Overview

The ABB CS77 is a 2-inch aluminum service entrance compression splice designed for reliable connections between 1/0 ASCR (yellow) and 2 6/1 or 7/1 ASCR (red) conductors. This splice supports both aluminum-to-aluminum (AL-AL) and aluminum-to-copper (AL-CU) applications, making it versatile for residential and commercial service entrance installations. The CS77 uses a 5/8-inch die for compression, ensuring a secure, gas-tight connection that resists corrosion and maintains conductivity over time. Its compression design eliminates the need for soldering or mechanical fasteners, reducing installation time and labor costs. The splice is compatible with 1/0 stranded conductors at End A and 1-2 stranded conductors at End B, covering common service entrance wire ranges. ABB’s compression splices are UL-listed and manufactured to meet NEC requirements for service entrance applications. The aluminum construction provides lightweight durability while maintaining compatibility with copper conductors when used with appropriate joint compounds. This splice is ideal for utility companies, electrical contractors, and industrial installations requiring dependable, code-compliant connections.
