Mr. Inspector

The field marking language of the 2014 NEC 110.24 states, “Service equipment in other than dwelling units shall be legibly marked in the field with the maximum available fault current. The field marking(s) shall include the date the fault current calculation was performed and be of sufficient durability to withstand the environment involved”
I have yet do an commercial service inspection where they had the max. Available Fault Current marked when I get there since I was an electrical inspector for almost 20 years. They always say no one ever required this before. This time I believe them because I never saw an existing service that had the Available Fault Current label.
Also it seems to be asking to much but their is no exception for any services not to have the Available Fault Current marked, like a small 100 amp 1 phase service for a sign or traffic light.
Sometimes the power company is sitting there waiting for me to approve the inspection for a change out and I feel pressured to pass the inspection without the Available Fault Current label.
How do other inspectors handle this?
