Overview

The ABB CSC78 is a 2-inch aluminum service entrance compression splice designed for reliable connections in electrical distribution systems. Rated for 1/0 AWG aluminum or copper conductors (stranded), this splice features dual-rated compatibility for versatile applications. The yellow end caps indicate conductor compatibility, with End A and End B both supporting 1/0 ASCR or 1/0 stranded wires. The splice uses a 5/8" die for compression, ensuring a secure and low-resistance connection. Manufactured by ABB Installation Products, the CSC78 meets industry standards for service entrance applications, including residential, commercial, and light industrial installations. Its compression design eliminates the need for soldering or additional tools beyond a standard compression tool, reducing installation time and labor costs. The C2BB cover provides insulation and protection, meeting NEC requirements for service entrance equipment. Ideal for splicing main service conductors, branch circuits, or grounding applications where aluminum or copper conductors are present. The splice’s compact design allows for installation in tight spaces, while its durable aluminum construction ensures long-term performance in outdoor or indoor environments.
