Contractor shall verify and coordinate exact location of equipment to be furnished by others prior to rough-in. O. Contractor shall be responsible for replacing equipment which is damage due to incorrect field wiring provided under this section or factory wiring in equipment provided under this division. P. Contractors shall visit site prior to bid and verify that conditions are as indicated. Contractor shall include in his bid, costs required to make his work meet existing conditions. Q. Proposed substitutions of electrical equipment or request for "or equal" or approved equal" listing shall be submitted to architect not less than ten (10) working days prior to bid. Refer to specifications for additional information. R. Wire termination provisions for panelboards, circuit breakers, safety switches and all other electrical apparatus shall be listed as suitable for 75 degree C. Page 2 of 6

3 S. Systems shall be complete, operable and ready for continuous operations. Lights, switches, receptacles, motors, etc., shall be connected and operable. T. Electrical equipment shall be located to maintain clear and level clearances outlined in NEC Panelboards, switchboards, transformers, disconnects, switches, breakers, etc. shall be located to comply with NEC (a). Where the clearances outlined in NEC cannot be obtained, the Contractor shall notify the engineer prior to performing any rough-in. U. Maintain separation between telecommunication conduits and electrical feeders, electronic ballasts, transformers, etc. to minimize electromagnetic compatibility issues. V. Telecommunications horizontal cabling conduit runs that exceed 100 feet shall be provided with junction boxes for every 100 feet or fraction thereof in excess of 100 feet. W. Contractor shall coordinate horizontal telecommunications cabling routing to ensure TIA/EIA distance standards are not exceeded; in effect, 90 meters/295 feet from TR termination to outlet termination. X. Contractor shall not exceed two (2) 90 degree elbows in telecommunications conduit runs. If more than two (2) 90 degree turns are required, pullboxes shall be provided for every 180 degrees of bend. Y. Contractor shall review telecommunications and other low voltage drawings and provide all raceway, conduit, cable tray, etc. as required. Ladder tray within the Telecommunications Room (TR)shall be furnished and installed by the low voltage cabling Contractor. 1.5 ELECTRICAL SUBMITTALS A.
