Electronic equipment manufactured today are designed to
handle fluctuations in voltage. If the voltage gets too high,
a fuse blows, too low & the unit will not work.
Motors in refrigerators, washers, & dryers can be damaged by
low voltage. They tend to draw more current under low voltage
conditions. Most motors fail with power-on surges after
power is restored after an outage.
Getting that UPS was a very good idea.
