Protection against electric shock (defining grounding, automatic disconnection of supply, and insulation).
In Saudi Arabia, the is actively working to complete national regulations for electrical installation based upon the IEC 60364 series of international standards, which are adopted as Saudi standards. This adoption is part of a broader trend across the Gulf region to align national electrical safety regulations with international best practices.
The most recent major update is the , published in September 2025. This edition completely restructures the document and introduces new topics, including: iec 60364.pdf
The effective current capacity is calculated by adjusting the base current rating ( I0cap I sub 0 ) using correction factors (
IEC 60364 provides guidelines for electrical installations in buildings, including: The most recent major update is the ,
The primary objective of IEC 60364 is to protect persons, livestock, and property against hazards and damage that may arise from the reasonable use of electrical installations. It provides unified principles to mitigate risks such as electric shock, thermal effects (fires), overcurrent, fault currents, and electromagnetic disturbances. Structure and Parts of the IEC 60364 Series
This section lays the groundwork. It outlines the basic objectives of the standard, such as protection against electric shock, thermal effects, overcurrent, and undervoltage. Part 4: Protection for Safety Structure and Parts of the IEC 60364 Series
While IEC 60364 is the dominant international standard, it coexists with other major electrical codes. Key differences include:
