Eaton GBKP2120 – Frequently Asked Questions

1) Will an Eaton GBKP ground bar kit fit a CH or BR load center?
The GBKP ground bar terminal kit is built for Eaton CH and BR series plug-on neutral load centers, and it mounts in those enclosures without modification. If the panel in front of you is a Square D QO or Homeline, this is the wrong bar, that panel takes a Square D PK Series ground bar kit instead. Panel brand is the first thing to settle here, ground bar mounting holes and bus geometry are not shared across manufacturers.
2) How many terminals do I get on an Eaton GBKP ground bar, and which size do I need?
Four terminal counts are sold: 5, 10, 14, and 21. Count the equipment grounding conductors landing in the panel, one screw per conductor unless your local inspector permits otherwise, then add spare positions for future circuits. A 5-terminal GBKP5 suits a small sub-panel or a few added circuits; the 21-terminal GBKP21 is the one for a full residential service or a panel that is getting loaded out over time. Property managers standardizing across a building usually buy the larger bar so the same part covers every panel.
3) What does the CS suffix mean on Eaton ground bar kits like GBKP14CS?
CS is the clamshell. Kits ending in CS, such as GBKP10CS, GBKP14CS, GBKP1420CS and GBKP21CS, ship with a protective clamshell cover that snaps over the bar inside the panel. Ordering the plain GBKP14 gets you the bar without that cover. Where a panel is in a common area or a tenant space and you want the terminations shielded and tidy, spec the CS version.
4) Do I need to add a separate ground bar to a sub-panel, or can I use the neutral bar?
In a sub-panel the grounded (neutral) conductors and the equipment grounding conductors have to stay separated, so the sub-panel needs its own bonded ground bar. That is exactly what the Eaton GBKP kit provides in a CH or BR enclosure: a dedicated bar with 5 to 21 terminal positions for the equipment grounds, leaving the factory neutral bus isolated. In the service equipment itself the two may be bonded together, but adding the ground bar there is still common practice when the neutral bus runs out of screws.
5) Is the Square D PK ground bar kit a direct substitute for an Eaton GBKP ground bar kit?
No. The Square D PK Series ground bar kit is built as a load center accessory for Square D QO and Homeline enclosures, while the Eaton GBKP ground bar terminal kit is engineered for Eaton CH and BR series plug-on neutral panels. Ground bar kits are matched to the mounting provisions and clearances of the panel brand they are made for, so a QO/Homeline kit and a CH/BR kit are not interchangeable. Match the kit to the panel label: GBKP for an Eaton CH or BR can, PK Series for a Square D QO or Homeline can.
6) I am standardizing grounding accessories across a portfolio with both Square D and Eaton panels - what do I stock?
Two lines, not one. Eaton CH and BR plug-on neutral panels take the Eaton GBKP ground bar terminal kit, which is offered in 5, 10, 14 and 21 terminal counts under part numbers such as GBKP5, GBKP10, GBKP14 and GBKP21, plus clamshell versions like GBKP10CS and GBKP21CS. Square D QO and Homeline load centers take the Square D PK Series ground bar kit. A facility with mixed panel brands needs a stocking line for each; the terminal count is chosen from the number of equipment grounding conductors landing in that can, independent of brand.
7) What is the P suffix on an Eaton GBKP10P or GBKP14P ground bar kit?
P designates the plug-on neutral accessory version, sold as GBKP10P, GBKP14P and GBKP21P. These are the kits configured for Eaton's plug-on neutral CH and BR panels, where the neutral bus arrangement differs from an older style load center. Match the suffix to the panel you are actually working in rather than to what the last one took.
8) Can I add an Eaton GBKP ground bar to an existing panel during a service upgrade?
Yes, that is one of its main uses. The GBKP kit installs in an existing CH or BR plug-on neutral enclosure as well as in new construction, which is what makes it the standard fix when a panel retrofit adds circuits and the existing grounding terminations run out of room. It ships as a complete bar and clamshell kit on the CS versions, so there are no separate grounding accessories to chase down.
9) The panel is an Eaton BR but the truck only has a Square D PK kit - can I use it to finish the job?
Treat it as a different part, not a stand-in. The Square D PK Series kit is a ground bar accessory for QO and Homeline load centers, and the Eaton GBKP kit is the purpose-built ground bar for CH and BR plug-on neutral panels, sized to mount without modification in that enclosure. Drilling or adapting a foreign-brand bar into a listed panel is the kind of field modification an inspector will question. If the count is the only issue, the GBKP range covers 5 through 21 terminals, so a larger GBKP is usually the answer rather than a cross-brand bar.
