Overview

The ABB ICS70-1 Series Aluminum Service Entrance Compression Splice (SKU: ICS70-1) is a high-integrity, compression-type connector designed for permanent, low-resistance joints between aluminum (AL) and copper (CU) conductors. This splice accommodates a wire range from 2 AWG to 25/32" diameter, with End A sized for 2 ASCR conductors (1-2 stranded, red color-coded) and End B supporting 8 stranded or 6 solid conductors (green color-coded). The 5/8" die ensures a secure crimp with uniform compression, minimizing thermal expansion and oxidation risks common in aluminum connections. This splice is UL-listed for service entrance applications, meeting NEC requirements for outdoor and indoor installations where aluminum-to-aluminum or aluminum-to-copper transitions are required. It is ideal for utility service drops, meter sockets, and distribution panels where code-compliant, long-term conductivity is critical. The aluminum construction resists corrosion and matches thermal expansion coefficients of AL conductors, reducing cold flow and joint degradation over time. Key applications include residential and commercial service entrances, renewable energy systems (solar/wind), and industrial power distribution where mixed-metal conductor compatibility is necessary. The red/green color coding simplifies installation and inspection, while the compression design eliminates the need for solder or mechanical screws, reducing labor time and improving reliability. For installations requiring compliance with NEC 310.106(C) and UL 486A-B standards, the ICS70-1 provides a tested, field-proven solution.
  • UL-listed for service entrance and outdoor use per NEC standards
  • Handles 2 ASCR (1-2 stranded) at End A and 8 stranded/6 solid at End B
  • 5/8" die ensures consistent compression for low-resistance joints
  • Aluminum construction matches thermal expansion of AL conductors
  • Red/green color coding for easy identification and installation
