There are steps you can take to protect your home and belongings from a power surge and power surge damage, such as:
Lightning protection system: A lightning protection system (LPS) carries the current from a lightning strike into the ground, keeping it away from your home and electronics. An LPS is one of the best ways to prevent lightning damage, but it can be expensive and should always be installed by a professional.
Unplug electronics and devices: If a storm is approaching, unplugging electronics and other devices will ensure they're not damaged even if your home is struck by lightning.
Use surge protectors: Plug all your electronics and appliances into a surge protector if possible. A surge protector will help block surges from damaging your electronics. Be sure you're using a surge protector and not a regular power strip, which won't provide surge protection.
Update old wiring: If your home has old or malfunctioning wiring, it should be replaced. Faulty wiring can cause surges and also lead to a fire.
