681 terminating to the ground connector in the pole shaft or parapet bracket. The other end of this conduit, which terminates in a ju nction box, shall be bonded to the junction box frame and to an insulated ground conductor which shall be installed in the same conduit as the lighting circuit conductors. This ground conductor shall be continuous across each bridge, and it shall be attach ed to the ground rod in the junction box or lighting support adjacent to each end of a bridge.
662.13.5 Service and Control Stations: Grounding of all service and control stations shall
be accomplished by means of a ground connector installed in the ser vice cabinets where shown on the Plans and bonding all conduit ground bushings, metal casing of equipment, and neutral conductors by means of individual # 4 conductors, as elsewhere specified to the above mentioned ground connector. The other ends of these conduits shall be bonded together and connected to the ground rod in the adjacent concrete junction boxes.
662.14 Testing :
The Contractor is advised that before proceeding with any work under this Contract, the Contractor shall conduct the necessary continuity and insulation tests to establish the integrity of cable runs already in place. The Contractor shall report any cable fault found to the Engineer. In case any fault is located while contract work is in progre ss, and which has not been reported by the Contractor as prescribed, then the Contractor shall be responsible for the correction of any such fault without any extra compensation. Continuity and insulation tests shall also be performed in a manner satisfac tory to the Engineer on cable runs to be placed under this contract. The Contractor shall be responsible for the correction of any fault discovered. With all equipment connected to the wiring system, a functional test shall be performed by the Contractor in the presence of the Engineer to demonstrate that the system as a whole and all parts thereof function as specified or intended. Any defective materials or faulty or improper installation shall be permanently corrected by repairs or replacements to be ma de by the Contractor to the satisfaction of the Engineer at no additional cost. Lighting circuits shall then be subjected to such other tests as may be required, including additional insulation resistance testing as detailed in 662.9, and shall be the res ponsibility of the Contractor to perform these tests in the presence of the Engineer or authorized representative. All tests shall be performed at the expense of the Contractor. After the installation is completed, the Contractor shall conduct a continuou s 24-hour operating test for approval. In addition, final acceptance of an installation will not occur until 30 days of operation termed satisfactory by the Engineer. During the 30 days of operation, the Contractor shall be responsible for repairing or replacing any defective equipment within 24 hours after being notified by the Engineer. After any malfunctioning equipment has been repaired or replaced, the 30 day test shall begin anew. The Contractor shall inspect and certify to the replacement of all da maged traffic signal loop conductors and to the proper functioning of the traffic signal, and that the junction boxes within the project limits comply with section 660.15. The inspection shall be performed before project completion and after all the work has been completed in the area of the traffic signal system and related components. The Electrical Inspection shall be paid as item 662015 -*, Electrical Test, per Lump Sum. 682 662.15 -METHOD OF MEASUREMENT :
