Section 296-307-36609 - ConductorsThis section applies to branch circuit, feeder, and service conductors rated 600 volts, nominal, or less and run outdoors as open conductors.
(1) Conductors supported on poles must provide a horizontal climbing space of at least the following: (a) For power conductors below communication conductors, 30 inches.(b) For power conductors alone or above communication conductors: (i) 300 volts or less, 24 inches;(ii) More than 300 volts, 30 inches.(c) For communication conductors below power conductors with power conductors of: (i) 300 volts or less, 24 inches;(ii) More than 300 volts, 30 inches.(2) Open conductors must provide at least the following minimum clearances: (a) 10 feet, above finished grade, sidewalks, or from any platform or projection from which they might be reached;(b) 12 feet, over areas subject to vehicular traffic other than truck traffic;(c) 15 feet, over areas that are subject to truck traffic; except(d) 18 feet, over public streets, alleys, roads, and driveways.(3) Conductors must have a clearance of at least 3 feet from windows, doors, porches, fire escapes, or similar locations. Conductors run above the top level of a window are considered to be out of reach from that window and, therefore, do not have to be 3 feet away.(4) Conductors must have a clearance of at least 8 feet from the highest point of roofs they pass over. Exceptions: | (a)Where the voltage between conductors is 300 volts or less and the roof has a slope of at least 4 inches in 12, the clearance from the roofs must be at least 3 feet; or (b)Where the voltage between conductors is 300 volts or less, the conductors do not pass over more than 4 feet of the overhang portion of the roof, and they are terminated at a through-the-roof raceway or approved support, the clearance from the roofs must be at least 18 inches. |
(5) Lamps for outdoor lighting must be located below all live conductors, transformers, or other electric equipment, unless such equipment is controlled by a disconnecting means that can be locked in the open position or unless adequate clearances or other safeguards are provided for relamp-ing operations.Wash.
