290 OVERHEAD POINT OF ATTACHMENT
290.1 For new construction the Customer will provide and maintain a safe and substantial support on the building or structure to which the Company's service drop is to be attached. The Company will furnish to the Customer at the Company's storeroom office the attachment device that will be installed by the Customer.
290.2 The existing attachment device may not be suitable for terminating the service drop on a building to be rewired. At Company request, the Customer at their sole expense will provide, install, and maintain a safe and substantial support on which the Customer will install the new attachment device supplied by the Company. Where the Company determines that a bolt is required through the wall of a building, the Customer, at their sole risk and expense, will install a bolt furnished by the Company.
290.3 The attachment device shall be located such that personnel will not have to stand on a roof to install the service drop. It must be workable from a ladder set on the ground. It shall not be installed on a fire wall, parapet wall, chimney, belt of stone, brick or other material, a soldier course, an outside verge board, an inside verge board, the upper three layers of brick, the fascia covering end of rafters, the end grain of any wood member, siding between studs or any similar type construction, unless satisfactory additional support is provided.
290.4 The attachment device will be located so that service drops and drip loops have a minimum of 3 feet* clearance from windows designed to open, doors, porches, balconies, fire escapes or similar building openings. (* Exception: Conductors run above the top level of a window shall be permitted to be less than the 3 feet requirement.)
290.5 The point of attachment should be 12 feet above final grade or higher due to service drop and drip loop clearances. In no case shall this clearance be less than 10 feet. NEC Article 230.
290.6 See Section 270 for service drop and drip loop clearances. Consult the NESC for service voltages in excess of 300 volts.
290.7 Where a building is not of sufficient height to provide the required service drop clearances, the Customer shall provide a suitable support of sufficient height. The support shall be a pipe mast or steel member, of sufficient length and strength, bolted to the building, or other structure and approved by the Company. Consult the Company for tension weight information. Only power service-drop conductors shall be permitted to be attached to a service mast. NEC Article 230-28.
290.8 The maximum height of a point of attachment shall be 22 feet unless a higher point is specified in writing by the Company.
