COURSE OVERVIEW:

The Motor Control Centre (MCC) and its integrated Low Voltage (LV) Circuit Breakers form the primary nexus for industrial automation and electrical distribution. This course provides a comprehensive technical exploration of MCC architecture, focusing on the seamless integration of power distribution with motor management. Participants will explore the mechanics of "Smart" and "Conventional" MCCs, learning how to manage the complex coordination between protective devices and control logic.

The scope of this training addresses the physical design and operational logic of LV switchgear assemblies, including busbar sizing, bucket design, and interlock systems. It covers the technical nuances of circuit breaker trip units, focusing on the precise adjustment of Long-time, Short-time, and Instantaneous settings to ensure selective coordination. The curriculum provides a detailed focus on the secondary control circuits, including contactors, overload relays, and variable frequency drive (VFD) integration.

Coverage includes the implementation of rigorous safety protocols for MCC operations, such as "Rack-in/Rack-out" procedures and arc-flash mitigation strategies. Attendees will learn to utilize modern diagnostics for monitoring motor health and to troubleshoot complex control logic failures within the MCC cubicle. By combining electrical engineering theory with practical hands-on maintenance workflows, the course equips professionals with the expertise required to ensure the high availability of industrial motor loads.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Identify the primary components of an MCC: Busbars, Buckets, and Control.
• Differentiate between NEMA and IEC standards for MCC construction.
• Select and size LV Circuit Breakers for specific motor and feeder loads.
• Adjust "LSI" trip unit settings to achieve selective coordination.
• Interpret and troubleshoot "Smart MCC" communication protocols (Ethernet/IP).
• Execute safe "Withdrawal" and "Insertion" of MCC buckets.
• Maintain and test contactors and overload protection devices.
• Integrate Variable Frequency Drives (VFDs) into the MCC architecture.
• Perform "Secondary Injection" testing on electronic trip units.
• Analyze the impact of "Harmonics" on MCC busbar heating.
• Implement "Arc-Flash" reduction technologies within LV switchgear.
• Conduct routine inspections and cleaning of MCC busbar systems.

TARGET AUDIENCE:

This course is intended for Industrial Electricians, Plant Engineers, Maintenance Technicians, and Control System Specialists.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
