And doesn't adhere to US electrical code.

Virtually all latin american countries are third world. Puerto Rico is latin american.

Their own people say it's third world. https://www.abc57.com/news/only-on-puerto-rican-businessman-says-home-is-third-world-country

The US is by definition not a third world country.

Depends on the definition. Originally used to simply describe the participants of WW2 and the cold war... Since the cold war, it's definition has more aligned with economics and industrialization rather than simply what side a country was on during a war. It's clear by my use of the term that I meant the modern definition, especially since we're talking in 2024... and not in 1989.

The modern definition of Third World

However, the meaning of Third World changed after the fall of the Soviet Union (and the end of the Cold War) in the early 1990s. "Third World" lost its political root and came to refer to economically poor and non-industrialized countries, as well as newly industrialized countries. Under this modernized definition, Third World countries are those that display economic, social, political, and environmental issues such as high poverty rates, economic instability, and lack of essential human resources compared to the rest of the world.

This shifting definition has led to significant confusion as to which countries could correctly be called Third World today. For example, going by the historical definition, nations such as Finland, Sweden, Ireland, and Switzerland were not aligned with either NATO or the Communist Bloc, and so were Third World countries. However, all four countries are economically prosperous today, and as such would not be considered Third World under the current modern definition of the term.

Adding insult to inaccuracy, when used in its modern context, Third World is considered to be a derogatory term that degrades countries which are developing and/or poor. This combination of confusion and disrespect has made Third World a largely obsolete term.

Under the "new" definition many parts of the USA could be considered third world, but I'm not going to argue that.

But fine, I'll modify my statement here...

Puerto Rico is a third world commonwealth.

Nobody... and I mean NOBODY has yet to address the actual electrical engineering part of my question. Instead we've gone off the political bullshit bandwagon. So I'm just going to take it that I'm correct, and that the original premise is bullshit.
