why earth hole size is biggest in plug point?
Answer Posted / vikas jauhari
There is no connection with cross sectional area and least
resistance path for short circuit current.
The size of earth pin is longer and bigger because of only
two following reason (you may refer BS1363)
• The longer earth pin ensures that the earth path is
connected before the live pins, and remains connected after
the live pins are removed.
• The design of the earth pin being of a larger
dimension prevents it from being inserted into the phase or
neutral sockets should this be attempted in error.
so don't get confussed
