Electrical Installations – Standards & Regulation around the World

Electrical Installations – Standards & Regulation in Different Countries

Introduction

The construction and the characteristics, performances and tests to be carried out on HV, MV and LV (HV: High Voltage; V ≥ 60 kV.MV: Medium Voltage; 1 kV < V< 60 kV. LV: Low Voltage; V ≤ 1 kV) installations, as well as the equipment used are subjected to national and international technical standards and regulations.

The same way the manual operation of the equipment, for maintenance or network reconfiguration purposes, and the obligations of the owners and the operation personnel, as well the procedures to be followed, the documentation to be produced, the safety precautions to be implemented, and the protection equipment and clothes that shall be used during the operation are regulated by national and international standards and national laws.Electrical Installations - Standards & Regulation around the World

Wiring Regulations

Electrical Wiring Regulations are technical documents with an official character defining the characteristics and safety measurements to be followed during the design, construction and operation of an electrical power system.

Main Wiring Regulations in Several Countries

Main Wiring Regulations in several countries are:

Europe

Portugal

France: French Standards NF C 15-100 (Low Voltage) and NF C13-200 (High Voltage)

Germany: German Standards

United Kingdom: BS Standard 7671 (IET Wiring Regulations)

India, Pakistan, Bangladesh, Philippines & Other countries: IEC Standard 60364

United States of America

National Electrical Code (NEC) – NFPA Standard 70

Canada

Canadian Electrical Code (CSA C22), Part I to VI, and SPE-1000: Model Code for the Field Evaluation of Electrical Equipment

Middle East/Gulf Countries

Apart from the Kingdom of Saudi Arabia, these wiring regulations are mainly based on British Standard BS 7671.

Australia/New Zealand

Standard AS / NZS 3000:2007-Wiring Rules

Hong Kong

Code of Practice for the Electricity (Wiring) Regulations

Main Standards

Standards play an important role in electrical installations, since they provide a common language to everyone that is involved in the different phases of a project – design, manufacture, construction, testing and supervision.

Some of the main standards commonly used are:

International

Europe

United States of America
