Overview

The NSI Industries RSK-500 Easy-Splice Direct Burial Splice Kit provides a reliable, UL486D-listed solution for in-line splicing of copper and aluminum cables ranging from 2/0 AWG to 500 MCM. This kit features a mechanical set-screw connector pre-filled with oxide inhibitor to prevent corrosion and ensure long-term conductivity, paired with an EPDM rubber insulating cover that delivers a watertight, UV-resistant seal for direct burial applications. Rated for 600 volts, the RSK-500 is ideal for outdoor environments where exposure to moisture, soil, and UV radiation is common. Designed for durability and ease of installation, the RSK-500 eliminates the need for heat-shrink or tape-based sealing methods. The EPDM rubber cover rolls on quickly and forms a secure seal over the connector, providing insulation and environmental protection without the complexity of traditional splicing techniques. This makes it particularly suitable for applications where gas or electric heating devices are not approved, such as street lights, motor connections, irrigation systems, HVAC units, and outdoor lighting. The kit’s dual-rated compatibility with both copper and aluminum cables ensures versatility across a wide range of electrical systems, reducing inventory requirements and simplifying procurement. With a connector length of 3.19 inches and a standard carton quantity of 6 units, the RSK-500 is optimized for efficient bulk handling and storage. The UL486D listing confirms compliance with stringent safety and performance standards, making it a trusted choice for professionals who demand reliability in critical infrastructure projects. Key benefits include immediate cable energization after installation, resistance to environmental stressors, and a secure seal that meets RUS acceptance criteria for secondary taps or splices. Whether used in municipal street lighting, agricultural irrigation, or commercial HVAC systems, the RSK-500 delivers a robust, low-maintenance solution for permanent cable splices in harsh conditions.
