Eaton 17-21109 – Frequently Asked Questions

1) Will the 17-21109 neutral base fit a non-Eaton panel like Square D or Siemens?
No. The 17-21109 is built to fit Eaton panelboards and load centers and to work with approved Eaton ground bar systems. Panel manufacturers use their own mounting geometry inside the can, so for a Square D or Siemens enclosure you want that manufacturer's own neutral or ground bar mounting hardware. Substituting across brands also puts you outside the panel's listing.
2) Is the Eaton 17-21109 a complete ground bar kit or do I need to order the bar separately?
You need the bar separately. The 17-21109 is the neutral base only, the supporting mounting component that a compatible Eaton ground bar kit attaches to. Order the matching Eaton ground bar assembly for your enclosure along with it, or you'll have a base with nothing to mount.
3) What part number should I give my supplier for the Eaton neutral ground bar mounting base?
Eaton 17-21109. That's the manufacturer part number, also shown as model 1721109 without the dash. Give the hyphenated form to an Eaton counter and they'll pull it.
4) Can I use this neutral base in a commercial panelboard, or is it a residential load center part?
Both. The 17-21109 is used in panelboard and load center grounding assemblies across commercial, industrial, and residential distribution equipment, on new construction as well as retrofit and panel upgrade work. What determines fit is that the enclosure is Eaton and the ground bar kit is a compatible Eaton assembly, not the occupancy type.
5) I'm adding a ground bar to an existing Eaton panel during a service upgrade. Is this the piece I'm missing?
If the bar has nowhere to land, yes. The 17-21109 is the neutral base that gives the ground bar a defined mounting position inside the enclosure. On an existing Eaton panel where the original base is damaged, missing, or the panel was never furnished with one, this is the component that restores a proper mounting point for the bar. Confirm the ground bar kit you're adding is an Eaton assembly for that enclosure.
6) Is the Eaton 17-21109 a genuine Eaton part or an aftermarket copy?
Genuine Eaton, supplied as Eaton part number 17-21109. That matters here because the base has to match the mounting provisions Eaton designed into the enclosure and the ground bar kit. An aftermarket lookalike that doesn't land correctly leaves the bar loose, and loose grounding hardware is the thing an inspector finds.
