Original Version
Rule 49.4-C7a
49.4-C7a) Supply: The minimum sizes shall apply
only where the span does not exceed 150 feet. The minimum for supply lines
of like voltage and grade shall apply when the service drop is in excess
of 150 feet. Supply service drops of 0-750 volts shall, in all cases, have
a weather-resistant covering equivalent to standard double braid weatherproofing.
NOTE-Resolution No. 756 effective May 29, 1951 authorized the use of multiple
conductor service drop cable with a bare neutral conductor for service drops
of 0-750 volts provided that the attachment of such cable at the pole and
building ends shall be by means of an insulator.
