There are many different types of voltage plugs and sockets in countries around the world, and other countries can also learn a lot about the design of electrical sockets from the British wall socket plugs.
Why is the UK wall plug with grounding called the safest power plug?
Probably many people who go to the UK for the first time will show a surprised expression when they see the British plug; There are three bulky rectangular pins. At first glance, it feels like an inefficient and cumbersome plug type; Especially compared to European plugs and American plugs.

But a lot of times, the surface is deceiving, and in fact, the English wall plug is a classic design, and it is much safer than the plugs in other countries around the world. Although the design of the British plug is relatively bulky, it will be safer without adding a certain weight.
1. Plug Pins:
Like the American earthing plug, the British plug also has three pins, and the safety design point of the British plug is that half of the pins of the zero live wire are wrapped by insulators, which can prevent accidental contact and cause the risk of electric shock. So even if the UK plug is not fully inserted into the socket, the exposed part does not pose a danger.

2. Socket Design:
In many countries, voltage sockets can be easily plugged into sockets with screwdrivers, forks or children's fingers. And in the UK, at least two screwdrivers are required to open a UK socket. The grounding wire of the British plug is slightly longer than the neutral wire, and this grounding is responsible for "opening" the protective door of the socket, so that it can be inserted into the neutral wire for power.
3. Built-in fuse:
During the Second World War, due to the shortage of copper, the British government designed the fuse on each plug, instead of wiring them directly, although the built-in fuse increased the volume of the British plug, but in the event of an accident, the anti-surge will automatically cut off the power supply, which can effectively prevent fire, electric shock and other accidents, which is safer to use and more convenient to repair.
4. Circuit Design:
Finally, the British plug for wiring is not only intuitive, but also well-designed. Once the plug and wire are broken, the neutral live wire is the first to be disconnected, and the grounding wire is still connected, effectively preventing the risk of electric shock.
The design of the British plug is more people-oriented and safety-oriented. It has been perfectly processed from the details to the general one, and it is indeed safer than other plug types.
