YES, what Ghurd said,
Don't PO the guy. The best bet is always be nice and play a little stupid. Offer nothing, just listen.
In my dealings with building inspectors I am often faced with this kind of stuff. Someone tells me I have to do something, I say "wow, no other way?" Often they will say no, then I just look at them. Don't say anything. The average person will become very uncomfortable and start mumbling, "well you could do this or maybe we don't need that", I just nod and listen, offering nothing and often he resolves the whole thing himself with nothing changing.
If that doesn't do it then I often overwhelm them with info. And ask for more info that they don't have a clue about.
Gee, the code your talking about is for 110 and 220 volt AC residential wiring but I'm talking low voltage DC. Does that mean an inspector needs to come out before I can jump start one car with the battery from another one? No? Whats the difference?
Yes, play nice, never get combative. Public servants often love that. Don't offer info, and get things in writing. And the best way to get things in writing is to contact them that way and never talk to them in person or on the phone. Good Luck.
