What Causes a Surge?
A power surge is a sudden, brief spike in electrical voltage that can damage or destroy electronic devices and appliances. Power surges can be caused by several factors:
-
Lightning Strikes A direct or nearby lightning strike can send a massive voltage spike through electrical lines, overwhelming your home's wiring.
-
Utility Grid Switching When the power company switches grids or restores power after an outage, the sudden change in electrical flow can cause a surge.
-
Large Appliance Cycling High-powered appliances like air conditioners, refrigerators, or furnaces can cause internal surges when they turn on or off.
-
Faulty Wiring or Electrical Overloads Poor wiring, lack of proper grounding, and overloaded circuits increase surge risks and severity.
