You can't be talking about the code inspector so I am guessing someone in your IT department still has a leisure suit in the closet. It was determined decades ago that IG did nothing to make computers work better and compromised surge protection. You want as much bonded together as you can get with as short a path as you can get. The IG made the ground too far away to do much in a serious transient event like a nearby lightning strike.
Good point. Of course that woudl be true whether the "keeper" is paper, plastic, or metal.
I was around for that, we were using braided ground straps on every floor post and ferrites on anything that wasn't grounded. The thought was very short ground paths and ferrites to slow down the signal long enough to slow down the transient in the signal lines until it was shunted out ... or some such thing. Whatever it did work for esd and common mode transients. When we finally analysed the "noise" we identified the enemy and it was us! The noise was not external at all, it was coming from 100-200a switch mode power supplies in the mainframes. The next generation of machines (30xx and 43xx) had quieter power supplies and all of that stuff went away (circa 1980 or so).
A few years later we took that "short ground path" stuff out of the glass house and into the hinterlands to protect all of those little machines you see in "retail" from lightning (banks, hotels, restaurants and stores)
We had people plugging their terminals in regular outlets and using the IG for the operator's space heater. We were telling people
The clip bonds the screw to the device yoke and the threads bond it to the box ... or so they say.
I"ll pay attention next time i'm at th estore or in the wall.
That is true on both counts.
It ensures continuity for the grounding system when installed in a metal handy box.
