Rule 54.4-A2
54.4-A2) In Rural Districts, Conductors of 750-21,000 Volts:
a) Crossing Roads or Driveways: In rural districts
the minimum clearance of 25 feet specified in Table 1, Case 3 Column E may
be reduced to 22 feet above ground for conductors crossing or overhanging
traversable portions of public or private roads or driveways. This
modified minimum clearance of 22 feet shall in no case be reduced because
of temperature or loading at conditions less than the maximum loading or
temperature specified in Rules 43.1 and 43.2.
b) Above Agricultural Areas Along Roads: In rural
districts the minimum clearance of 25 feet specified in Table 1, Case 4 Column
E may be reduced to 18 feet above ground lines across areas capable of being
traversed by agricultural equipment and along roads where no part of the
line overhangs any traversable portion of a public or private roadway.
This modified minimum clearance of 18 feet shall in no case be reduced because
of temperature or loading at conditions less than maximum loadings or temperature
specified in Rules 43.1 and 43.2. Care should be exercised in using
this minimum clearance along roads, above or along ditches where mechanical
devices are used for maintenance, near trees in orchards, near trees or structures
which can be climbed and in other similar situations.
