When I buy an electrical gadget, it often comes with a moulded plug

Just out of curiosity, can anybody explain precicely what hazards
these protectors are protecting the plug from ?


I've often wondered that myself. The brass pins are much tougher than the
plastic protector.

Mind you, I once had a machine part delivered in a box crammed full of
polystyrene packaging chips - the part was entirely made of rubber :-)
