Questions about this item

How much current can the 2,000 V rating actually carry in a 4 AWG circuit?

The terminal is rated for 2,000 V maximum voltage with 4 AWG copper wire; ampacity depends on the wire insulation and installation method, not the terminal itself.

What does the CSA LR31212 and UL 587H E52164 listing cover for this connector?

These certifications confirm the bare copper, tin-plated terminal meets North American safety standards for crimp-type wire connectors up to 2,000 V.

Will the 5/16 in stud hole and 0.68 in tongue fit a standard automotive battery post?

The 5/16 in stud size matches many battery and bus-bar bolts; the 0.68 in tongue width and 0.56 in barrel length suit 4 AWG cable crimps.
