3M 5815-B40 Lug

3M 5815-B40 Modular Splice Adapter is a large-diameter component in the 3M 5815 Modular Splicing System, delivering a fully shielded, separable connection for medium-voltage cable splices and dead-front terminations. It is designed to be used with the 5815 family to form a dead-front splice suitable for equipment such as switches, switchgear, and transformers, including installations where a shielded, reliable joint is required. The B40 variant accommodates insulation diameters from 1.080 to 1.280 inches (27.4–32.5 mm), enabling a range of conductor sizes within the same modular family. This adapter supports copper and aluminum conductors and is intended for integration with other 5815 components to allow future modifications without disturbing the live bolted connection. The 5815 system is engineered for durable, shielded splices in industrial electrical networks, providing a modular approach to expanding or modifying high-voltage cable terminations without replacing entire assemblies. Designed for use in industrial facilities and utilities, it forms a compact, modular splice that can be integrated with 3M's dead-front devices to simplify installation and future rework.
