ABB A-Series Isolated/Insulated Equipment Ground Kit
The ABB A-Series Isolated/Insulated Equipment Ground Kit provides standard isolated/insulated equipment grounds engineered specifically for ABB A-Series panelboards, factory supplied to match the panelboard's branch configuration. Each kit is sized for every 12 branch positions, with conductor accommodations for (11) 14-8 Cu or 12-8 Al and (3) 14-4 Cu or 6-4 Al, giving panel builders and electrical contractors a code-ready grounding solution matched to copper or aluminum branch circuit wiring. Because the kit is factory supplied with the panelboard, it integrates directly into the A-Series enclosure without field modification.
Key Features
- Panelboard Compatibility: Purpose-built for ABB A-Series panelboards, factory supplied to align with the panelboard's branch layout.
- Branch Position Coverage: Configured for each 12 branch positions, simplifying equipment grounding across multi-circuit panels.
- Standard Isolated/Insulated Design: Supplied as standard isolated/insulated equipment grounds, supporting isolated ground requirements common in sensitive electrical and electronic loads.
- Copper Conductor Range: Accommodates (11) 14-8 Cu and (3) 14-4 Cu conductors for standard copper branch wiring.
- Aluminum Conductor Range: Accommodates (11) 12-8 Al and (3) 6-4 Al conductors for aluminum branch wiring applications.
- Factory-Supplied Fit: Manufactured by ABB for direct compatibility with A-Series panelboard equipment ground provisions, eliminating guesswork on conductor sizing.
- Single-Unit Packaging: Packaged 1 EA for straightforward ordering alongside A-Series panelboard equipment.

ABB EGS12 – Frequently Asked Questions
1) How many branch circuits does the ABB EGS12 equipment ground kit cover?
The EGS12 ground kit is sized for each 12 branch positions in an ABB A-Series panelboard. If your panel has more than 12 branch positions, you order additional kits to cover the rest. Each kit ships 1 EA.
2) What wire sizes will the ABB EGS12 ground bar accept in copper and aluminum?
Copper: (11) terminations at 14-8 Cu plus (3) larger ones at 14-4 Cu. Aluminum: (11) at 12-8 Al plus (3) at 6-4 Al. So the three oversize ports are what you use for the larger feeders or a bonding conductor, and the eleven smaller ports handle standard branch circuit grounds.
3) Will this ABB ground kit fit a panelboard from another manufacturer?
No. The EGS12 is built specifically for ABB A-Series panelboards and is factory supplied to match the A-Series branch layout and equipment ground provisions. It is not a universal ground bar, and it mounts to the A-Series enclosure without field modification because the mounting matches that series. For a different panel line, use the ground kit that manufacturer lists for that enclosure.
4) Is the EGS12 an isolated ground kit or a standard bonded equipment ground?
It is supplied as a standard isolated/insulated equipment ground. The bar is insulated from the panelboard enclosure, which is what an isolated ground circuit requires when you are feeding sensitive electronic loads and need the ground path carried back separately rather than bonded at the can. If your job calls for a plain bonded equipment ground bar, this is the wrong part.
5) Can I add the EGS12 to an A-Series panelboard already installed in the field?
Yes. The kit is used both in new panelboard assemblies and in retrofits or replacement ground kits on existing A-Series panels. Because it is the factory accessory for that series, the ground provisions line up with the panel interior and no drilling or bracket fabrication is needed. Order one kit per 12 branch positions you need to land.
6) Can I land aluminum and copper grounds on the same ABB EGS12 bar?
The bar is rated for both metals, copper at 14-8 and 14-4 and aluminum at 12-8 and 6-4, so a mixed-conductor panel is within the kit's listed range. Note the aluminum ranges are narrower on the small ports: 12 AWG is the smallest aluminum the bar takes, versus 14 AWG in copper.
7) What exactly is the part number I order for the ABB A-Series ground kit?
The manufacturer part number is EGS12, an ABB A-Series isolated/insulated equipment ground kit packaged one per unit. The 12 in the designation reflects the 12 branch positions each kit covers.
