    That contractors know what they're doing.
    I can build anything you want if you draw a picture of it on the back of a big enough check.

    There's no substitute for hard work....but that doesn't mean I'm going to give up trying to find one.

    As a more generalized issue, I'd say it's a tie between NOT READING the code and ASSuming they know what it says / means (see "Charlie's Rule" thread in Campfire chat), or people reading it and not understanding the difference between "minimum" and "maximum" or ASSuming either one is "must be".

    What? I'd ask the inspector if he'd want to be the one to change out the fuses on a line side interconnected system. I'll stand far away and call 911.

    Because they are looking at it like the PV system is feeding to the panel (like it's usually drawn). Being an electrician I always plan check it backwards from the service to the panels. I just heard someone say that an inspector made him change it the other day, in another jurisdiction of course.

    Not making sure your brain is engaged before putting mouth in gear.
