Why is there no universal socket design in every nation?Balaji Viswanathan:
Though the United States developed the modern power delivery systems and electric plugs, other nations found their standards—60 Hz, 110V, and plug configurations—less efficient.
As a result, each country independently sought to improve what they considered an inefficient system for electricity delivery. The Germans preferred the 50Hz (which aligned better with the metric system) and 220V (offering more efficient power transmission). Meanwhile, the British modified the American plug into a safer, albeit bulkier, version.
Sadly for the Indians and Pakistanis, their innovation came after they left India in 1947, leaving the subcontinent stuck with the older English standards, while the English adopted newer plug standards. England and Europe were not in much communication, so Europe never adopted the English standard either.
Before that, the world wars interfered with any efforts for standardization: "Oh, you want to adopt the German plug system? Absolutely not."
Then, there were distinct ways in which electricity was delivered and used. For a long time, Italy had separate systems for powering light bulbs and non-lighting uses. As a result, they developed their own plug system to meet that specific need. Each plug system had its own set of advantages tailored to local requirements, and countries couldn't agree on one system being superior to another.
Once a country adopts a specific electrical plug system, switching to another becomes a major hassle (no pun intended). It would require dismantling every wall socket in homes, offices, and factories, as well as updating the production of electrical appliances. This change needs to happen all at once to avoid accidents, which would be costly and disruptive. That shock (again, no pun intended) and the pain of such an overhaul generally aren’t worth it. Most countries realized that there weren't many travelers carrying heavy electrical devices—who takes their microwave or TV when traveling?—and that easier solutions, like USB standards, made charging devices simpler. Consequently, there hasn’t been a strong push for global plug standardization (like the Type N plug).
In conclusion, every country developed its own system in parallel, aiming to replace what was seen as an inefficient American system. By the time nations began to communicate, two world wars had delayed all discussions of standardization. By the end of World War II, electricity had already become widespread, and switching to a common standard seemed too difficult and unnecessary, given the lack of demand for such a change.
