About this detail

This electrical distribution diagram details a 480-volt, 3-phase, 3-wire, 2000-amp switchgear arrangement with distribution panels DP73AA and DP73AB connected via a 1600-amp bus duct. The system incorporates multiple feeder breakers with specified trip and frame ratings feeding equipment such as motor control centers, centrifugal units, variable frequency drives, and programmable logic controllers. Tie breakers with normal-open and normal-closed designations manage power routing across the bus sections.
