| 09/10/2018 | DAN SANTA CRUZ | ELECTRICAL-COMMERCIAL | REVIEW | Reqs Change | Please address the electrical plan review comments from this 2nd plan review. Also provide a written response. Ref; Revised Plan Sheet E4.0. #1. Comment (a) was to include neutrals with the feeders for the new 400 amp service. NEC 250.24. The Keyed note #11 is incorrect. Per the revised drawing E4.0, the neutrals are not continuous to the utility supply source. Without these neutrals, Panel 'DP1' will not operate properly as a 3 phase 4- wire panel. Also there is no low impedance path for fault current back to the electrical supply source. Verify that Keyed note #9 is correct. Without grounded conductors (neutrals) installed with the secondary's, the AC system will not operate as designed. Please see NEC 250.2. #2. Comment (e) was to provide a fused disconnect to protect the derived transformer feeders to panel 'LP1A' . The fused disconnect should be on the secondary side of the transformer.NEC 240.15, 240.21, 450.14. Ref; 2012 IBC section 107.2.1, 2011 NEC City of Tucson Commercial Plan Review Requirements.
