Do I need a whole home surge protector?

What is a surge protector and do i really need one? First we will define what an electrical surge is . An electrical surge also known as a power surge is a brief but quick surge in voltage. Electrical surges can be caused by faulty wiring, lightning, power outages, electrical overload, and high-power electrical devices. A surge protector limits the voltage supplied to electrical devices. It does this by short-circuiting current to ground or absorbing the spike when a voltage transient occurs. With the amount of expensive electronics and the low cost of whole home surge protectors it is definitely worth it to get a whole home surge protector installed by a qualified and licensed electrician .
