Overview

The ABB Installation Products U 1 N 104 Insulated Aluminum Service Entrance Compression Splice is engineered for reliable connections in electrical distribution systems. This splice is designed for joining aluminum to aluminum or aluminum to copper conductors, offering versatility for various applications. The U 1 N 104 features a yellow conductor termination for Conductor A, specified as 1/0 ACSR or 1/0 Stranded aluminum. Conductor B is indicated by an orange termination, accommodating 4 ACSR, 2 Solid, or 4 Stranded aluminum conductors. The splice itself measures 2-1/8 inches in length with a 37/64 inch diameter. When equipped with its sleeve and caps, the overall dimensions increase to 3-1/4 inches in length and 47/64 inch diameter, providing robust protection and strain relief. A key feature of this splice is its 'Oil Stop' design, which prevents the migration of insulating oils, ensuring the integrity of the connection and preventing potential failures. Installation of the U 1 N 104 requires specific tooling. The recommended installing dies include CSA-22, 5/8, TU, and BG, ensuring a secure and permanent compression connection. This product, with SKU U 1 N 104, is a critical component for service entrance applications where dependable conductor joining is paramount. Its construction from aluminum ensures excellent conductivity and corrosion resistance, suitable for outdoor and exposed environments. The insulated design provides an additional layer of safety during installation and operation. ABB's commitment to quality in their Installation Products division is evident in the robust design and material selection of the U 1 N 104 splice, making it a trusted choice for utility and industrial electrical contractors.
