Existing Low Voltage Switchgear One-Line Modifications

About this detail

This one-line diagram details modifications to existing low voltage switchgear panels DP73CA and DP73CB located within the existing electrical room. Feeder and control connections route from distribution switchgear to various motor control centers and panels, including MCC72U1, MCC72U2, MCC73T4, PNL73DC, and PLC 70 I/O drop 1. Specific cable and conduit schedules are provided for each run, detailing conductor sizes such as 500 KCMIL, #4/0 ground, #14, and #12 conductors alongside designated conduit diameters. Existing cables are also mapped to designated destinations like MMM Panel A.
