Electrical Grounding Connector

The Burndy K2C25 is a bronze mechanical split-bolt connector designed for grounding applications in electrical and industrial installations. It accepts a single grounding wire ranging from 2 to 1/0 AWG solid or 2 to 2/0 AWG stranded conductor. The connector carries UL listing for direct burial use. It suits electricians and contractors requiring a code-compliant grounding termination.

Conductor Range and Torque

The single specification that determines fit is the conductor range of 2 to 1/0 AWG solid and 2 to 2/0 AWG stranded wire with a required installation torque of 480 in-lb. The thread size is 1/2 in.-13. Installers must verify the wire gauge and torque capability before selection. An incorrect gauge or insufficient torque will compromise the grounding connection.

Thermal and Electrical Performance

The leaded bronze alloy body provides low-resistance conductivity for fault-current paths while resisting corrosion in buried or exposed environments. Normal operation generates negligible heat when torqued to 480 in-lb on the specified wire range. The mechanical design requires no external power and produces no audible noise during service.

Questions about this item

How does the 2.43in overall length affect the space needed inside a grounding enclosure?

The connector measures 2.43in long and 3/4in wide, so allow at least that much clearance plus room for the conductor and a torque wrench when planning the enclosure layout.

What does the 1/2-13 thread size cap in practice for conductor compatibility?

The 1/2-13 stud accepts one grounding conductor from 2 to 1/0 AWG solid or 2 to 2/0 AWG stranded, matching the listed wire range.

What physical mounting provisions does the split-bolt design require?

It installs as a mechanical split bolt: insert the conductor, then tighten the nut to 480 in-lb; no special brackets or crimp tools are needed.
