Burndy KC22 – Frequently Asked Questions

1) What wire sizes does the Burndy KC22 grounding connector accept?
The KC22 takes stranded grounding conductors from 10 AWG through 3 AWG (listed as 10-3 Str). That covers most equipment grounding conductors and bonding jumpers on commercial panel work. It is a single-conductor connector, so one grounding conductor per unit, not two runs under the same lug.
2) Will the KC22 fit a 1/2 inch ground rod or stud?
The KC22 is built around a 15/32 inch post size, which is the nominal fit for the standard 1/2 inch grounding stud, rod, or bus connection point. If your post or stud measures larger than that, this is the wrong connector and you need a clamp sized to the actual post diameter.
3) Is the Burndy KC22 the right connector for a grounding electrode conductor at a ground rod?
Yes, within its range. The KC22 is a grounding connector for terminating a 10 AWG to 3 AWG stranded conductor onto a 15/32 inch post, which covers ground rod, stud and bus terminations as well as panelboard and switchgear bonding points. If your grounding electrode conductor is larger than 3 AWG (a 2 AWG or 4/0 run to a service, for example), step up to a clamp rated for that size.
4) Do I need a crimping tool to install the Burndy KC22?
No tool beyond a wrench or driver. The KC22 is a mechanical connector, so it is tightened in the field and does not require a hydraulic or dieless crimper. That is the practical reason to pick it over a compression grounding lug when you only have a handful of terminations to make and no press on the truck.
5) Can I land two ground wires in one KC22 connector?
No. The KC22 is configured for 1 Co, one conductor per connector. For two grounding conductors you need two KC22s or a connector rated for multiple conductors. Doubling wires into a single-conductor lug is not a connection you want on a grounding electrode system.
6) Is the KC22 a mechanical lug or a compression connector?
Mechanical. The conductor is clamped and tightened rather than crimped, so it can be installed, loosened and re-terminated in the field. Compression grounding connectors give a permanent, tool-verified crimp and are often what a spec calls for on switchgear or utility work, so check the drawing before substituting one type for the other.
7) How is the Burndy KC22 packaged, and can I order a single piece?
It ships 1 PC, a single connector, so you can buy exactly the count a panel or job needs instead of a carton. Useful for MRO stocking where you want a few on the shelf for panelboard and switchgear grounding terminations.
