COURSE OVERVIEW:

The design of electric switchboards is a fundamental engineering discipline that ensures the safe and efficient distribution of power within industrial and commercial facilities. This course provides an advanced look at the structural and electrical requirements for both low-voltage and medium-voltage switchboards, focusing on the integration of protective devices and busbar systems. Participants will examine the transition from conceptual single-line diagrams to the detailed engineering of metal-enclosed and metal-clad assemblies.

The scope of this training addresses the rigorous international standards—such as IEC 61439 and IEC 62271—that dictate the design limits for short-circuit withstand, thermal performance, and insulation coordination. It covers the technical nuances of compartmentalization and internal arc classification, ensuring that the final design provides maximum safety for personnel. The curriculum focuses on the selection of primary components, including circuit breakers, disconnect switches, and instrument transformers, while providing a framework for managing the mechanical stresses of high-current events.

Coverage includes the interpretation of system requirements to optimize the physical footprint and the electrical performance of the switchboard. Attendees will learn to conduct thermal calculations and short-circuit analysis to validate the design before manufacturing. By focusing on both the mechanical housing and the electrical protection and control layers, the course equips professionals with the expertise required to design resilient switchboards that meet the demanding requirements of modern energy infrastructure.

COURSE OBJECTIVES:

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

• Design switchboard architectures according to IEC and IEEE standards.
• Select appropriate Low Voltage and Medium Voltage circuit breaker technologies.
• Calculate busbar dimensions for continuous current and short-circuit forces.
• Implement compartmentalization strategies to enhance personnel safety.
• Design internal arc pressure relief systems for switchgear enclosures.
• Coordinate insulation levels to prevent dielectric failure and tracking.
• Select and size instrument transformers for metering and protection.
• Analyze thermal dissipation and design effective cooling for switchboards.
• Create detailed mechanical layouts and internal wiring schematics.
• Evaluate the impact of environmental conditions on switchboard materials.
• Implement digital monitoring and communication interfaces in switchboards.
• Conduct design verification and type-testing analysis for compliance.

TARGET AUDIENCE:

This course is intended for Electrical Design Engineers, Switchgear Manufacturers, Consultants, and Senior Engineering Leads involved in power distribution design.

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.
