Elcb is earth leakage circuit breaker. There are many
sensitivities in India. popular are 30ma, 100ma, 300ma,
500ma. For getting the correct corelation as to which
sensitivity is to be used for what application, it is
necessary to understand the effect of electric current on
the human being. I have the chart which shows the effect of
different ma current flowing through ones body and the
result. Usually below 30ma current is safe and gives only
tingling sensation to the person. But above 300ma can prove
dangerous and heart will stop.
For the second part you can use an earth megger and
connections are provided on any website or send me a mail
