3M Fork Terminal for #10 Stud

This vinyl-insulated fork terminal accepts 14 AWG copper wire and fits a #10 stud. The crimp barrel features a funnel entry and butted seam for reliable termination. It is rated for 1,000 V maximum voltage and carries CSA and UL certifications. Suitable for electrical panel work and general wiring tasks.

Thermal and Electrical Ratings

The insulation withstands a maximum operating temperature of 221 degrees F during normal operation. Blue vinyl material provides dielectric protection up to the rated voltage. Copper contact material ensures consistent conductivity across the crimped connection. No active cooling or power draw considerations apply to this passive component.

Sustained Load Behaviour

Under continuous electrical load the terminal maintains contact integrity within the 1,000 V and 221 degrees F limits. The butted seam barrel resists separation during prolonged thermal cycling. Crimp quality depends on using compatible tooling such as TH-440, TH-450 or TR-490 models. Not intended for applications exceeding the stated wire gauge or temperature rating.

Questions about this item

How do I crimp the 14 AWG fork terminal onto the wire without damaging the vinyl insulation?

Strip the conductor to match the 0.25 in barrel length, insert fully into the funnel barrel, then crimp with a ratchet tool calibrated for 14 AWG; the butted seam requires even pressure all round to avoid splitting the vinyl sleeve.

When should I replace a fork terminal that has been in service on a 1,000 V circuit?

Replace any terminal showing cracked blue vinyl, discoloured copper, or a loose fit on the #10 stud; the 221 °F temperature rating means prolonged heat cycling can embrittle the insulation before the crimp itself fails.

What is the first limitation I will hit when running continuous current through this #10 stud fork terminal?

The 14 AWG conductor and 0.25 in barrel set the ampacity ceiling; sustained loads that push the copper above 221 °F will degrade the vinyl insulation before the crimp or stud connection becomes the weak point.
