must be used for system grounding).
a. For a single-column system, connect a #6 AWG wire from the
ground source in the service panel to a ground lug on the pedestal.
b. For a multiple-column system, connect a #6 AWG wire from the
ground source in the service panel to a ground lug on the closest
column. Daisy-chain #6 AWG ground wires from one pedestal to the
next as illustrated in Figure 29, connecting all of the columns
together. You can also run a #6 AWG wire from the ground source to
each column individually. If the columns are not bolted together,
physically separated groups of columns should be grounded
individually as shown in Figure 27 on
