Original Version
Rule 54.6-B
54.6-B. Ground Wires
Ground wires shall have a conductivity and Mechanical strength
at least equal to that of No. 8 AWG medium-hard-drawn copper wire; they shall
not be installed on the top surfaces of crossarms; and they shall have clearances
of not less than 1 ½ inches from hardware in accordance with the provisions
of Rules 52.7-B and 52.7-C.
Ground wires attached to or run on the face, back or underside of wood crossarms
or on the surface of wood poles and structures shall be covered throughout
their poles and structures protective covering (see Rule 22.2), excepting
that ground wires of 0-750 volt circuits or equipment are not required to
be covered where installed on the underside of crossarms or the portions
of crossarms supporting 0-750 volt conductors.
Ground wires of common neutral systems are specially required to comply with
the provisions of Rules 59.3-C and 59.4 in addition to the provisions of
this Rule 54.6-B.
