Voltages
As the country was being quickly wired in the early 1900's, a trade association of electricity producers and distibutors decided on their goal: Absolute max of 125/250V if you lived right next door to an electric plant, and an absolute minimum of 110/230 if you were way out of town, on a farm or something at the very farthest limits of the distribution network. This was further written in stone in the 30's with the TVA and REA. In my home, it fluctuates from 116.6 to 117.8 at different times I've been doing a wiring project.
