The two point, hand-cranked megger that I'm used to (ex-Navy) were used to determine high resistivity, not low resistivity. That's why the question.
House was turned over to me by the builder on Feb 28th, 2005. Builder started house in November, 2004.
I started the detached garage in late November, 2004. Finished in early January, 2005.
Which brings the question, if the most current NEC code is enforced by the local municipality, is the start date or the finish date of the structure that bears importance to meet local code? I know its unlikely in my case as the municipality has to pass that most current NEC code into their current code before the municipality's inspector can enforce it.
