MCCs are most widely used in the utilities, manufacturing, industrial, and large commercial industries that operate machinery and motors. MCCs offer enormous flexibility across differing industries and are suitable for many applications, such as: utilities, communications, oil, gas, chemical, pulp, paper, water, waste, mining, metals, industrial production, and mass-production manufacturing. MCCs are used to house various power distribution equipment and controls such as: main distribution panels (MDPs), main circuit breakers (MCBs), protective relaying, transformers, load centers, panelboards, etc.
Protection and Controls (P&C) engineering and design is extremely important in power grid protection and coordination especially with the use of intelligent electronic devices (IEDs). Proper P&C designs and coordination with protective relaying and IEDs is an essential part of electrical power engineering for protecting large expensive power equipment such as: generators, transformers, transmission lines (TLs), power circuit breakers, electrical bus, etc.
