Course Overview

Temporary electrical systems are essential for maintaining safe, efficient, and productive construction operations. From supplying power to heavy machinery and tower cranes to supporting site offices, lighting, and temporary facilities, well-designed electrical systems minimise operational risks, improve reliability, and ensure compliance with safety regulations and industry standards.

The Construction Site Electrical System Design programme by TransforMentors Academy equips participants with the practical knowledge and technical skills required to design, evaluate, and manage temporary electrical systems for construction sites. The course covers electrical load assessment, cable sizing and selection, power distribution design, routing, protection systems, testing and commissioning, risk management, and regulatory compliance.

Through practical exercises, real-world case studies, and interactive design activities, participants will learn how to develop temporary power layouts, perform essential electrical calculations and testing, coordinate with MEP disciplines, manage electrical risks, and utilise digital tools to support planning and monitoring. By the end of the programme, participants will be able to design and manage construction site electrical systems that are safe, reliable, efficient, and fully compliant with industry requirements.
