I was pondering this question earlier today while I rewired a 4-way adaptor to have a longer lead. When was the last time that I actually had to change a plug. While I was a child I changed plugs all the time. I loved to play around with electrical gadgets that I had acquired through jumble sales and alike. These items often required a plug to be connected and therefore I spent quite a number of weekends messing around with screwdrivers, wire clippers and even in some cases soldering irons.
I remember that in school, both primary and secondary, I was taught how to change a plug. I was taught the colours of the wires inside a cable and how they related to the electrical mains supply. I understood which terminals within a plug these had to be connected to and I knew how to strip the cable to the correct lengths.
These days most electrical items come with a plug moulded onto the wire. It is rare that you have to change a fuse let alone rewire the plug. Before today I really can’t remember the last time that I saw the inside of a plug. Are children even taught, what was once considered a necessary life skill, in schools?
So I ask you, when did you last wire a plug? What colour is the earth wire? Does blue connect to the neutral terminal or the live terminal? Finally, is it the earth or the live terminal that has the fuse?
