110/220 is old school voltage like twenty thirty years ago. These days we call it 120/240 give or take ten percent. I checked mine last week when I got done adding three dedicated circuits to my H/T system it was 130 volts. It always seems a little high around where I live. That reading will change during different times of the year so keep an eye on it.
What should a typical house voltage read/be?
My house voltage reads 123volts from a voltage meter(Fluke 87 True RMS Multimeter). I have my equipt.(Yamaha DSP-A1GL & Technics DVD-a10 Player) running through a Monster Cable HTS-3500 power center. The analog meter reads in at 123 volts as well. Is this normal? I thought a typical house voltage was 110v.
