The US is 120V, or split-phase 240 V. Depending where you are, it's allowed to be ±5% at the meter. NEC guidelines say no more than 3% voltage drop from there.
- nickff 6y agoYeah, I got the number wrong, 120/220 always messes me up; will leave previous comment as-is so that yours makes sense.
- lucioperca 6y agoYou might have 208V and not 240V if you have two 120V phases 120 degree apart.
