Follow these procedures in sequence.
Temporary Grounding Connection/Removal Procedures
Select a ground electrode using either an established ground at the structure or a
temporarily driven ground rod. The selection should minimize impedance and not
introduce a hazardous potential difference.
Test the de-energized line/equipment for voltage by an approved tester, verified
immediately before and after use as to its good working condition.
Visually inspect ground equipment. Check mechanical connections for tightness. Clean
clamp jaws and conductor surfaces. Clean not earlier than 5 minutes before connection
using a wire brush attached to a hot-line tool. Use of self-cleaning equipment is also
The ground end clamp of each grounding cable should always be the first connection made
and the last to be removed. Hot sticks will be used if the grounded system and worker are
at different potentials.
The conductor-end clamps of each grounding cable will always be connected last and
removed first by hot sticks. Apply to the nearest conductor first and proceed outward
and/or upward until all phases have been connected. Remove in reverse order. The
practice of holding the cable near the base of the hot stick to lighten the load on the head of
the stick is strictly prohibited. Instead, a co-worker should assist in installing heavy cables
by holding the cable with another hot stick, or by using a "shepherd hook" with a pulley and
a nonconductive rope to hoist the grounding cable into position.
5.3.3 Placement of Grounds. Grounds will be installed as close as possible to
the work. Temporary grounding connection/removal procedures will be in accordance
with Table 21.
126.96.36.199 Approach Distances
Never approach closer than working distances given in Table 11 until after
the line/equipment has been isolated, de-energized, tested, and properly
grounded. Afterwards, avoid coming closer than 3 meters (10 feet) to
minimize the hazard from step and touch potentials. This minimizes step
and touch potential differences.
188.8.131.52 Potential Differences. Such potential differences occur from items such
as down guys, ground rods, maintenance vehicles, and structure legs or ground wires
