All references are to the 2005 NEC and amendments. 1.Provide fault current calculations beginning at MSD on through to electrical equipment. 2. Provide current calculations at following points, a Inverter AC terminals b Inverter DC terminals c 4 pole and 3 pole disconnects. 3. Regarding "Notes" Table Sheet 2.0, Tag #1 conductors used in cable tray to be identified for use per 392.3 NEC, Tag #2 , 48 conductors type USE-2 in 3" LFMC ----- Tables in Chapter 9 of the NEC do not list this conductor use for being installed in LFMC, also the current adjustment factors are to be applied per 310-15. Tag #3 through 7 states schedule 40 RNC to be used, this type of conduit is not allowed to be used unless physically protected, how will this be accomplished ? 4. Sheet E4.0, concerning the Combiner Boxes, are these listed for their use, provide information sheet on these. 5. How have the conductors to be used outdoors been adjusted for their ampacities according to temperature per NEC 310.16 ? 6. Have the voltage correction factors for modules been addressed according to NEC 690.7 ? 7. How has NEC 690.8 been addressed, concerning circuit sizing and current , A and B ? 8. According to the Inverter information sheet, the isolation transformer is provided with the 480 v Inverter, since no futher information is provided ,provide a brief description of it"s operation . 9. Sheet E 8.1, Grounding Layout, indicate on this sheet points where the GEC is to connect to the Equipment Ground only. 10. The 16+00 amp MDS being 480 v shows GFI protection at main. Note on plan that a written record of Performance Test per NEC 230.95, is to be made available for Inspector. 11. Provide notation on plan for Warning Signs to be placed per NEC 690, for the following sections,690.14C.2, 690.17, 690.53 , 690.53.B.
