Think of power surges as tiny electrical storms that can happen inside your walls. They can be unexpected, but with the right protection, they don’t have to be a threat.

Power surges are more common than you might think, and they can pose a serious threat to your home’s electrical system. These unexpected spikes in voltage can come from a variety of sources, both inside and outside your home. Whether it’s a sudden lightning storm or an overuse of appliances, understanding the difference between external and internal power surges is key to protecting your home. 

In this article, our experienced electricians at Best Home Services will share insights into these power surges and how a whole-home surge protector can be your first line of defense.  

Understanding Power Surges 

A power surge is a sudden and temporary spike in the electrical current that flows through your home. This brief increase in voltage can pose risks to your electronic devices and home appliances.  

While the spike itself lasts only a fraction of a second, the damage it causes can be lasting. Power surges are more common during storm seasons, often caused by lightning, issues within the community power grid, or the operation of heavy appliances that turn on and off.  

External Power Surges 

External power surges are sudden jolts in electricity that occur due to factors outside your home. While these surges are less frequent than internal ones, they’re usually more potent and can cause significant damage if not properly addressed. The nature of external power surges means they’re often beyond our immediate control, but understanding their causes can help in preparing for them.  

External power surges generally stem from:  

• Lightning Strikes: Though rare, a lightning strike can release a substantial amount of electricity that may travel through the power lines into your home. 

• Utility Company Switching: Sometimes, utilities need to switch equipment or redirect electricity, causing abrupt increases in the voltage supply. 

• Power Grid Disturbances: Unexpected disruptions such as grid failures or industrial electrical changes can affect the stability of your home’s power. 

Internal Power Surges 

Internal power surges happen more frequently than many realize, often originating from the very appliances we rely on daily. These surges happen whenever a high-powered appliance like an air conditioner or refrigerator turns on or off. The sudden change in power demand can send a brief spike through your home’s electrical system.  

Think about the moments when you flick on a large appliance. That flicker you notice in the lights? It’s a hint of the power surge happening inside your circuits. These internal surges, while typically smaller than external ones, can still pack a punch, delivering up to ten times the normal voltage.  

This isn’t just a problem for older homes. Even modern residences with up-to-date systems can experience these micro-surges. However, in homes with outdated wiring or limited electrical capacity, the risk increases significantly, leading to more noticeable disruptions.  

Over time, frequent surges can trip breakers, blow fuses, and even cause damage to sensitive electronics with delicate circuit boards. 

How Power Surges Can Damage Your Home Appliances 

Appliances, especially those containing sensitive microprocessors, are at high risk of damage from voltage spikes. Devices like computers, televisions, and even refrigerators are not immune. These electronics rely on a steady flow of electricity to function correctly, and surges can disrupt this balance, leading to potential malfunction or permanent damage.  

Bottom line? Repeated minor surges can shorten the lifespan of appliances and gradually degrade performance before complete failure ensues.  

What Is a Whole Home Surge Protector? 

A whole-home surge protector is an essential device that protects your entire house against sudden voltage spikes. Installed at your main electrical panel, it acts like a security guard, intercepting any incoming surges from external sources like lightning strikes or grid fluctuations. This stops excess voltage from wreaking havoc on your home’s electrical system and appliances.  

So, how exactly does it work? When a surge attempts to travel through your wiring, the whole home surge protector automatically redirects it away from your appliances, preventing damage. This means your valuable electronics stay protected from both major accidents like extreme weather and more routine disturbances like the normal wear and tear of household appliances.  

While a whole home surge protector provides a comprehensive layer of security, pairing it with point-of-use surge protectors for sensitive electronics—such as computers or home entertainment systems—adds an extra level of defense. This combination ensures that even the smallest surges have minimal chance of causing harm, offering you peace of mind that your home’s electrical integrity remains intact. 

Protect Your Home from Power Surges  

While surges may seem minor at first glance, their impact can accumulate over time. To ensure your peace of mind, investing in a whole-home surge protector could be the best step you take for your household’s safety.
