Electrical surge protection

Nearly every appliance like refrigerators, microwaves, stoves, furnaces, central air conditioners and dishwashers contain microprocessor circuit boards to control their operation. All this equipment can easily be damaged by a power surge. A power surge may come from electrical storms, utility line power spikes or drops above and below normal operating parameters and even from inside the home caused by items that draw heavy loads on your electrical system like air conditioners, dryers, ovens and office equipment.
