Electrical One Line Diagram for Motor Control Center and Distribution

About this detail

An electrical one-line diagram details a 2000A, 480V, 3PH, 3W, 60HZ, 65KAIC bus continuing from sheet E-00-625. The main bus distributes power through various circuit configurations, including branch circuits feeding motor control center units such as MCC73S2-23 through MCC73S2-33. Specific feeds incorporate conduit and conductor sizes like 3#12, #12G, 3/4 inch and 6#14, #14G, 3/4 inch, supplying local control stations, junction boxes, moisture sensors, and motor operated valves with designated 3P-20 and 3P-30 circuit breakers. Manufacturer cables and panel connections like PNL74764-9, PNL74764-12, and PNL74764-13 are indicated alongside drop connections and disconnect switches.
