What is IEC 60364-8-2 Ed.2:2018?

IEC 60364-8-2 Ed.2:2018 is a technical standard that provides guidelines for the design, installation, and testing of electrical installations in buildings. It specifically focuses on the requirements for low-voltage electrical installations. This standard is part of the series of international standards developed by the International Electrotechnical Commission (IEC) to ensure safety and reliability in electrical installations.

Scope and Purpose

The scope of IEC 60364-8-2 Ed.2:2018 covers the design, erection, and verification of electrical installations in residential buildings and other similar premises. It aims to provide clear and concise guidelines to designers, installers, and inspectors involved in these types of installations.

The purpose of this standard is to ensure the safety of people and property by defining appropriate measures to protect against electric shock, fire hazards, and other potential risks associated with electrical installations. It also emphasizes the importance of compliance with national regulations and ensures compatibility with other relevant international standards.

Main Requirements and Recommendations

IEC 60364-8-2 Ed.2:2018 outlines various requirements and recommendations to be followed during the design, installation, and inspection of electrical systems. These include:

Adequate Protection: The standard enforces the use of appropriate protective devices such as circuit breakers, residual current devices (RCDs), and surge protection devices. These devices help prevent electrical accidents and reduce the risk of damage to electrical equipment.

Cable Management: Proper cable management is crucial to ensure the integrity and longevity of electrical installations. The standard provides guidelines on routing, fixing, and protecting cables to minimize the risk of damage, overheating, or interference.

Earthing and Bonding: The standard emphasizes the importance of reliable earthing and bonding systems to ensure safety and proper functioning of electrical installations. It provides detailed guidelines on earthing arrangements, equipotential bonding, and protective conductor sizing.

Inspection and Testing: Regular inspection and testing are essential to verify the compliance and functionality of electrical installations. The standard outlines the procedures for initial verification, periodic inspection, and testing of low-voltage electrical systems.

Benefits of Compliance

Compliance with IEC 60364-8-2 Ed.2:2018 offers several benefits to both individuals and organizations involved in electrical installations:

Enhanced Safety: Following the requirements of the standard helps mitigate electrical hazards and reduces the risk of accidents, injuries, and property damage caused by faulty installations.

Improved Efficiency: Properly designed and installed electrical systems enhance energy efficiency, reducing energy waste and operational costs.

Legal Compliance: Adhering to this international standard ensures compliance with relevant regulations and facilitates smooth inspections and approvals from regulatory authorities.

Global Compatibility: Since the standard is recognized internationally, compliance allows for seamless integration and compatibility with electrical systems across different countries and regions.

In conclusion, IEC 60364-8-2 Ed.2:2018 plays a vital role in ensuring the safety, reliability, and efficiency of low-voltage electrical installations in residential buildings and similar premises. By following its guidelines, designers, installers, and inspectors can contribute to creating a safer environment for occupants and protecting valuable assets.
