Most people think surges only occur during violent storms, when in fact a surge in power can take place any hour of the day or night and under any weather conditions. And a few people remember that their appliances need to be protected with a surge protector. The problem with most appliance surge protectors like what you would use on your fridge, the surge protector protects that fridge but your food ends up spoiled because the surge protector stops the power to the fridge when the power comes back on. This surge protector maintains the power to the appliance even after a power surge.
