Panduit EV10-56FB-Q StrongHold™ Fork Terminal
The Panduit EV10-56FB-Q is a vinyl-insulated fork terminal designed for terminating 12-10 AWG copper conductors to 5/16-inch stud connections. Part of the StrongHold™ series, this terminal features a zinc-plated brass barrel and tongue for corrosion resistance in commercial power distribution, battery bank, and UPS installations. The funnel-entry barrel design guides stranded wire during crimping, reducing prep time and ensuring consistent mechanical strength across high-volume panel builds. UL Listed 587H (E52164) and CSA Certified (LR31218) for compliance with NEC Article 110.3(B) and Canadian Electrical Code requirements.
Key Features
- 12-10 AWG conductor range accommodates common branch circuit and control wiring
- 5/16" stud size fits standard terminal blocks, contactors, and bus bars
- Vinyl insulation rated for 600V applications, color-coded blue for quick gauge identification
- Zinc-plated finish resists oxidation in HVAC equipment rooms and damp locations
- Funnel-entry barrel accepts stranded copper without wire fanning or strand breakage
- 1.2" overall length provides adequate clearance in crowded terminal strips
- UL 587H and CSA LR31218 certifications support inspector approval on commercial projects
Fork terminals remain the preferred choice for connections requiring periodic inspection or reconfiguration—motor control centers, battery strings, and any junction where removing the conductor without loosening the stud is impractical. The EV10-56FB-Q's forked tongue slides under a 5/16-inch screw or stud terminal, allowing the connection to be tightened while the wire remains captured. This eliminates the need to fully remove mounting hardware during maintenance cycles, a critical time-saver in energized or hard-to-reach enclosures. The vinyl insulation barrel extends close to the tongue, minimizing exposed metal and reducing phase-to-phase or phase-to-ground clearance requirements in tight panel layouts.
Panduit's StrongHold™ barrel geometry is optimized for hex-crimp tools using B-die configurations. The brass barrel's knurled inner surface grips each wire strand during compression crimping, creating a gas-tight joint that maintains low resistance over decades of thermal cycling. Zinc plating on both the barrel and the forked tongue provides sacrificial corrosion protection in environments with airborne contaminants—salt spray from coastal sites, sulfur compounds near industrial processes, or condensation in outdoor battery cabinets. The blue vinyl insulation is rated for 105°C continuous operation and remains flexible across a wide temperature range, preventing cracking in freezer rooms or embrittlement in rooftop equipment pads.
The 25-piece package quantity aligns with typical branch circuit and control panel builds—motor starter assemblies, fire alarm control panels, and access control power supplies often require one to three fork terminals per circuit. Bulk 5,000-piece cartons support facility-wide electrical standard stock programs and industrial panel fabrication lines. For data center battery plant installations, UPS output distribution panels, and backup generator transfer switch terminations, the EV10-56FB-Q delivers the field-proven combination of stud-style serviceability, code compliance, and long-term reliability that electrical contractors and facility engineers expect from Panduit's terminal portfolio.
