NEC 408.4 Requires every circuit to be legibly identified as to its clear, evident, and specific purpose or use.
Does the attached photo comply? If I can upload the photo.....

No photo...

Photos.
The ones I had were too big.

Tough question. I see the dilemma. I could take either side and come up with a compelling argument.
Of course the right answer is two directories, one in English and one in Chinese but I am not sure there is actual code "language" to support it.

That is both funny and thought provoking...

I agree with Greg. I would have no problem with a foreign language directory as long as an english directory is also provided.

Here are some better done photos.
Both sides are answered.
PLEASE PLEASE Let's not start putting language requirements in Code Proposals!

What was the original file sizes.
Maybe we can tweak the setting so you don't need to convert them.

As far as the question goes. I guess we need to know what was the real intent of the code.
Is it for the inspector or for the end user?

This is a good question...

Is the end user the current tenant or occupant?

Is the end user the owner of the building?

Is the code directory for users, contractors and maintenance, or code enforcement?

Very thought provoking...

The short answer is "all of the above".
In a multinational, multicultural world it is going to be hard to fulfill that with a single language. I am not sure how the code would, or even should, address that.

In the example above I am curious if the electrician was Asian or if this was unlabeled and the directory was filled out by the tenant later.

I would defer to the last and highlighted statement in 408.4, along with the explaination in the handbook and analysis and effect section of IAEI's Analysis of Changes, it should be clear to whomever is looking at the panel schedule what each circuit is, whether it be inspector, maintenance, code enforcement or contractors, in short, I agree with gfretwell, all the above, and if necessary a suplemental directory in another language other than that of the normal regional language could be added. just mho
