Electrical Building Services Design (AutoCAD Electrical) (EBSD-0926)
The Electrical Building Services Design (AutoCAD Electrical) program is a practical, project-driven course that prepares students to design safe, efficient, and code-compliant electrical systems for residential, commercial, and mixed-use buildings. Over three months, participants gain a solid foundation in electrical load calculation, distribution, protection, lighting, and earthing, while mastering AutoCAD Electrical to create professional drawings and documentation. Graduates leave with a complete design portfolio and the hands-on skills needed for careers in electrical design, MEP consulting, and construction projects.
The 3-month Electrical Building Services Design (AutoCAD Electrical) program blends essential electrical engineering principles with advanced CAD drafting skills. Participants learn to calculate electrical loads, size cables, design power distribution and protection systems, and produce professional single-line diagrams, lighting layouts, and comprehensive electrical drawings. Through practical case studies and a capstone project, students apply national and international electrical codes to real-world residential, commercial, and mixed-use building designs. Graduates leave with a professional design portfolio that showcases technical competence, industry-standard documentation, and proficiency in AutoCAD Electrical.
