Professional Training in Electrical Drafting
Introduction
The Electrical Drafting Training Program is designed to equip individuals with the practical skills required to prepare accurate and industry-compliant electrical drawings using AutoCAD and related drafting tools. The course covers lighting, power, panel layouts, single line diagrams (SLD), and wiring schematics for residential, commercial, and industrial projects. Trainees will learn how to interpret electrical designs, adhere to international codes and standards, and produce construction-ready drawings for real-world applications.
