ABB General Duty Universal Hub Closing Cap

The ABB General Duty Hub Closing Cap is a practical load center accessory built to seal unused hub openings on electrical panel enclosures. Featuring a 3" base size, this closing cap is engineered for universal compatibility, meaning it can be used across all ABB load center panels regardless of configuration rather than being limited to a single model. Electrical contractors and facility maintenance teams rely on closing caps like this one to keep panel enclosures properly sealed when a hub or knockout opening is not in use, supporting a clean, code-conscious installation and helping maintain the integrity of the enclosure. Each unit ships individually packaged, 1 EA, making it simple to stock as a spare or order in the exact quantity a job requires.

  • Simple Sealing Accessory: Functions as a closing cap to cover unused hub or knockout openings on the panel enclosure, helping keep the enclosure properly closed.
  • Convenient Packaging: Supplied 1 EA per unit for straightforward ordering, whether stocking spares or completing a single closure.

ABB TCCP – Frequently Asked Questions

1) What size opening does the ABB TCCP hub closing cap cover?
The TCCP closing cap is a 3 inch size, so it covers a 3 inch hub opening on an ABB load center enclosure. If the unused knockout in your panel is a smaller trade size, this cap is the wrong part for it.
2) Will the ABB closing cap fit any ABB load center, or do I need a model-specific part?
It is a universal fit accessory for ABB load center panels, so you do not need to match it to a particular panel model or configuration. For a maintenance crew that means one part number on the shelf instead of a cap per panel type.
3) What is a hub closing cap actually for on an electrical panel?
It seals an unused hub or knockout opening on a load center enclosure so the box stays closed. Panels come with more openings than most installs use, and leaving one open defeats the point of the enclosure. Contractors and facility teams use caps like the ABB TCCP on new buildouts, retrofits where a conduit run was removed, and routine panel service.
4) Can I use the ABB TCCP as a conduit fitting or reducer instead of a cap?
No. It is a dedicated closing cap, not a multi-purpose fitting, reducer, or hub. Its only job is closing a 3 inch hub opening. If you need to land conduit in that opening you want a hub or connector, not this part.
5) How many caps come in a package of the ABB TCCP?
Sold as 1 each, individually packaged. Order the exact count of openings you need to close rather than a bulk carton.
