COURSE OVERVIEW:

The Motor Control Centre (MCC) is the primary distribution hub for industrial motor loads, integrating power delivery with complex automation logic. This course provides a technical exploration of MCC engineering, focusing on the design requirements for reliability, safety, and operational efficiency. Participants will explore the mechanics of "Smart" and "Conventional" MCCs, learning how to bridge the gap between heavy electrical switchgear and sensitive digital control.

The scope of this training addresses the physical construction of MCCs, including busbar bracing, "Form" of separation, and the design of "Withdrawable" buckets. It covers the technical nuances of motor starting methods, from Direct-on-Line (DOL) to Variable Frequency Drives (VFDs), and the selection of protective devices to ensure compliance with IEC and NEMA standards. The curriculum provides a detailed focus on the secondary control circuits and the communication networks that link the MCC to the plant's PLC/SCADA systems.

Coverage includes the implementation of rigorous maintenance and diagnostic testing protocols, such as infrared thermography and contact resistance measurement. Attendees will learn to manage "Arc Flash" risks during racking operations and to troubleshoot complex control logic failures within the MCC cubicle. By combining engineering design principles with practical maintenance workflows, the course equips professionals with the expertise required to ensure the long-term integrity of critical industrial motor control assets.

COURSE OBJECTIVES:

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

• Define the design standards for MCCs according to IEC 61439 and NEMA.
• Differentiate between the various "Forms of Separation" (Form 1 to 4).
• Calculate busbar sizing and short-circuit bracing requirements.
• Design "Withdrawable" and "Fixed" starter units for diverse loads.
• Select and size contactors, thermal overloads, and circuit breakers.
• Integrate Variable Frequency Drives (VFDs) and Soft Starters into the MCC.
• Design and troubleshoot control logic for automated motor sequences.
• Implement "Smart MCC" communication (Ethernet/IP, Modbus, or Profibus).
• Execute safe "Racking" procedures for MCC buckets and breakers.
• Perform "Contact Resistance" (Ductor) and "Insulation" (Megger) testing.
• Utilize "Infrared Thermography" to identify hotspots in busbar connections.
• Develop a "Predictive Maintenance" schedule for critical MCC assets.

TARGET AUDIENCE:

This course is intended for Electrical Design Engineers, Plant Maintenance Managers, Industrial Electricians, and Control System Engineers.

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.
