Not criticizing Electricians or the professon but there are those that just follow codes and those that understand the theory. Never read the full NEC but some of the rules don't make sense.
An interesting exercise for those in an urban or suburban location is to take a clamp-on ampmeter and measure currents on water pipe entrances, ground lines off power poles, phone grounds, and anything else you can find. You can totally disconnect your house by dumping the two hots and still find potential differences and currents. BIG difference in rural areas with large distances between sources and many fewer problems.
Someone commented about degrees....from what I've observed in the industry, an engineer is degreed. we all know the definitions:
BS -- Bull ****
MS -- More ****
PhD -- Piled Higher and Deeper.
I'm full of Bull from the place voted the ugliest campus in the U.S. on a Princeton survey per the national news in the last couple days.
I needed some humor today.
