It is probably packaged that way because of the UL Listing. All electrical products get tested, and if they pass, get listed by Underwriters Laboratories (or other approved agency) in order for them to sell to the public. They can only get listed in the fashion that they were tested in. An Eaton/Cutler Hammer panel is the same as a BR load center.
Hey Oli Even if the load center had the holes, they are not always where you want / need them;( I drilled my own holes in mine and put em' where I could use them easily and not crowded under the wiring. Here's the answer for the code enforcer: The Eaton grounding bars are UL Listed. The process of that evaluation would include any instructions that came with the listed product. The instructions in the bag tell you the spacing and size holes to drill. It meets code.
I had originally answered this question without having the information in front of me. However, now that I do it will accommodate up to a #4.
There is no amperage rating for a ground bar.
The dimensions of the box are 11x13.
