Table 7-8. Conductor Ground Location After Pulling
Ground at each structure next to intermediate deadends of the stringing
Ground at each structure where and while work (including clipping-in) is being
performed on or near the conductor.
Remove grounds as the last phase of finished aerial installation.
TEMPORARY GROUNDING OF AERIAL LINES. Ground by installing an
overhead distribution grounding set. The grounding set provides a parallel low-level
(milliohm) resistance path which limits the current flow through the worker to a very low
(safe) value (milliamperes) thus limiting the potential across the worker to a safe value.
flow through the worker under fault conditions. Avoid any ground connection which
could provide violent whipping from wind action. Double-point grounds are sometimes
utilized but single-point (equipotential) grounding is the preferred method. If double-
point grounding is necessary, install the temporary grounds at least one span away from
the work site because the grounding cables may violently move during a fault condition.
