Electrical Installation and Safety
Wiring buildings safely — cables, earthing, protective devices, regulations and safe working practice.
Good installation practice keeps people safe from electric shock, fire and arc flash. In India, installations follow the National Electrical Code (NEC 2023), IS 732 (code of practice for electrical wiring installations), IS 3043 (earthing) and the CEA (Measures relating to Safety and Electric Supply) Regulations. Wiring work must be carried out by licensed electricians.
