Our homes are full of electronics and appliances that play a critical role in our daily lives, from computers and TVs to refrigerators and air conditioning units. However, all these devices are vulnerable to power surges, which can cause significant damage. Without proper surge protection, one power surge could ruin expensive equipment and lead to costly repairs or replacements.
In this post, we’ll explore what power surges are, their causes, and why installing surge protection is essential for safeguarding your home’s electronics.

What is a Power Surge?
A power surge is a sudden and brief increase in voltage in your home’s electrical system. Household voltage in the U.S. typically operates at 120 volts, and any spike above that can cause problems. Minor surges may go unnoticed but can gradually degrade your devices, while larger surges can fry electronics in an instant, requiring costly replacements.
Causes of Power Surges
Power surges can be caused by several factors, both inside and outside your home:
Lightning Strikes: A lightning strike doesn’t have to hit your house directly to cause a surge. It can enter through power lines and deliver a massive voltage spike to your home.
Downed Power Lines or Grid Issues: Issues with the local power grid, like a power line falling or electricity being restored after an outage, can result in surges.
Appliance Overload: Large appliances such as refrigerators and air conditioners can create internal power surges when they cycle on and off, straining your electrical system.
Faulty Wiring: Older or damaged wiring can cause inconsistent voltage regulation, making your home more susceptible to surges.
How Power Surges Affect Your Electronics
Surges can cause immediate damage to your devices, particularly sensitive electronics like computers and TVs, by overloading their circuits. Even smaller, frequent surges can reduce the lifespan of electronics, leading to gradual wear and tear that shortens the overall durability of your devices. For computers and other data-driven devices, surges can also result in lost data, causing even more inconvenience and potential costs.
What is Surge Protection?
Surge protection involves using devices designed to divert excess voltage away from your electronics, keeping them safe from surges. Surge protectors work by directing excess electricity into the ground, ensuring that only the normal level of voltage reaches your devices.
Types of Surge Protectors

Power Strip Surge Protectors: These are common plug-in devices that provide protection for individual electronics. However, they only offer limited protection and are not sufficient for larger surges, such as those caused by lightning.

Whole-Home Surge Protectors: Installed at your home’s electrical panel, these devices offer protection for your entire house, guarding against both internal and external surges. They prevent damage from larger events like grid surges or lightning and also mitigate the impact of smaller surges from appliances.
Point-of-Use Surge Protectors: These plug-in protectors add an extra layer of defense for particularly sensitive electronics, such as computers or entertainment systems.
Why Whole-Home Surge Protection is Essential
While individual surge protectors are useful, they don’t provide comprehensive protection. Whole-home surge protectors act as the first line of defense by stopping excess voltage at the electrical panel, shielding all the devices in your home. This type of protection is particularly important in areas prone to severe weather, such as Texas, where lightning strikes are more common.
Benefits of Surge Protection
Prevents Costly Damage: Surge protectors prevent expensive damage to electronics, saving you money on repairs and replacements.
Extends the Lifespan of Electronics: Protecting against small, repeated surges helps extend the lifespan of your devices.
Reduces the Risk of Electrical Fires: Whole-home surge protection also helps safeguard your electrical wiring, reducing the risk of fire caused by overloaded circuits.
Conclusion
Surge protection is an essential investment for any homeowner looking to protect their valuable electronics. By installing whole-home surge protection, you can prevent damage from both external and internal power surges, ensuring your devices last longer and saving you from costly repairs.
