British Plugs Are Better Than All Other Plugs, And Here's Why
The British electrical plug is considered a great design due to its safety features. It has special shutters that prevent objects from being poked into the live holes unless the longer earth pin is inserted first. The live and neutral pins also have insulation halfway up, preventing electric shock if the plug is partially pulled out. Inside, each plug contains a fuse, a design choice made after WWII due to copper shortages, which makes the electrical system safer. The wires are color-coded: blue for neutral, brown for live, and green/yellow for earth. The earth wire acts as a safety return path for electricity if something goes wrong. A clever design feature is that the earth wire is intentionally left with some slack, so if the cable is pulled, the live and neutral wires will disconnect before the earth wire, ensuring safety.
