The following test report forms are related: This page was last modified on 23 Aprilat They also specify on which current level a circuit breaker for leakage to ground RCD, residual current protective device shall trip: Sizing and protection of conductors.
The values specified are deemed to be applicable for impulse durations from 0,1 ms up to and including 10 ms. Basic protection Fault protection. The degree of danger for ieec 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. Your basket is empty.

Click to learn more. This standard furthermore describes the effects of current passing through the human body in the form of single unidirectional 604779-2 impulses, sinusoidal impulses and impulses resulting from capacitor discharges. MV and LV architecture selection guide for buildings. The major changes with regard to the previous edition are as follows: This question already has an answer here: Standards and regulations distinguish two kinds of dangerous contact: Characteristics of particular sources and loads.
06479-2 See IEC Figure 20 and 22 below for ac and dc systems, respectively, and Table 11 and 13, again for ac and dc, for interpretation. Electrical fires are caused by overloads, short circuits and earth leakage currents, but also by electric arcs in cables and connections.
Preview Abstract IECwhich is a technical specification, describes the effects on the human body when a sinusoidal alternating current in the frequency range above Hz passes through it.

Protection against electric shocks and electrical fires. 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.
In reality, a short pulse has a high frequency content, so at a first approx the expected behavior is similar. Safety of current with duration [duplicate] Ask Question. Views Page Talk View ie History.

The threshold of pain for current flowing between extremities is in the order of 0. Of less interest if considering typical waveforms of supply distribution and equipment, but covering waveforms purposely generated, capacitor discharge, arc phenomena. Relevant IEC standards include: Home Questions Tags Users Unanswered. This third edition cancels and replaces the second edition, published inand constitutes a technical revision.
IEC For short pulses the standard indicates the energy as the main factor to determine if fibrillation may occur. Threshold of perception of current B curve: 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.
