Answer Posted / h r jadhav
body earthing resistance max limit is prescibed by
electricity rules 1956. in any case touch potential step
optetial shall not be more so the curent passing live body
more than 30 miliamp.in case of 415 volts max earth
resistance shall not be more than 3 ohms. and in case of 11
kv it is to be less than .6 ohn.
