Bronze Bolt Connector for Grounding

The Burndy K2C22B1 is a split-bolt grounding connector made from leaded bronze alloy. It accepts a single grounding wire ranging from 10 to 2 AWG solid or 10 to 3 AWG stranded. The mechanical connector carries a 3/8-16 thread and measures 2.12 inches overall length. It is UL Listed for direct burial under UL467.

Installation limits and torque requirement

The connector must be tightened to 280 in-lb to meet its listing. It is rated for one conductor only, so multiple wires cannot be combined under the bolt. The 10–3 AWG stranded and 10–2 AWG solid range defines the practical wire sizes that fit. No other conductor counts or gauge combinations are supported by this listing.

Verify wire gauge and burial rating before ordering

Confirm that your grounding conductor falls within the 10–3 AWG stranded or 10–2 AWG solid range. Ensure your application requires a direct-burial rated connector per UL467. The 3/8-16 stud must match the mating hardware in your assembly. This connector is not suited for multi-wire terminations or gauges outside the stated range.

Questions about this item

Which wire sizes does the K2C22B1 accept?

The connector fits 10 to 2 AWG solid and 10 to 3 AWG stranded conductors for a single grounding wire.

What does the 280 in-lb torque rating mean for installation?

Tighten the 3/8-16 stud to 280 in-lb to achieve the mechanical connection the UL listing requires.

How does the 3/8-16 thread size affect compatibility?

The 3/8-16 stud matches standard grounding hardware, so the bolt fits common lugs and bus bars without adapters.
