The schematic outlines the main electrical room level one distribution network originating from a 3000A main LAWA board. Power feeds descend to a 1200A spare panelboard, an 800A NPV board, an 800A NPA board, a 400A HLM3 board, and an 800A DPBF1 board. Additional lines extend to a 1600A board for T4.5 connections in the level 1 headhouse, feeding existing 1200A NSWBP1 and 225A NDBP3 boards located in the T4.5 core. A separate 1200A main IT systems board is also integrated into the layout.
