2. TRANSFORMER DISCONNECTING MEANS:
Sheet E-1 (Line Diagram – Transformer Disconnect). The transformer does not have disconnecting means. NEC Section 450.14 requires that transformers shall have a disconnecting means located either in sight of the transformer or in remote locations. Where located in the remote location, the disconnecting means shall be lockable and the locations shall be field marked on the transformer. Please address.
3. TRANSFORMERS MOUNTING (STRUCTURAL REVIEW)
Sheet E-1 (Power Line Diagram – New Transformers). Provide structural, seismic and wind load calculations as applicable, plus fastening details for the transformer include engineers stamp and signature, for structural review on a deferred submittal basis. Refer to Anchorage Administrative Code AAC 23.10.104.8.1. Please address.

5. NEC DEMAND LOAD ON PANEL SCHEDULE:
Sheet E-1 (All Panel Schedules - NEC Calculated Demand Load). There is no NEC demand load on any of the panel schedules. Provide on the plans the NEC demand load on every panel schedule. For example the connected load on panel DP2 is 779 amps that feeds from the 400 amp breaker. Refer to Anchorage Administrative Code AAC 23.10.104.8
6. PANEL AND TRASFORMER OVERCURRENT PROTECTION:
Sheet E-1 (Partial Line Diagram - Overcurrent Protection). Provide the over current protection for panels H13 and H14 and for the new transformer overcurrent protection on the secondary side..
