Joe, that is an excellent link, and bears detailed cover-to-cover study by "both camps." FIPS PUB 94 will always be a classic on perils of non-code grounding practices. It is a bit dated—for things have gotten a little better in meshing the NEC with so-called ‘technical’ / ’quiet’ / ’instrument’ / ’data-grade’ / ’isolated’ / 'flower-bed' / 'parking-lot' / 'just-plain-deadly’ grounding practices. One of the authors—Warren Lewis—will always be a hero in my book. I remember him giving a presentation at an IEEE petrochem conference about this, and he got an uncharacteristically spirited standing ovation at its conclusion.
He is a very level-headed engineer, and his message was long overdue. Believe me—he struck a deep nerve at the time. The paper served to open up a not-always-pleasant but eventually healthy dialog between tool-belt-packin’ tradesmen and computer geeks—and their seniors.
