Why are so many produces marked 110 VAC or 220 VAC? That was the voltage in the early 1900s that was 100 years ago. I have not seen that voltage anywhere in 50 years. The voltage at every house I have lived at in TN, IL, MI, AZ, NC, MD, are all 120 VAC and 240 VAC that was many years ago. I bought a new hot water heater and electric stove they were both marked 220 VAC. The new welder that I just bought is marked 220 VAC. Why can't manufactures get it together there is no 110 or 220 volts in this country. The voltage where I use to work was 492 volts on L1 and L2 and 493 on L3 and the offices were 120 VAC.
