Electrical One-Line Diagram Protection and Distribution

About this detail

A 2000A, 480V, 3-phase, 3-wire, 60Hz bus with a 65KAIC rating continues from sheet E-00-635 to distribute power across multiple circuits. The system feeds motor control centers with associated metal oxide varistors and surge protective devices via specified conduit and conductor sizes such as 3#12 and #12G in 3/4-inch conduits. A 45kVA transformer steps down voltage from 480V to 208/120V to supply downstream panelboards.
