This book is designed to give the intermediate science and theory necessary for electrical installation work. It covers Magnetism; Electrostatics; D.C. Machines; A.C. Theory and Machines; Transformers; Illumination; Efficiency, Work, Energy and Power; and Instruments. The book ends with both short answer and multiple choice tests for practice.switchgear. There are three main types of switchgear used in electrical systems and they are: 1 . a circuit breaker 2. a switch 3. an isolator The choice of switchgear for a particular application depends upon its function in the electrical system.
