TC 64 – Electrical installations and protection against electric shock rss. Preview Abstract IEC The fundamental rule of protection against electric shock is lec by the document IEC “Protection against electric shock — Common aspects for installations and equipment” which covers both electrical installations and electrical equipment.
Standards and regulations distinguish two kinds of dangerous contact: The protection of persons against electric shock in LV installations must be provided in conformity with appropriate national standards, statutory regulations, codes of practice, official guides and circulars etc. Our prices are in Swiss francs CHF. Connection to the LV utility distribution network. 6479
When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if the current is not interrupted in a very short time.
Hazardous-live-parts shall not be accessible, and accessible 64079 parts shall not be hazardous. The following test report forms are related: Protection against electric shocks and electrical fires. Protection measures are described in Protection against electrical fire risks.
Connection to the MV utility distribution network. Main page How to browse and search Random page. The fault current raises the exposed-conductive-part to a voltage liable to be hazardous as it generates a touch current through a person coming into contact with this exposed-conductive-part see Fig. The contents of the corrigenda of October and June have been included in this copy.
Residential premises and other special locations. Contact with live part Direct contact. Relevant Ifc standards include: Sizing and protection of conductors. Its passage affects essentially the muscular, circulatory and respiratory functions and sometimes results in serious burns.
The impedance values indicated in this technical specification result 604799 a close examination of the eic results available from measurements carried out principally on corpses and on some living persons.
Energy Efficiency in electrical distribution.
This refers ic a person coming into contact with an exposed conductive-part which is not normally live, but has become live accidentally due to insulation failure or some other cause.
