Duration 5 Days

Introduction

This course covers many subjects related to electrical drawing & wiring such as components of a drawing, symbols, diagrams, CAD & management of drawing.

Who Should Attend

Electrical Engineers, Technicians and any one need to learn Electrical Drawings.

Course Objectives

1. Understand Drawings components, sizes and scales.
2. Recognize symbols used in electro technology and governing standards
3. Differentiate between different types of diagrams
4. Manage drawing process flow.

Course Outlines:
