Decision Number 78516 GO 95 rule 84.4-D1

84.4-D1) Conductors Supported On Crossarms: The 15-inch minimum clearance from center line of pole specified for communication conductors supported on crossarms may be reduced under the following conditions:

For open wire toll and other open wire line conductors not used for exchange or local distribution, a clearance of not less than 9 inches from center line of pole may be used;

For open wire exchange or local distribution conductors which were originally installed as toll line conductors, a clearance of not less than 9 inches may be used provided such exchange conductors do not carry more than 160 volts and 50 watts and a clearance of not less than 15 inches from center line of pole shall be obtained when appreciable reconstruction of such lines is undertaken;

For open wire and local exchange and local distribution conductors in rural districts, the conductor clearance from center line of pole maybe not less than 9 inches provide voltage of such conductors is not more than 160 volts, power transmitted does not exceed 50 watts, the clearance of not less than 9 inches shall apply only to conductors supported on a crossarm in the pole top position and no conductors are supported below such crossarms except supply service drops of clearance crossarms. This provision for lines in rural districts is intended to permit the use of a related buck arm, in which the climbing space shall conform to the requirements of Rule 84.7-B ;

Cables or messengers may be attached to opposite sides of pole and have clearances less than 15 inches from center line of pole where placed 2 feet or more below the level of the lowest communication conductors supported on crossarms;

Cables or messengers may have clearances less than 15 inches from center line of pole where placed between crossarms or less than 2 feet below the level of the lowest commumcation conductor supported on crossarms provided, for climbing space purposes, such cables are placed on one side of pole only and any conductor (supported by a crossarm and on the opposite side of pole) which is within 36 inches vertical may from the level of the cable or messenger is not less than 24 inches (if an exchange conductor) or 18 inch (if a toll conductor) horizontally from the vertical plane of such cable or messenger. (See App. G, 84.)

For open wire toll and other open wire line conductors not used for exchange or local distribution, a clearance of not less than 9 inches from center line of pole may be used;
