Hi Gary:
The measurement of "leakage current" (or "touch current") in the protective
earthing conductor simulates the human body in series with the protective
earthing conductor. Supposedly, it is a measure of the human body reaction
to the current magnitude.
However, if the "leakage current" is less than the limit value, the
equipment is deemed acceptable. And vice-versa.
So, my question is: Is the measurement of "leakage current" a measure of
* human reaction to the current, or
* an equipment parameter?
Best regards,
Rich

Hi Rich,
Your comments remind me that I prefer to take each step in an analysis with
my "closest to the pin" estimate, and afterwards if I want to be
conservative, apply some overall discounting factor. The alternative method
of taking a conservative estimate for each step may lead to unrealistic and
non-transparent results.
Cheers,
Gary Tornquist
