Panduit F85-18-C Non-insulated Ferrule 4 Awg

Product Description

The PANDUIT F85-18-C is a non-insulated wire ferrule designed for use with 4 AWG conductors. Ferrules of this type provide a clean, crimped termination that consolidates stranded wire ends before insertion into screw-type or cage-clamp terminal blocks. The non-insulated design is suited for applications where the terminal block provides its own conductor retention or where insulation color-coding is not required. Licensed electricians and panel wiring technicians install this type of ferrule during control panel assembly, industrial wiring, and switchgear work to reduce loose strand contact faults and improve long-term connection reliability.

This ferrule is used in residential and commercial electrical panels, industrial control enclosures, and automation systems where terminal block wiring is standard practice. It is appropriate for use wherever 4 AWG stranded conductors must terminate cleanly into compression or screw-clamp terminals. The non-insulated body keeps the termination compact and compatible with tightly spaced terminal blocks commonly found in DIN rail-mounted assemblies.

Key Features

• Non-insulated design for compact termination in tightly spaced terminal blocks
• Sized for 4 AWG stranded conductors
• Crimped installation consolidates stranded wire ends and reduces loose-strand faults
• Sold individually, allowing precise quantity ordering for panel builds
• Suitable for screw-type and cage-clamp terminal block applications

Compatibility

Designed as an OEM-style termination ferrule for use with 4 AWG stranded conductors in standard screw-clamp and cage-clamp terminal block systems.

Installation Notes

Installation is performed by licensed electricians during panel assembly or field wiring. De-energize all circuits and follow NFPA 70 (NEC) lockout/tagout procedures before terminating conductors. Use a calibrated ferrule crimping tool matched to the ferrule size to achieve a proper crimp — hand-tightening without crimping is not an acceptable installation method. Inspect the crimped ferrule for conductor pullout resistance before securing the terminal block screw.
