My experience with the electrical inspectors is that they're fairly easy to deal with. If there's a problem they show you what it is, you correct it and they come back and reinspect and sign off on it. Its not rocket science to wire a house if you're reasonably mechanically inclined and do your research. But if you're not you are far safer to hire someone to come it and do it for you.
I've always done every repair on my home or cars or other equipment so I'm comfortable with pretty much working on anything. Education is the key as it is to most things in life.
