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. This course will introduce the learner to some basic electrical drawings. Going a step further, the course also describes the equipment and tools that enable an electrician to test and maintain the installations. Such test equipment includes an ammeter, a galvanometer and a multimeter. Related topics on how a moving-coil meter operates and how to select a meter are also covered. This course will be of interest to professionals in the areas of construction, electronics and engineering who would like a greater knowledge and understanding of electrical drawings and test equipment.
Having completed this course the learner will be able to: - Describe the various terms associated with electrical drawings; - Identify the plans and drawings that are included in electrical drawings; - Discuss the uses of electrical test equipment such as ammeter, galvanometer, voltmeter, ohmmeter, multimeter; - Explain how a moving-coil meter operates; - Apply the general points for selecting a meter; - List the safety precautions for working with electrical test equipment.
