Which means that the inspection by the Fire Marshall does not worry about the workmanship or compliance either, I guess.
Very true, I have seen AHJ's not even open the panel. Some simply check that all the devices work on DC power and that's it. However I have been showing AHJ's our work and we have built a great reputation in many towns and now they expect other panels and systems to be more thorough. Here is a great list of common codes that I give to all AHJ's.
