Ok if you take a good look at the picture in the link I provided you will
see that any device screw to the box will be grounded even if there is no
place to place a ground to the device,many electrical device doesn't have a
ground log,and are grounded by the screw connected to the metallic box (when
its a metallic box) but on plastic box there is no grounding unless you
ground it by the metallic part in it...

in fact you don't ground the box itself,you ground any device connected to
it... and that make sense...
one device that come to mind just here is a light switch,you don't have a
ground log to those device,and if it fail and become hot,the next time you
touch it,and we have cooked Gordon on the menu....unless you put that damn
ground in that crazy plastic box...

was that clear enough?

or another device,a pull station,something we can relate to,after all we are
alarm professional,well most of us are,some are just online part seller
let say a light switch is just beside the pull station and the plastic box
that was used for it was not grounded,but the metallic plate in front of the
switch touch the pull station,and the switch fail,if you ground that plastic
box,you just maybe save the life of the next user of the light switch,its
not supposed to be used,we never expect anyone to make such a bad job in
electricity,that the ground in our plastic box for our fire alarm system is
the path that electricity will take to trip a faulty lighting circuit,but
let just say that the job been done by an electrical DIY,I prefer to do my
job right and have a no problem sleeping...

All those electrical laws are there to prevent the impossible to happen and
have someone killed by a lethal flow of electron,cause we should never
forget that electricity is as dangerous as fire,we are so used to have it in
our home that we don't think of electricity as a dangerous thing...would you
play with the natural gas line in your home?would you put a plastic tubing
in the gas line,and not make sure that the other end of the tube is not
grounded to prevent static electricity form building up and create an
explosion?

just think of this,and next time you see a plastic box with out a
ground,maybe you will understand why its a dangerous thing...
