The US uses 120 VAC and 240 VAC

Since 1984, the standard mains voltage in the US has been 120 VAC or 240 VAC, plus or minus 5 percent, not 110 VAC and 220 VAC, as stated in this module. So, for a typical outlet, the voltage could be from 114 to 126 VAC. If one were to measure 110 VAC at an outlet in the US, this could indicate faulty wiring or some other issue that could pose a danger.

Thank-you for posting this, as I was very confused - the module indicated USA was 220 volts!
