Can surges cause damage?

Yes. Today’s computerized appliances and electronics can be damaged or destroyed by over-voltage surges or spikes. That includes computer equipment and peripherals; electronic equipment such as stereos, TVs and VCRs; household appliances, including washers, dryers, refrigerators, dishwashers, microwaves, food processors, blenders and can openers; and other electronic devices such as fax machines, telephones and answering machines. Any electronic device that contains a microprocessor is susceptible to damage from transient voltages.
