A whole house surge protector protects your home from voltage spikes, limiting excess electrical current by blocking its flow or shorting it to ground, much like a pressure relief valve. This includes surges occurring not only from lightning, but the 60-80 percent of surges that occur from within your home – typically from major appliances cycling on and off. 

Today’s homes and families consume a great deal of power due to the abundance of electronic devices we use to function daily. As a result, damaging power surges are common today even when storms and downed lines are not a factor, with homes near the end of the power line being particularly vulnerable.
