatherproof cover that snaps shut to block insects, debris, and moisture, and you have a reliable, safe solution. Proudly made in the USA (in partnership with Reliance Controls), the XP50PB pairs with manual transfer switches or interlock kits for secure power routing when utility power is lost.
