800 A bus rating and 10 kAIC interrupt rating enable the R1048 HEE to handle high-current feeders with robust fault-current tolerance. This reduces upstream protection coordination issues while enabling safer, faster clearance during faults. In practice, you can run four conductors with a 1/0-250 MCM feeder strategy, keeping terminations tidy and accessible for service. The cabinet dimensions of 6 in depth, 28.5 in height, and 48 in width deliver a compact footprint that fits crowded electrical rooms and aligns with other B-Line enclosures, reducing space cost and installation time. Line lug size is #4 - 600 MCM and load lug size is 5/16 inch, supporting flexible feeder terminations and quick field modifications. The galvanized steel body with ANSI 61 gray paint provides corrosion resistance, while aluminum bussing enhances conductor performance and reduces heat buildup. With NEMA 3R rating and UL Listed certification, the enclosure is suitable for both indoor and protected outdoor environments and compatible with standard mounting holes for easy installation. Together these features deliver measurable efficiency gains, safer terminations, and reduced maintenance costs in high-current, low-voltage distribution.
