This refers to a person coming into contact with a conductor which is live in normal circumstances see Fig. An example of differences between parameters used for calculations is the assumed resistance for the victim: This third edition cancels and replaces the second edition, published inand constitutes a technical revision.

In reality, a short pulse has a high frequency content, so at a first approx the expected behavior is similar. Basic protection Fault protection. EN tables for ac and dc systems follow.
