The previous electrical plan review comments were not addressed. Original comments; For clarity, please provide complete electrical plans and scope in detail of the proposed electrical work. For example, the notes on the electrical plan call out to replace the existing 600 amp service disconnect with a ‘Service Entrance’ ….... Provide detailed information about the ‘Service Entrance’. Such as; (a) Secondary conduits, conductors quantity and types. (b) AIC ratings of electrical equipment. (c)Voltage, Phase, Amp rating of the ‘Service Entrance’, OCPD types and ratings. (d) Grounding detail. (e) New or existing panels and complete panel schedules if applicable. (f) Load calculations.(g) Is this a metered ‘Service Entrance’ Cabinet? Where is the utility meter located? If necessary, obtain the services of an experienced Electrical Engineer to perform design and load calculations necessary to provide evidence on the plans that the installation meets all the requirements of the 2017 NEC. Ref; 2018 IBC section 107.2, 2017 NEC, City of Tucson Commercial Plan Submittal Requirements. 1st comment. The line diagram is still confusing. . It appears per the diagram, that a single 600-amp 3 phase Main Service Disconnect with 600-amp fuses is utilized to feed 3 separate 200-amp 3 phase disconnects inside the building. How are 3 separate feeders (inside disconnects) going to terminate in a single 600-amp disconnect ? How are the 200-amp feeders protected ? The 600-amp fuses are over-sized per NEC art 240.4 and 310.15(B)(16). Please clarify. Ref; 2018 IBC section 107.2, 2017 NEC, City of Tucson Commercial Plan Submittal Requirements. |
