Eaton GBK Series Ground Bar Kit for CH Loadcenters

The Eaton GBK Series Ground Bar Kit is a ground bar accessory engineered for use with Eaton CH loadcenters, providing a reliable point of connection for grounding and bonding conductors inside the panel. The GBK family is offered in multiple terminal configurations, from 5 to 21 terminals, with either a standard lug or a 1-2/0 lug depending on the configuration selected, so installers can match the correct ground bar to their specific CH (and in many configurations, BR) loadcenter. This kit is designed for direct installation into compatible loadcenter enclosures and is fitted with a lug for secure conductor termination, keeping wiring organized and code-compliant in residential and light commercial panel applications.

Key Features

  • Terminal Configurations: Available with 5, 10, 13, 14, or 21 terminals to match the grounding conductor count required by the loadcenter.
  • Lug Options: Offered with a standard lug (GBK5/10/13/14/21) or a 1-2/0 lug (GBK1020/1420/2120/520) to accommodate a range of conductor sizes for dependable termination.
  • Mounting: Designed for direct fit into compatible Eaton CH loadcenters, with several configurations also suited to BR loadcenters.
  • Compact Dimensions: Low-profile design for a clean fit inside the panel.
  • Loadcenter Compatibility: Used with Eaton CH loadcenters; confirm the correct GBK ground bar for your specific loadcenter configuration, including special guidance for 2/4, 4/8, and 8/16 circuit loadcenters.
  • Panel-Ready Design: Purpose-built as a CH loadcenter and breaker accessory to simplify grounding during installation or panel service.

Eaton GBK5 – Frequently Asked Questions

1) Will an Eaton GBK ground bar fit a BR loadcenter, or is it CH only?
Several GBK bars are listed for use with both CH and BR loadcenters: GBK5, GBK10, GBK13, GBK14, GBK21, and the 1-2/0 lug versions GBK1020, GBK1420 and GBK2120. Other configurations in the family are called out for CH loadcenters only, including the ones specified for 4/8 and 8/16 circuit panels. Match the bar to the panel you actually have rather than assuming the whole series crosses over.
2) I have a CH 8/16 circuit loadcenter. Which GBK ground bar is called out for it?
For CH loadcenters in the 4/8 and 8/16 circuit range, the GBK bars listed are the 5, 10, 13, 14 and 21 terminal standard lug versions. That is a different call-out from the 2/4 circuit panels, which are restricted to the GBK5 or GBK520. Choose the terminal count off your grounding conductor count within that group.
3) Can I use an Eaton GBK ground bar in a Square D QO panel?
No. The GBK is built to the mounting and terminal arrangement of Eaton CH loadcenters, with some versions also fitting Eaton BR. A QO panel takes Square D's own accessories, and mixing brands of panel interior parts is not a listed use. For Square D QO panels ZenSupply carries QO series accessories such as the PK4MB2LA retaining bracket kit; for grounding, order a Square D QO ground bar.
4) Can I land the neutrals on an Eaton GBK ground bar in a subpanel?
No. The GBK is a ground bar, bonded to the enclosure, and it is there for equipment grounding and bonding conductors. In a subpanel the neutrals have to stay isolated on the insulated neutral bar; only the grounds go on the GBK. That separation is exactly why you add a ground bar to a subpanel in the first place. In the service disconnect enclosure the two are bonded together, which is a different situation.
5) Can a Square D PK4MB2LA be used in place of an Eaton GBK ground bar?
No. The Eaton GBK is a ground bar kit that lands grounding and bonding conductors inside an Eaton CH loadcenter, in 5, 10, 13, 14, or 21 terminal counts with either a standard lug or a 1-2/0 lug. The Square D PK4MB2LA is a QO load center retaining bracket kit for the 100A-125A right side, a mounting bracket rather than a conductor termination point, so it provides no ground terminals and does not substitute for a GBK5, GBK10, GBK13, GBK14, or GBK21.
6) How many terminals do I need on a ground bar for my panel?
The GBK family runs 5, 10, 13, 14 and 21 terminals. Count every equipment grounding conductor coming into the panel plus the bonding jumper, then size up from there so you are not doubling conductors under one screw. A 21 terminal bar such as the GBK21 covers a full size residential panel; the GBK5 suits a small subpanel or a 2/4 circuit CH loadcenter. Nothing stops you fitting more than one bar if the panel has the mounting positions.
7) Does an Eaton CH loadcenter come with a ground bar, or do I have to add one?
The GBK is sold as a separate kit, an accessory that installs into the loadcenter enclosure to give the equipment grounding and bonding conductors a landing point. On a new install or a service upgrade, order it alongside the panel. It is also the part you buy on its own when an existing CH panel has run out of ground terminals during a circuit addition.
8) I am standardizing ground bars across a building's Eaton CH panels. Can I spec one part number?
Only if the panels are all the same size class. The bar has to match the loadcenter: 2/4 circuit CH panels take the GBK5 or GBK520 specifically, while 4/8 and 8/16 circuit CH panels accept the 5 through 21 terminal standard lug bars. If your panels vary, the workable approach is to standardize by terminal count within each class, for instance GBK21 on the full size panels and GBK5 on the small ones, so the stockroom carries two part numbers instead of six.
