Electrical Single Line Diagram
The red lines are the electrical wires spread over the plan. The electricity would first come into the building at 480V, 3 phase. Then it would reach a 50KVA, 480V to 208/120V transformer. The 600 A, 208/120V panel distributes wires to different location of the floor. Just in case there is a power cut, the 45W, 208/120V generator would provide electricity for the emergency. Detailed calculation is shown in the next section: Electrical Component Sizes.
