Overview

The ABB RS403 is a 6-inch aluminum service entrance compression reducing splice designed for reliable connections between large aluminum conductors (400-336 kcmil) and smaller stranded conductors (4/0 AWG). This splice is dual-rated for both aluminum and copper conductors, eliminating the need for separate components when transitioning between conductor types. The RS403 uses ABB’s B20AH dies for consistent, high-integrity compression joints that meet NEC requirements for service entrance applications. With a compact 1-5/16-inch size, it fits standard junction boxes and enclosures while providing a secure mechanical and electrical connection. Ideal for utility, commercial, and industrial installations where conductor size transitions are required, the RS403 ensures long-term performance with corrosion-resistant aluminum construction and UL-listed compression technology. No additional tools beyond standard compression equipment are required for installation.
