What is a Surge?
Basically, a surge is when something causes the an increase in the electrical charge in a power line, which will then increase the current that is going to your wall outlet. What can cause a surge? A lot of stuff. One thing you always hear about is lightning, though it’s not a very common cause of surges.
Another cause, and the most common, is electrical devices that require a lot of power. For example, a refrigerator, air conditioner, etc. When they turn on and off, they suck up a lot of energy and messes up the steady flow of voltage in the system.
