This page was last modified on 23 Aprilat The fundamental rule of protection against electric shock is provided by the document IEC “Protection against electric shock — Common aspects for installations and equipment” which covers both electrical installations and electrical equipment. Basic protection Fault protection.
The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. The values of body impedance depend on a number of factors and, in particular, on current path, on touch voltage, duration of current flow, frequency, degree of moisture of the skin, surface area of contact, pressure exerted and temperature.
Electrical fires are caused by overloads, short circuits and earth leakage currents, but also by electric arcs in cables and connections. ied

The necessary criterion is the admissible limit of touch voltage i. The following other wikis use this file: From Electrical Installation Guide. Preview Abstract IEC 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 conductive parts shall not be hazardous.

You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. An electric shock is the pathophysiological effect of an electric current through the human body.

Threshold of muscular reactions C 1 curve: The relationship between current and voltage is not linear because the impedance of the human body ifc with the touch voltage, and data on this relationship is therefore required.
