Answer / mahavir jagdev

There are two answers to this question -

1. In olden times the earth plug was long and thick so that before any appliance get connected to the power, it it earthed and protects the person from shock as most of the equipments were made out of metal. It is thicker as the short circuit current is much more than the normal current the device takes.

2. With the modern three pin pligs the principle is the same but another safety feature has been added that the lower two power points open for insertion of the plug points only after the Earthing point has been insert. Again for safety.

1.longer so that earth is connected first and disconnected
last.2.Thicker to bear heavy earth fault current 3. Both, so
that connections to phase ,neutral and earth are not
interchanged

Answer / rahul

earth fault more adverse with respect to phase fullt to
servive in heating effect earth fult hole for the earth
socket in an electrical plug outlet made
thicker and lenghty?

Answer / bhigesh

it for safty .otherwise its not strong its danger to

Answer / tom hanks

Generally, to protect the socket from unwanted entries
(child finger or 2 plug entries without earth) all 3 holes
are closed from inside, to open it first earth Plug has to
insert with force which will open bottom holes too, thats
why Earth plugs are often lengthy and thicker.
