Chapter – Protection against electric shocks and electric fires. The degree of danger for the victim is a function of the magnitude of the current, the parts of the body through which the current passes, and the duration of current flow.
Connection to the MV utility distribution network. Contact with parts in fault conditions Indirect contact.
The following test report forms are related: Do you need a multi-user copy? Residential premises and other special locations.
Possibility 6047-91 irreversible effects AC zone: The relationship between current and voltage is not linear because the impedance of the human body varies with the touch voltage, and data on this relationship is therefore required.
Basic protection Fault protection.
Ventricular fibrillation unlikely to happen C 2 curve: 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.
You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.

The following page uses this file: The contents of the corrigenda of October and June have been included in this copy. Electrical fires are caused by overloads, short circuits and earth leakage currents, but also by electric arcs in cables and connections.

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.
