Hi.
Installing a substantial amount of professional equipment in half a dozen racks, there is copper grounding buss bars among the items.
I thought I had it clear, but cannot discern its proper use. Please help.
The bars are BB-40 : https://www.avalive.com/Middle-Atlantic/BB-40/15627/productDetail.php
And I installed them exactly as per their enclosed instructions. The part I do not get is they are isolated from the metal rack by nylon washers. The link above shows the insulating plate and shoulder washers for the fastening hardware.
The energy is the standard 120VAC phase, neutral and ground.
The floor is metal; the room walls are a Faraday cage, in a concrete building; grounding rods are hooked to the room floor, roof and walls.
What is the usage of such buss bars ? All equipment has its proper 3-prong plugs to the outlet strips; all cabinets are metal, attached to the grounded metal racks.
