That's very interesting Al. There was a poster here who would isolate and meter N to G for any 'loop' effect. I have read about the power quality people who will monitor the guass in industry, and weed out/alter the offending circuitry. There was also a poster over in Mike H's forum who apparently caused quite a flap over a children's playground built under some High-V lines.
The very way i wire daily is in question by some of these savey individuals, i always have an ear open for them.
