Why do you think we have different plugs around the world and not make a standard that is uniform for all?

Engineers developed the idea of a ground pin to make plugs safer in the 1920s. Many countries adopted these grounded plugs immediately, but they didn’t always make them the rule. So because different countries adopted innovations like these at different times, the plugs that they used changed throughout the years.

Why are plug sockets different around the world?

The reason why the world is now stuck with no less than 15 different styles of plugs and wall outlets, is because many countries preferred to develop a plug of their own, instead of adopting the US standard. Many Latin-American, African and Asian countries are still in the same situation that Brazil used to be in.

Why is the British plug so safe?

Prong Design: Like standard U.S. grounded plugs, the U.K. wall plug has three prongs. Although the built-in fuse adds bulk to the U.K. plug design, it’s also safer: In case of an unexpected electrical surge, the fuse simply blows and the electricity shuts off, preventing fires, electrocutions, and other accidents.

Which power supply can be used anywhere in the world?

Universal input means the power source input range is within AC 85 ~ 264 Volt and capable of operating at 50 and 60 Hz. These power supplies can be used anywhere in the world without adjusting a select switch for the input power.

What is the difference between AC power plugs and sockets?

AC power plugs and sockets connect electric equipment to the alternating current (AC) power supply in buildings and at other sites. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world.

Why are there so many different types of plugs and sockets?

So basically, there are more than a dozen types of plugs and sockets used in different parts of the world today because standardisation efforts were disrupted by the World War II. Also, second efforts at standardisation came too late; at a point where many countries had adopted their native plug systems beyond a point of no return.

What plugs are compatible with a technical standard TIS 166?

A technical standard may include compatibility of a socket with more than one form of plug. The Thai dual socket is specified in figure 4 of TIS 166-2549 and is designed to accept Thai plugs, and also Type A, B, and C plugs.

Which country first adopted Type N plug and socket system?

Besides, for a country to change its whole plug infrastructure, that’d be a whole lot of work. It wasn’t until 2007, however, that Brazil adopted the Type N plug and socket system. This made it the first country in the world to adopt Type N as its sole standard plug and wall outlet.
