Hi Guys,
Thanks for the explanation. I've neglected to mention that the ground wire is also connected to the ground of a three prong plug. So the ground runs from various electrical components, to the painted housing as well as the plug going to the wall outlet. I know some three pronged outlets are not truly grounded, but the ohmmeter indicates that the ground is active (at least according to my boss).
The issue of grounding to a painted housing has come up before. That's why we checked the rack with the ohmmeter. However, the results would indicate that the painted metal does in fact work.
Ok, here is another question: should I be concerned about mixed metal on the rack? So, the rack is stainless steel, but there are several aluminum items with stainless steel parts (some of which are wired) sitting on the rack. There is a small resistance being picked up from the stainless steel parts of these items. It's barely measurable, but seems to be real. What does this mean?
