2.
Prepare and connect grounding conductors to the ground bus:
a.
Construct an equipment-grounding conductor long enough to
extend from the ground bus to an enclosure wall. Use 8 AWG
stranded wire or equivalent tinned braided cable copper wire
(the exact AWG should be in the grounding documentation from
the system designer) and ring terminals.
b.
Construct a grounding-electrode conductor long enough to
extend from the bus to your grounding electrode system (earth
ground potential). Use 8 AWG copper wire (the exact AWG
should be in the grounding documentation from the system
designer) and ring terminals.
c.
Connect the loose equipment-grounding conductors from step 1
and the two new conductors to the ground bus as shown below.
You can connect the conductors to the bus in any order.

3.
Connect the equipment-grounding conductor and
grounding-electrode conductor.
a.
Connect the equipment-grounding conductor to an enclosure
wall, as shown below.
b.
Scrape paint and other non-conductive finishes from both sides
of the enclosure wall, at the point where the grounding
conductor will attach. Be sure to scrape clear an area at least the
size of the ring terminal to be used.
