UK Electrical Plug Protections

British 240v/50Hz electricity can injure people, so electrical plugs are designed so that live electrical pins are never exposed.

1. the pins’ position and orientation are such that the plug can only fit one way in the socket

2. the pins are insulated near the plug body so that electric shock is not possible via the exposed pin if the plug is not pushed all the way in but still
making contact.
