TABLE V-1
TABLE V-2
NOTE: Table V-1 - 1 For 345-362kv, 500-552kvb and 700-765kv, the minimum working distance
and the minimum clear hot stick distance may be reduced provided that such distances
are not less than the shortest distance between the energized part and a grounded
surface.
NOTE: Table V-2 - 1 For 345-362kv, 500-552kv and 700-765kv, the minimum clearance distance
may be reduced provided the distances are not made less than the shortest distance
between the energized part and a grounded surface.
OSHA SUBPART CC
Depending on the work being performed operation near power lines must follow OSHA 1926.1408 and
1409. This includes maintaining at least 20 foot (6.1m) clearance up to 50 feet (15.2m) depending on the
voltage. All personnel must be trained of the hazards when working near or on power lines.
