The standard ("Electrical Installations for Buildings") is the foundational global blueprint for low-voltage electrical systems. Published by the International Electrotechnical Commission (IEC), this multi-part standard dictates how electrical engineers, contractors, and safety inspectors design, install, and verify electrical systems worldwide.
