9. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   Because the phases are 120 degrees from each other, the voltage between any two phases is sqrt(3) * 230V = 400V, compared to the 2 * 120V = 240V in the North American split phase system. While three-phase power is almost unheard of in individual North American residences, it is common in Europe for heavy loads such as kitchen stoves, air ...
