- InclinedPlane 8y ago"110" or "220" are legacy terms for mains voltages in the US, they are still in common use.
- cptskippy 8y agoThose are nominal rms values, the range is plus or minus 10%. I am not sure where it comes from but in the US it's not uncommon for supplies to be referred to as 220/110 rather than 240/120. They're generally understood to be the same thing.
