110 V

at 60hz if that matters

220 to 250V for driers, welders and a few other things, different outlet,

all domestic is single phase, ag and industral is a combination of a bunch of voltages and three phase

110v-130v with most staying around 125 because it helps motors to run cooler.

Nother will fry a fridge comp. faster than under-voltage.

My house is rated at 110, but it is actually a hair over 130.
