What is IEC 60364-4-44 Ed.3:2018 ?

IEC 60364-4-48:2018 is an essential standard for electrical installations in low-voltage systems. It is a set of guidelines that outlines the requirements for wiring systems, including design, installation, inspection, and maintenance of these systems. The purpose of IEC 60364-4-48 is to ensure the safety and functionality of electrical installations in low-voltage systems.

Compliance with this standard is crucial for protecting users, preventing accidents, and maintaining reliable electrical infrastructure. The key requirements of IEC 60364-4-48 are as follows:

Wiring System Design: The standard outlines the requirements for the design of wiring systems. It recommends using a wiring system that is based on a modular, easy-to-install, and easy-to-maintain design. The wiring system should also be designed to minimize the risk of electrical hazards.

Cable and Fiber Optic Cable: The standard recommends using fire-resistant cables and fiber optic cables for electrical installations. These cables should be tested to ensure that they are suitable for the specific installation and meet the requirements of the building.

Circuit breakers: The standard recommends using circuit breakers that are suitable for the specific application and have a high thermal rating.

Enclosure: The standard recommends using enclosures that are suitable for the specific application and provide adequate protection from environmental factors such as moisture, dust, and heat.

Insulation: The standard recommends using insulation that is suitable for the specific application and provides adequate protection from electrical hazards.

Grounding: The standard recommends using grounding systems that are suitable for the specific application and provide adequate protection from electrical hazards.

Maintenance: The standard recommends conducting regular maintenance to ensure that electrical installations are in good working condition and comply with the requirements of the standard.

IEC 60331-4-7:2020 is an important standard for electrical installations in buildings. It focuses on fire resistance testing of cables used in buildings. The standard outlines the requirements for testing cables to ensure that they are suitable for the specific installation and meet the requirements of the building.

Compliance with this standard is crucial for protecting users, preventing accidents, and maintaining reliable electrical infrastructure. The key requirements of IEC 60331-4-7:2020 are as follows:

Cable: The standard recommends using cables that are suitable for the specific installation and have a high thermal rating.

Fire Resistance: The standard outlines the requirements for fire resistance testing of cables. The tests should ensure that the cable is not ignitible to fire and is not likely to contribute to a fire.

Brake: The standard recommends using brakes that are suitable for the specific application and have a high thermal rating.

Enclosure: The standard recommends using enclosures that are suitable for the specific application and provide adequate protection from environmental factors such as moisture, dust, and heat.

Grounding: The standard recommends using grounding systems that are suitable for the specific application and provide adequate protection from electrical hazards.

marking: The standard recommends marking cables with the appropriate markings to indicate their suitability for the specific installation and provide adequate protection from electrical hazards.

Maintenance: The standard recommends conducting regular maintenance to ensure that electrical installations are in good working condition and comply with the requirements of the standard.

In conclusion, IEC 60364-4-48 and IEC 60331-4-7:2020 are important standards for electrical installations in low-voltage systems and buildings, respectively. Compliance with these standards is crucial for protecting users, preventing accidents, and maintaining reliable electrical infrastructure.
