I hope you guys can help me. I putting on a presentation for about 50 inspeectors and I need to know the different places in the codes where we would be required to install signage. This could cover any codes that the electrician may be involved in the installation. Also sign wording would be helpful. Thank you in advance.

Have you got the handbook CD? Do a search on "sign". I got about 50 hits, some I didn't know about.

I should have been more specific. I was looking for places where you need signage. Like when you have Service equipment in two locations, or when you have two different grounded conductors from different systems in the same raceway etc.

George, that is what I am talking about. Search on "sign" and you will see a bunch you don't think of.
430.74, 430.113, 490.21, 490.22, 490.44, 513.7, 513.10, 514.11, 518.3, 540.11, 555.13, 620.3 <my mouse finger got tired> ... stuff like that. I didn't see the arc fault sign mentioned so I am sure another search word (like "signs" would find others.
If I had to summarize you need signs for GFCIs, flash hazards, backfed switches, multiple power sources or feeds (utility, generator or "alternate energy" sources), emergency systems, high voltage, various hazmat signs in classified locations, overhead cable warnings (waterways) and cable tray limitations but I am sure I am missing some.
The CD search engine is a good tool to find more. You can put together quite an eye opening show if you tracked them all down and that is just the NEC. Plug in the other NFPA documents, OSHA and state/local rules you might have to have 2 classes. ;-)

Thanks gfretwell, I guess my second post should have been directed at the comments that directed me to Article 600. I will take your advice and hopefully have enough material for a 2 hour program. I'll take some pictures, quote some code, use PowerPoint and with the inspectors and audience participation, I'm sure I'll be fine. I was hoping someone knew where the information is on labeling the door to Electrical room. Any code that would say that?

Like 110.34(C) Locked Rooms or Enclosures. The entrances to all buildings, rooms, or enclosures containing exposed live parts or exposed conductors operating at over 600 volts, nominal, shall be kept locked unless such entrances are under the observation of a qualified person at all times.
Where the voltage exceeds 600 volts, nominal, permanent and conspicuous warning signs shall be provided, reading as follows:
DANGER — HIGH VOLTAGE — KEEP OUT

110.16 is always good for discussion/argument.
