Eaton 656DC EMT compression connector - NEC/CEC
Part Number: 656DC
Quick Summary
Eaton 656DC EMT compression connector provides straight, non-insulated EMT terminations for reliable conduit runs. This reduces installation time and costly callbacks, especially where space is at a premium in control cabinets, machine rooms, and compact switchgear. Ideal for general wiring in industrial facilities needing quick, reliable terminations and code-ready fits that support ongoing maintenance programs. The zinc die-cast construction and 2-1/2 inch trade size deliver durability and easy field installation across industrial panels. Designed for dependable EMT connections in manufacturing, energy, and process environments, it supports efficient procurement and code compliance. Its compatibility with Crouse-Hinds series EMT fittings, straightforward orientation, and compact footprint reduce installation time in enclosures and raceways. This helps engineers shorten project schedules and lower field labor costs.

Eaton Specification Sheet - 656DC
Straight EMT compression design simplifies field assembly by providing a predictable alignment path for conduit runs in crowded panels, minimizing the need for rework during energization. This reduces installation time and costly callbacks, especially where space is at a premium in control cabinets, machine rooms, and compact switchgear. Ideal for general wiring in industrial facilities needing quick, reliable terminations and code-ready fits that support ongoing maintenance programs. The threadless compression interface eliminates thread damage and cross-threading risk, enabling technicians to secure conductors confidently in tight confines and crowded panels. Business impact includes faster terminations, improved seal integrity under vibration and temperature cycling, and reduced warranty calls related to leaks. Applications span high-demand environments such as conveyors, pumps, and power distribution panels where reliability, safety, and uptime are critical. Zinc die-cast construction provides robust mechanical protection and corrosion resistance for installations in ordinary/non-hazardous locations, resisting impact and weathering over long service life. Non-insulated design reduces component count in enclosures and minimizes thermal buildup at terminations, simplifying wiring schemas and reducing heat-related degradation. Pair with EMT fittings in the Crouse-Hinds series to streamline procurement, ensure compatibility across vendors, and accelerate project timelines.

Trade size of 2-1/2 inches and dimensions of 3.65 in length, 3.56 in width, and 3.36 in height enable ergonomic handling and predictable enclosure planning. Weight at 1.06 lb indicates a sturdy yet manageable field component for field crews, reducing fatigue during long installations. These specifications help with performance forecasting, spare-part planning, and cross-compatibility with standard EMT hardware, simplifying vendor selection. Code compliance is a priority with NEC/CEC standards, ensuring electrical installations meet current regulatory requirements and safety expectations. UL listings, including Canadian documentation, support cross-border projects and simplify audits, warranty validation, and safety certifications. Non-insulated terminations reduce field component counts while maintaining a robust grip and reliable conductivity in ordinary locations.

FAQs
The 656DC is designed for straight EMT conduit terminations in ordinary/non-hazardous locations, including control panels, machine enclosures, and industrial distribution setups. It supports 2-1/2 inch trade size and pairs well with Crouse-Hinds EMT fittings for consistent mechanical and electrical performance in standard industrial environments.
Install by inserting the EMT conduit into the compression connector until seated, then tighten as specified for compression fittings. Because this is threadless, alignment is maintained during tightening, reducing cross-threading risk. Verify the conduit is fully engaged and perform a quick pull test to ensure a secure, code-compliant termination.
656DC is designated for Ordinary/Non-Hazardous Locations. It aligns with NEC/CEC standards for general industrial wiring, but is not specified for use in Hazardous (Classified) environments unless otherwise noted by the manufacturer.
The connector complies with NEC/CEC standards and is UL-listed for Canada, providing regulatory alignment and cross-border documentation. This supports audits, safety certifications, and procurement in both U.S. and Canadian projects.
With a 2-1/2 inch trade size, zinc die-cast body, and a threadless, compression design, the 656DC simplifies field installations, reduces rework, and lowers spare-part complexity. Its UL Canada listing and catalog consistency streamline procurement and maintenance planning across multiple sites.
