What the shared parts are
- HV switchgear, GIS, breakers, protection relays — The high-voltage switching, protection, and fault-isolation gear between the substation transformers and the campus's medium-voltage distribution, including gas-insulated (GIS) designs for compact sites.
- MV switchgear, E-houses, power skids — Medium-voltage switchgear packaged into pre-fabricated electrical houses (E-houses) or skids that distribute power across a campus and can be factory-built and shipped as modules.
- MV/LV transformers — Step-down transformers that take medium-voltage distribution down to the low voltage used inside a building, available in pad-mount (outdoor, oil-filled) and dry-type or cast-resin (indoor) designs.
- LV switchgear, switchboards, panelboards — Low-voltage electrical distribution equipment — switchgear, switchboards, and panelboards — that receives power from MV/LV transformers and distributes it onward to busway, PDUs, and building loads.

Questions
- Do ABB and Eaton compete?
- In this catalog they are both placed on 11 of the same parts, across 2 layers: HV switchgear, GIS, breakers, protection relays, MV switchgear, E-houses, power skids, MV/LV transformers, LV switchgear, switchboards, panelboards and 7 more. Sharing a part does not mean selling the same product to the same buyer, so read each row's product note.
- Which has more placements, ABB or Eaton?
- ABB has 16 placements and Eaton has 21. Placement counts reflect how thoroughly each company has been catalogued as well as its real breadth, so they are not a ranking.
