Do you make sure that all circuits and circuit modifications are legibly identified as to their purpose or use on a circuit directory that is located on the face or inside of the panel door in the case of a panelboard, and at each switch on a switchboard? 408.4
Do you also make sure 110.22 is complied with as well?
In the lines of HotLine1's message, for a "minor" service type installation, I'll update the directory as to the new circuit(s) installed.
For remodels / T.I.s which result in nearly all circuits being altered, I'll print out a new, clean Directory (with a few extras - 1 blank, 1 with minimal info).
For new installs, definitely print out Directories.
At times, I'll also include a Panel Schedule for use in future load calculations, or to determine what's been designed to the circuitry at the time. All these items - of course, are custom created databases & spreadsheets - printed from my Home based Workstations.
As to labeling Equipment / Discos / etc., if not subject to weather or "abnormal" physical influences, I'll print out Panel / Circuit information on either 5163 label stock, or using the "Brother P-Touch" label maker. Where these labels will last 5 days max., I'll "carefully" print Panel / Circuit information using a Permanent Marker or "Paint Pen".

Earl: I work PT as an AHJ (2 days), and the Twp has a very diversified ethnic population.
Yes, I had a panel marked in chineese characters, and I requested English sub-titles from the owner/contractor.
I understand that english was not the 'first' language of the occupants, but I cannot read chineese either. Although this subject could be debated at the Board of Appeals, I choose the easy way out and 'requested' the sub-titles.

Thanks for the many replies: I will bet that NFPA would have a problem with an NEC Proposal that would accommodate the language issue in your areas, can you imagine?
Earl and John: I will be the third submitter if you submit a proposal for the 2008 NEC!
By the way I am in Biloxi, Mississippi at the NEC TCC (Technical Correlating Meeting) and they are reviewing the NEC Comments and Panels Actions --- some interesting issues and information I am absorbing.
