If mounting in a metal rack, bond each piece to the rack and then home runs
from each rack to the bus bar.
Commercial communication site practice is to have a "halo" -
large-diameter wire or bus bar - all around the walls and tie each rack,
stand-alone box, conduit, cable ladder, etc. to the "halo". This is
then connected to a similar grounding system buried around the perimeter
of the building tied to ground rods per code. Sounds tedious but that's
what keeps the facility safe.
With thanks to my late colleague, Tom Croda, the recognized national
expert in the field of comm site power and grounding, who came to work
for my firm after retiring from Sprint and proceeded to teach us the
right way to do those things.
