COURSE OVERVIEW:

The accuracy of load estimation is the cornerstone of electrical system design, ensuring that infrastructure is neither dangerously undersized nor wastefully over-engineered. This course provides a comprehensive engineering framework for calculating the electrical requirements of various facilities, from residential complexes to heavy industrial plants. Participants will explore the variables that influence power consumption, focusing on how to translate architectural and process requirements into precise electrical demand figures.

The scope of this training addresses the technical methodologies used to determine connected loads, maximum demand, and the application of diversity and demand factors. It covers the analytical requirements for sizing transformers, feeders, and switchgear based on calculated projections. The curriculum provides a detailed focus on the impact of non-linear loads and harmonics on system sizing, ensuring that the resulting design is resilient enough to handle modern electronic equipment and variable speed drives.

Coverage includes the interpretation of international electrical codes, such as the NEC and IEC, to ensure that demand calculations meet regulatory safety margins. Attendees will learn to utilize advanced software tools and manual calculation techniques to perform comprehensive load audits and growth forecasting. By combining theoretical power engineering with practical design scenarios, the course equips professionals with the expertise required to deliver optimized electrical infrastructure that balances performance with cost-efficiency.

COURSE OBJECTIVES:

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

• Define and differentiate between Connected Load and Maximum Demand.
• Apply Diversity Factors and Demand Factors to various load categories.
• Perform detailed load estimations for lighting, power, and HVAC systems.
• Calculate the electrical requirements for specialized industrial machinery.
• Determine the starting and running loads for large electric motors.
• Account for future load growth and expansion in design calculations.
• Analyze the impact of power factor on demand and equipment sizing.
• Sizing transformers and distribution panels based on calculated demand.
• Utilize load schedules to organize and track system requirements.
• Evaluate the effect of non-linear loads on neutral sizing and harmonics.
• Perform voltage drop calculations for long-distance feeders.
• Ensure compliance with international standards for load estimation.

TARGET AUDIENCE:

This course is intended for Electrical Design Engineers, Project Consultants, Facility Planners, and Senior Estimators responsible for infrastructure sizing.

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.
