Eaton ACC50 Combination Coupling - EMT to AC/MC/FMC
Part Number: ACC50
Quick Summary
ACC50 is a combination coupling that connects EMT conduit to AC/MC/FMC cables in industrial wiring applications. This tool-free design reduces installation time and minimizes misalignment, helping electricians avoid costly rework on busy factory floors. It delivers reliable, compression-based connections rather than traditional threaded fittings, improving conductor integrity in everyday environments. The product carries NEC/CEC compliance with ordinary/non-hazardous location ratings and UL Canadian certifications, giving teams confidence across multi-site builds. By pairing steel construction with a compact 2.09 inch length and 1.23 inch height, ACC50 helps control inventories and simplify maintenance. For contractors and integrators, it offers compatibility with EMT, AC/MC, and FMC conduits, accelerating project timelines while maintaining safety standards.

Eaton Specification Sheet - ACC50
Feature: EMT to AC/MC/FMC compatibility enables a single, secure transition from conduit to cable assemblies. Business impact: fewer parts, reduced field inventory, and faster installs, which translate to lower labor costs and shorter project schedules. Application: ideal for panel wiring, machine interconnects, and device terminations in factory automation environments. Feature: Steel construction provides rugged reliability under vibration and temperature swings common in industrial plants. Business impact: long service life reduces maintenance cycles and replacement parts, improving total cost of ownership. Application: suitable for durable conduit connections in control panels, enclosures, and equipment bays. Feature: Combination type with EMT compression to saddle clamp simplifies mounting and alignment. Business impact: minimizes rework due to misfit or misalignment, enhancing first-pass assembly quality. Application: preferred for tight spaces where connector orientation and secure saddle-clamp connections matter most. Feature: NEC/CEC compliance and Ordinary/Non-Hazardous location rating, plus UL Canadian certification, provide regulatory confidence. Business impact: mitigates compliance risks, supports multi-region builds, and accelerates procurement approvals. Application: meets standards for technically demanding installations across US and Canada, helping engineers standardize fittings across sites.

FAQs
ACC50 supports EMT, AC/MC, and FMC conduits in a 1/2 inch to 1/2 inch trade size. The steel combination coupling uses an EMT compression method with a saddle clamp to simplify the transition between conduit and cable assemblies, making it ideal for panel wiring, machinery interconnects, and other industrial wiring points where fast, reliable connections are required.
ACC50 reduces installation time by eliminating extra fittings and mitigating misalignment risks. Its tool-free compression design allows quick, secure connections, especially in crowded or tight spaces. The compact 2.09 inch length and 1.23 inch height further streamline installs, lowering labor costs and helping projects stay on schedule.
ACC50 is rated for Ordinary/Non-Hazardous Locations under NEC/CEC and has UL Canadian certification. It is not intended for hazardous locations or exposed outdoor use unless additional protective measures are applied. For multi-site deployments in compliant environments, ACC50 provides a standardized solution.
ACC50 complies with NEC/CEC standards for non-hazardous locations and carries UL Canadian certification for combination couplings. The UPC 784564003195 helps product identification. These certifications support regulatory acceptance in North American installations and facilitate cross-border procurement.
ROI comes from fewer parts, reduced labor time, and lower maintenance due to its robust steel build. ACC50 supports multiple conduit types, reducing inventory complexity and replacement costs from vibration or impact. Over a project lifecycle, these factors translate to measurable cost savings and more predictable maintenance planning.
