  • Tin-plated copper barrel resists corrosion
  • Black polypropylene insulation identifies 16 AWG circuits
  • 5/8 in insertion length speeds panel wiring
  • Meets UL 486F, CSA C22.2 No. 291-14, DIN 46228
  • 500-piece pack supports high-volume assembly

Wire Ferrule for 16 AWG Copper

The Panduit FSD78-12-D is a crimp-style wire ferrule designed for 16 AWG copper conductors. It provides a reliable termination for generator parts and electrical supplies. The pack contains 500 pieces, supporting volume wiring tasks. Electricians and panel builders use it to prevent strand fraying in terminal blocks.

Tin-Plated Barrel Withstands 221 °F

The copper barrel features a tin-plated finish for corrosion resistance and consistent contact. Maximum operating temperature is rated at 221 degrees Fahrenheit. Polypropylene insulation remains stable under normal panel heat. The crimp termination creates a secure mechanical and electrical bond without soldering.

Black Insulation Identifies 16 AWG

Black polypropylene insulation covers the barrel for quick visual identification of the wire gauge. The insulation length is 5/8 inch and the barrel length is 0.26 inch. The ferrule meets CSA C22.2 No. 291-14, DIN 46228 and UL 486F standards. Buyers needing ferrules for other wire sizes or insulation colours must select a different part number.

Questions about this item

How do I crimp the Panduit FSD78-12-D ferrule onto a 16 AWG wire without damaging the 0.12 in barrel?

Strip the wire to the 5/8 in insertion length, seat it fully into the 0.12 in tin-plated copper barrel, then use a ratchet crimp tool matched to 16 AWG so the 0.26 in barrel compresses evenly without over-crimping the tin finish.

Will the black polypropylene insulation on these ferrules need replacement after repeated heat cycles near the 221 °F rating?

The insulation is rated to 221 °F maximum operating temperature; it does not require scheduled replacement, but inspect for discoloration or brittleness if the application regularly approaches that limit.

At what current level does the 0.08 in ferrule diameter become the limiting factor during sustained load?

The 16 AWG wire size and 0.08 in ferrule diameter set the ampacity ceiling; sustained loads above the 16 AWG rating will hit conductor heating limits before the tin-plated copper barrel or CSA C 22.2 No. 291-14 / UL 486F compliance margins are exceeded.
