Safety In Electrical Installations
Over last few decades, there has been significant increase in residential, commercial and other buildings in all major cities of the world. This has led to a significant rise in the installation of electrical wiring and electrical services in all types of buildings in urban, semi-urban and rural areas. Good quality electrical installation shall ensure prevention from accident such as electrocution, fire and shall offer trouble free long life for the connected equipment.
To ensure safety of persons and apparatus against electrical faults, it is necessary to follow the requirements for protection as mentioned by various Indian Standards. It is also the requirement of the time that our electrical engineers and technicians shall be familiar to correct practices.
Bureau of Indian Standards through its Electrotechnical Division Council (ETDC) is involved in the preparation of Indian Standards/ Codes in the field of electrical engineering. The Electrical Installations Sectional Committee, ETD 20 under ETDC is responsible for preparation of Indian Standards for safety and related matters in designing, erection and maintenance of electrical installations.
This handbook is based on the National Electrical Code of India and intends to provide technical guidance for wiring installations in buildings. The design, installation and other features given, are to understand the purpose and application in a simplistic way. This will help electrical engineers and technicians to understand the basic need and procedure of testing for safe and reliable electrical LV installations.
All electrical installations in India come under the purview of the Indian Electricity Act, 2003 and the rules and regulations framed, thereunder. Notwithstanding, the provisions given in this document, the provisions of Indian Electricity Act, 2003 and the rules and regulations framed have to be necessarily complied with.
It is not a comprehensive guide, for detailed information, National Electrical Code of India and IS 732:2019 may be referred.
