A motor control center (MCC) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter, fuses or circuit breaker, and power disconnect. A motor control center can also include push buttons, indicator lights, variable-frequency drives, programmable logic controllers, and metering equipment. It may be combined with the electrical service entrance for the building.
Low Tension (LT), Motor Control Center (MCC), and Power Control Center (PCC) panels are essential components in electrical distribution systems. They help manage and control electrical power, ensure safe operation, and facilitate efficient distribution. Here’s a detailed overview of these panels:
General Considerations for All Panels:
- Safety: Ensure panels are designed with proper safety features, including clearances, interlocks, and protection devices.
- Standards and Compliance: Adhere to relevant standards (e.g., IEC, ANSI, IEEE) and local regulations for design and installation.
- Maintenance: Regular maintenance is crucial to ensure reliable operation and to address issues such as wear and tear, insulation degradation, and component failures.
- Documentation: Maintain accurate documentation of panel specifications, configurations, and maintenance records for future reference and compliance.
