Verify Wire Gauge and Torque Tooling

Before ordering, confirm that the existing grounding conductor falls within the 10 to 4 AWG solid or 10 to 5 AWG stranded range. Ensure a torque wrench capable of delivering 180 in-lb is available for proper installation of the 5/16 in. -18 thread stud.

Questions about this item

Does the KC20 bolt connector come with any grounding wire or lugs, or must those be purchased separately?

The connector is sold by itself; grounding wire in the 10 to 4 AWG solid or 10 to 5 AWG stranded range and any lugs must be sourced separately.

Should I choose this KC20 model or a different size for a 6 AWG stranded ground conductor?

This model accepts up to 5 AWG stranded, so 6 AWG stranded falls outside its range; select a larger split-bolt connector rated for that gauge.

What does the 180 in-lb installation torque mean when I tighten the bolt on a real job?

Tighten the 5/16-18 stud to 180 in-lb with a calibrated torque wrench to meet the UL 467 direct-burial listing requirements.
