All the computers that I've had (desktops and laptops) are/have been supplied with similar cables to the one on the right except in black colour.
They do when they connect a new dwelling up to the pole for the first time. They actually don't like it when things explode in their face. For some strange reason!![]()
These are the leads which were supplied with my "Houseworth" halogen oven (left) and my "Phillips" rice cooker (right). As they are interchangeable I use the right hand lead for both.
