Overview

The ABB TC124A Set Screw Connector (SKU: TC124A) is a heavy-duty, zinc-plated steel fitting engineered for secure, concrete-tight installations of 1-1/4" EMT conduit. Designed for industrial, commercial, and residential electrical systems, this connector eliminates the need for conduit threading while providing a permanent, vibration-resistant connection. The hardened hex head set screw ensures positive holding strength and ground continuity, meeting UL 514B, CSA C22.2 No. 18, and NFPA 70-1999 standards. The nylon-insulated throat reduces wire pulling effort by up to 50% and prevents insulation damage or first-thread stripping during installation. Certified by U.L. (File No: E-23018) and CSA (LR-2884, LR-4484), the TC124A is rated for concrete-tight applications and can carry ground fault currents up to 20,000 amps RMS. Its 2.250-inch length and durable construction make it ideal for demanding environments where reliability and code compliance are critical. Trust ABB Installation Products for electrical components that deliver consistent performance in both new construction and retrofit projects.
