Best Answer

In the UK, we use three pin plugs. Neutral (blue cable), Positive (brown cable), Earth (green and yellow striped cable). Positive is also known as the Live cable. The Earth cable is an important safety feature that directs electricity safely to earth should a short-circuit cause the device's metal body (a toaster, for instance) to become live and a dangerous shock is possible to any one touching the device's metal body. Before the modern standard colouring was introduced, black was the neutral, red the positive, and green the earth. This old colouring can still be found in buildings built before the change-over.
