Interconnection diagrams shall show for each piece of equipment all wiring <br /> between all devices, panels, cabinets, terminal boxes, control equipment, <br /> motor control centers and any other devices and equipment. An <br /> interconnection diagram shall be furnished for each electrical and <br /> instrumentation system, even if one was not shown explicitly on the Contract <br /> Drawings. Interconnection diagrams shall be prepared for all conduits listed in <br /> the Conduit and Wire Routing Schedule. Each interconnection diagram shall <br /> show the following as a minimum: <br /> a. All interconnection diagrams shall be prepared by a System Supplier <br /> under the supervision of or by a State of California Registered Electrical <br /> Engineer and shall bear that Engineer's professional stamp and <br /> signature for all Interconnection Drawings submitted for approval <br /> including as-builts and those used in the field installation. All deletions <br /> and additions of equipment, wire, and cables shall be clearly shown. <br /> Interconnects shall include list of all applicable reference Drawings, <br /> request for clarifications, field instructions, and change orders. <br /> b. 'The diagrams shall be utilized by the electrician during all phases of <br /> nstallation and connection of all conductors to ensure coordination of <br /> equipment interconnect. <br /> C. The diagrams shall show wiring as field labeled at the end of the project <br /> when as-builts are submitted. <br /> d. Each wire labeling code as actually installed shall be shown. The wiring <br /> labeling code for each end of the same wire must be identical. <br /> e. All devices and equipment labeling codes shall be shown. <br /> f. All Interconnection wires listed in the Conduit and Wire Routing <br /> Schedule for each conduit shall be shown only on one interconnect <br /> drawing. Interconnection diagrams shall be of the continuous line type <br /> with identified lines. Diagrams of the wireless or wire schedule type are <br /> not acceptable. Bundled wires shall be shown as a single line with the <br /> direction of entry/exit of individual wires clearly shown. <br /> q. All terminations points on the diagram shall be shown with the actual <br /> equipment identification terminal number or letter. This identification of <br /> terminations includes terminal blocks, junction boxes, all devices, <br /> computer 1/0 points, etc. <br /> July 2007 Division III-176 NEI Phase II Water and Sewer <br /> CIP Nos. 7468, 7589, 7590 <br />
