Installing a safe electrical system begins with a well-planned electrical drawing. Construction projects require work drawings and specifications to guide electricians in installing electrical equipment. Besides being a customer requirement, these plans and drawings provide specific instruction to electricians. Standard symbols and lines are used to represent the different types of material, raceways, conduits, and circuit connections. Reading and interpreting these drawings accurately is therefore an important skill for electricians. The Alison free online course “Introduction to Basic Electrical Drawings and Test Equipment”
