Overview

This tee connector accommodates main and tap conductors both rated 4/0 AWG stranded aluminum-copper, ensuring compatibility with standard 29/32" outside diameter (OD) cables. The main conductor length measures 3 inches, while the tap branch extends 6 inches, providing flexibility in tight junction box installations. The connector features TX dies (76, 249, 840, 11A) for precise compression, ensuring a gas-tight, corrosion-resistant joint that meets NEC requirements for aluminum-to-copper transitions. Integrated oxide inhibitor paste prevents galvanic corrosion, extending service life in harsh environments. Distinctive pink caps identify the connector for quick visual verification during installation and maintenance. A factory-applied dimple ensures proper alignment and compression force distribution, eliminating guesswork during crimping. This product is ideal for power distribution panels, switchgear, and renewable energy systems where reliable, code-compliant conductor taps are required. Compatible with standard hydraulic or battery-powered crimping tools, the AT 4/0-4/0 simplifies field installations while maintaining long-term electrical integrity.
