Square D PK5GTA – Frequently Asked Questions

1) How many terminals does the Square D PK ground bar kit come with?
Two sizes: a 23-terminal bar (PK23GTA) and a 5-terminal bar (PK5GTA). Pick the 23-terminal version when you are landing a full panel of equipment grounds in a new or retrofitted load center, and the 5-terminal version when you only need to pick up a handful of grounds in a small panel or after a subpanel addition.
2) Is the Square D PK ground bar kit UL Listed for panel inspections?
It is UL 67 Listed and CSA rated, and complies with IEC standards. UL 67 is the panelboard standard, so the kit is evaluated as part of the load center assembly rather than as a loose accessory, which is what an inspector looks for on a field-installed ground bar.
3) Can I use this ground bar kit in an Eaton or ABB panel?
No. The PK Series kit is engineered for Square D QO and Homeline load centers, and the mounting holes and screws are matched to those panels. For an Eaton CH load center, the Eaton CH Ground Bar Kit with 21 terminals is the correct accessory, and ABB panels take the ABB TGK Series 4-hole equipment ground bar kit.
4) Can an Eaton CH ground bar kit be used in a Square D QO or Homeline load center?
No. The Eaton CH Ground Bar Kit is a 21-terminal aluminum bar built for Eaton's CH panel platform, and its mounting pattern follows that enclosure. The Square D PK Series ground bar kit is the equipment ground bar assembly engineered for QO and Homeline load centers, ships with 2 mounting screws, and is compatible with any Square D QO circuit breaker. For a QO or Homeline panel, use the PK kit - PK23GTA for 23 terminals or PK5GTA for 5.
5) I only need to land a few equipment grounds in a small panel - is there a smaller option than the 23-terminal Square D ground bar?
Yes. The Square D PK Series kit is offered as PK5GTA with 5 terminals alongside the 23-terminal PK23GTA, so a subpanel or a small retrofit that only needs a handful of grounds does not require the full 23-terminal bar. Both are the same PK Series accessory for QO and Homeline load centers with the straight-in wiring design. If the count is even smaller, the ABB TGK Series kit is a 4-hole equipment ground bar, but it is an ABB accessory rather than a Square D one.
6) What is the difference between the ABB TGK ground bar kit and the Square D PK ground bar kit?
The ABB TGK Series kit is a 4-hole equipment ground bar, so it lands four conductors. The Square D PK Series kit is a QO/Homeline load center accessory offered in 5-terminal and 23-terminal configurations, accepts AWG 14 through AWG 4 copper and AWG 12 through AWG 4 aluminum conductors, and is UL 67 Listed and CSA rated. Choose by the panel brand the bar is mounting into and by how many grounds the job actually has.
7) Is the Square D PK ground bar kit a genuine Schneider Electric part and where is it made?
It is a genuine Square D / Schneider Electric accessory, made in the United States. For property managers and institutional buyers standardizing a building on QO or Homeline gear, that keeps the panel listing intact rather than relying on a third-party bar.
8) Is this ground bar kit RoHS compliant and mercury free?
Yes. The PK Series kit is RoHS EUR compliant, mercury free, and free of toxic heavy metals, which is what government, healthcare, and education procurement specs usually ask for on electrical accessories.
