Eaton PFTWFA 4Q10AR58 Ruff-IN Assembly - NEMA 1
Part Number: PFTWFA 4Q10AR58
Quick Summary
The Eaton Ruff-IN assembly is a rugged conduit box system for industrial enclosures, enabling fast, secure wiring access. For field crews, misalignment and labor-intensive field fabrication are common pain points that slow critical wiring projects. Built to NEC/CEC standards, with a NEMA 1 rating and UL-listed options, this Ruff-IN assembly delivers reliable protection in ordinary locations. Coupled with integrated clamps, an MC connector, and a single-gang raised mud ring, it accelerates installation while maintaining code compliance. The design supports 14-1/2"–25" stud spacing and a 4" box with welded construction, offering practical compatibility with wide flange mounting plates. This combination translates to reduced install time and predictable, repeatable wiring quality for projects with tight schedules.

FAQs
The assembly uses a wide flange telescoping bracket designed to accommodate 14-1/2"–25" stud spacings with a mounting plate, plus a single-gang raised mud ring for clean wiring access. For best results, align the face bracket offset and position the MC connector to minimize cross-conduit bending, ensuring secure clamps and proper knockouts are used for all circuits.
The integral MC connector eliminates the need for separate adapters, reducing part count and potential leak points. The 5/8" raised mud ring provides proper conduit depth and grounding path, contributing to safer terminations and easier gasketing in panel assemblies.
Yes. The product is rated for Ordinary/Non-Hazardous Locations with a NEMA 1 enclosure rating, aligning with NEC/CEC standards. It is ideal for general purpose control panels and machinery enclosures in typical factory settings, not for hazardous or outdoor environments without additional protection.
The assembly adheres to NEC/CEC standards, carries a NEMA 1 rating, and UL certification options are available via Ruff-IN product documentation. These certifications help ensure compliance during audits and simplify procurement for code-driven projects.
By combining a 4" box, built-in clamps, MC connectivity, and adjustable stud spacing, the unit reduces field assembly time and part count. This translates to faster commissioning, less on-site troubleshooting, and lower lifecycle costs due to fewer wiring errors and rework.
