Burndy tn186f Nylon Fork Terminal 22-18 Awg 600V

Product Description

The BURNDY tn186f is a nylon-insulated fork terminal designed for wire gauges from 22 to 18 AWG. The barrel is constructed from pure electrolytic copper with a long brazed seam and deep V-groove inner serrations, delivering optimum conductivity, low resistance, and reliable holding power after crimping. The fork tongue design allows the screw to remain in place during termination — only a partial loosening is needed, which speeds up installation. Rated for up to 600 volts and 105 degrees C, this terminal suits electricians and low-voltage technicians working on control panels, equipment wiring, and terminal block connections.

The tn186f is suited for residential and commercial electrical applications where secure, reusable wire terminations are required. The fork tongue configuration allows two or more terminals to be stacked on a common stud, making it practical for multi-circuit termination points. Electro-tin plating over the copper barrel provides durable corrosion resistance for long service life in both indoor and environmentally exposed enclosures. An inspection hole and skive allow a quick visual check to confirm proper wire insertion before the crimp is set.

Key Features

• Pure electrolytic copper barrel for maximum conductivity and ductility
• Long brazed seam barrel with deep V-groove inner serrations for reliable crimp holding power
• Fork tongue design allows termination without fully removing the mounting screw
• Two or more terminals can be stacked on a common stud
• Electro-tin plating for long-lasting corrosion resistance
• Inspection hole and skive for visual verification of proper wire insertion

Compatibility

Designed as an OEM-style nylon fork terminal for use with 22 to 18 AWG wire in standard electrical and control wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified technicians. De-energize all circuits and verify zero voltage before terminating wires. Strip wire to the appropriate length, insert fully through the inspection hole, and apply a proper ratchet or hex-type crimp tool rated for insulated terminals. Follow applicable NEC guidelines for terminal selection, conductor sizing, and torque requirements at the mounting stud.
