CENELEC (European Committee for Electrotechnical Standardization) CENELEC is involved with the conversion of IEC standardization results into European Standards; almost 85 % of the European Standards are based on IEC work results or are identical with them. In addition, CENELEC prepares its own European Standards – focused on European requirements. Furthermore, CENELEC has the task […]

The Institution of Electrical Engineers (I.E.E.) was a British professional organisation of electronics, electrical, manufacturing, and Information Technology professionals, especially electrical engineers. The I.E.E. was founded in 1871 as the Society of Telegraph Engineers, changed its name in 1880 to the Society of Telegraph Engineers and Electricians and changed it again to the Institution of […]

The IET (Institution of Engineering and Technology) is one of the world’s leading professional societies for the engineering and technology community, with more than 150,000 Members in 127 countries and offices in Europe, North America and Asia-Pacific. The IET provides a global knowledge network to facilitate the exchange of ideas and promote the positive role […]

The 17th edition, released in January 2008, is the latest edition of BS7671, and became effective for all installations designed after 1 July 2008. One of the more significant changes is (chapter 41) that 30 mA RCD’s will be required for socket outlets that are for use by ordinary persons and are intended for general […]

Requirements for non-armoured cables with thermosetting insulation of rated voltage up to and including 450/750 V, which produce lower levels of smoke and corrosive gases under exposure to fire, compared with corresponding PVC-insulated cables specified in BS 6004.

British Standard BS 7671 “Requirements for electrical installations” is the national standard in the United Kingdom for low voltage electrical installations. For more click here.

High, Low and Extra Low Voltage. The International Electrotechnical Commission and its national counterparts (IET, IEEE, VDE, etc.) define high voltage circuits as those with more than 1000 V for alternating current and at least 1500 V for direct current, and distinguish it from low voltage (50 to 1000 V AC or 120 to 1500 […]
