How should power distribution be arranged for MCC and ICC equipment?

The key idea is safe, reliable, and properly protected power feeding for critical MCC and ICC equipment. Each critical MCC/ICC load should be on its own circuit with an appropriately sized breaker to provide overcurrent protection and allow fault isolation. Robust wiring in correct gauges and in proper raceways ensures the conductors can handle the load and withstand faults without overheating. This setup minimizes the chance that a problem on one circuit will affect other equipment and makes maintenance easier because faults can be traced and isolated quickly. For equipment that must stay up during outages or tolerates some power quality issues, a UPS or battery backup is prudent to maintain operation and protect against voltage sags, transients, and abrupt shutdowns. Using shared circuits with minimal protection increases the risk of nuisance trips, overheating, and cascading faults, which is not acceptable for critical MCC/ICC gear. No protection and reliance on extension cords are unsafe and violate typical electrical codes and best practices, potentially endangering personnel and equipment.
