Why your wall outlet is stuck at 120 volts
In short: Most of the world uses 230 volts, but America remains on a lower standard. This video traces how early industrial choices and massive infrastructure investment locked in our current electrical landscape.
The 120-volt standard isn't an arbitrary choice; it is a legacy of the late 19th-century transition to modern power. The history begins with Thomas Edison’s early systems, which operated at 110 volts. As alternating current became the dominant technology, these early figures influenced the eventual standardization of American home electricity.
The video explains that changing this standard today is a monumental task because it involves more than just swapping outlets. It examines the complexities of the split-phase system—which provides both 120 and 240 volts to many U.S. homes—and why decades of established infrastructure make a nationwide shift nearly impossible.
