Eaton 6591C30G03 – Frequently Asked Questions

1) Will this Eaton handle lock kit fit my breaker, or do I need to check the frame first?
Check the frame letter before ordering. This Eaton padlockable handle lock adapter kit is built for Frame J-K molded case breakers only, and within that it is called out for type NB, HNB, NC and HNC breakers. If the breaker in your panel is a different frame size or a different type designation, this kit will not mount to it.
2) Does this Eaton adapter kit let me padlock a breaker in the off position for lockout/tagout?
That is exactly what it does. The kit adds a padlockable handle lock to a Frame J-K molded case breaker so the handle can be secured with a padlock for lockout/tagout work. It is a mechanical handle-locking accessory, so you supply your own padlock.
3) Is the Eaton Frame J-K padlockable handle lock UL Listed for use in a hospital or school panel?
The kit is UL Listed, which is the listing most facility electrical specs call for on breaker accessories. It is used in industrial panels, commercial distribution, healthcare and education facilities, and data centers. For any additional agency compliance beyond the UL listing, Eaton is the source on that.
4) What is the difference between Eaton 6591C30G03 and 6591C30G04?
Both are Frame J-K handle lock adapter kits under the 6591C30G family. The G03 is the padlockable version and the G04 is the handle lock version. Order by the exact suffix that matches the arrangement your panel needs, since the two part numbers are not interchangeable on paper even though they share the same frame coverage.
5) Can this handle lock kit be added to a breaker already installed in a panel, or does it have to be factory installed?
It ships as a complete adapter kit intended for field installation onto a compatible Eaton breaker frame, so an electrician can add it to a breaker that is already in service. Kill and isolate the panel before working on it.
6) I am standardizing lockout hardware across a plant. Can I use one Eaton kit for every breaker?
Not with this one. This kit covers Frame J-K breakers in the NB, HNB, NC and HNC types only, so it standardizes across that slice of your gear. Breakers in other frame sizes need the handle lock kit matched to their own frame. Inventory by frame letter rather than by panel.
7) Does the Eaton 6591C30G kit include the padlock?
No. It is a handle lock adapter kit, not a lockout set. The kit provides the padlockable handle lock mechanism for the Frame J-K breaker; the padlock and any tag come from your own lockout/tagout program.
