[RE-wrenches] 230Vac load on OB FX2524T system

[August Goers]

Many appliances, motors, AC units, etc are rated for 230 volts, but really
they work for our modern 240 volt services. If you do a quick web search,
it appears that US standard voltages over the years have morphed from 110
to 115, to 120 volt:
