Electrical Installation Technology, Third Edition covers the wide range of subjects that come under the headings of electrical science, installations, and regulations. The book discusses electromagnetism; inductance; static electricity; d.c. circuits; voltage drop and current rating; distribution; and wiring techniques. The text also describes o.c. motors and generators; a.c. motors, transformers; power-factor improvement; earthing and earth-leakage protection; testing; illumination; and the general principles of temperature and heat. Communication systems and equipment; electronics; and site and office management of electrical installation business are also considered. Students taking the electrical installation technicians, electrical technicians, and electrical engineering courses will find the book useful.Earthing Conductors and Circuit Protective Conductors The earthing lead is the final conductor to the earth electrode. ...
