Part 7 addresses specific locations where standard installation rules are modified or supplemented due to increased risks or unique operating conditions. This part is organized into sections covering:

Standard industrial and residential networks. Offers high fault current for fast breaker trips. Directly earthed at the transformer. Connected to local independent earth electrodes. iec 60364.pdf

: Ensuring that if an insulation failure occurs, exposed conductive parts (like metal appliance casings) do not present a dangerous voltage. This is achieved through protective earthing, protective equipotential bonding, and the automatic disconnection of supply. Thermal Protection and Overcurrent Directly earthed at the transformer

This foundational part defines the scope and objective of the entire IEC 60364 series and specifies the for an electrical installation. It addresses the fundamental principles, assessment of general characteristics, and the core definitions that are used throughout the series. It also includes the overall philosophy of protection—starting from the concept of “basic protection” (protection against direct contact) and “fault protection” (protection against indirect contact) that underpins all modern electrical safety. Isolation and Control (IEC 60364-5-53)

This section defines how environmental external influences (temperature, water presence, mechanical stress) affect the selection of cables. It provides exhaustive tables for based on specific installation methods—such as cables enclosed in conduit, buried directly in the ground, or run openly on cable trays.
