| 04/28/2008 | LINDA BUCZYNSKI | ELECTRICAL-COMMERCIAL | REVIEW | Passed | T08EL00356 4/28/08 1. See comments by Ray Majuta, 3/13/08, as pasted below. Electrical comments; Drawing has been denied for the following items. 1.Under load calculations the following statement is made. "recordings taken between June 28 and july 26.2005 indicate a maximum load of 680 a on the existing 600a service. The new service is sized at 800a." This is an unreliable and inconclusive method of determining the load. There have been no permits taken out in the past under this address to indicate an increase in capacity for the service,I presume the increase has been caused by additional increase on the load side. Provide calculations for the feeders being connected to the new service. 2. Under the box titled "Existing Feeder Sizes" the ampacities for conductors have the over-current devices set too high, for example----- # 2 AL GOOD AT 90AMPS OC DEVICE 100A # 1/0 AL GOOD AT 120AMPS OC DEVICE 175A # 2/0 AL GOOD AT 135AMPS OC DEVICE 200A # 3/0 AL GOOD AT 155AMPS OC DEVICE 225A # 4/0 AL GOOD AT 180AMPS OC DEVICE 250A. #3. The 2/0 cu grounding electrode conductor appears too small for the 800 amp service. Ray T Majuta Development Service Department Electrical Plan Exam 520-837-4988 Ray.Majuta@tucsonaz.gov #3.
