Power surges can happen in the blink of an eye, but the damage they cause can cost you thousands. From fried TVs and computers to burnt-out HVAC systems and appliances, electrical surges are one of the most overlooked threats to your home’s safety.
If you’ve ever asked, “How does surge protection work?” you’re not alone — especially here in Central Texas, where storms and grid issues can lead to frequent voltage spikes. In this blog, the licensed electricians at Bowen Electric break down exactly what surge protection does, how it works, and why it’s essential for protecting your home or business.
What Is a Power Surge?
A power surge is a sudden spike in voltage that travels through your home’s electrical system. Standard U.S. homes operate on 120/240 volts, but a surge can temporarily increase that voltage to much higher levels, sometimes exceeding thousands of volts. When that happens, the excess electricity can overload circuits, melt internal components, or even start fires in extreme cases.
Common Causes of Power Surges:
- Downed power lines
- Utility grid switching
- Large appliances cycling on/off (like AC units or refrigerators)
- Faulty wiring or electrical overloads
Even if a surge doesn’t destroy something outright, repeated surges can wear down electronics over time, causing them to fail prematurely.
How Does Surge Protection Work?
Surge protection works by detecting excess voltage and diverting it away from your electrical system before it reaches sensitive devices. Most surge protectors use components called metal oxide varistors (MOVs), which act like pressure relief valves for your power supply. Here’s a simple breakdown:
- Electricity flows through your home’s wiring under normal conditions.
- If the voltage suddenly spikes, the MOV kicks in.
- The MOV safely redirects the excess electricity into your home’s grounding wire.
- Once the voltage returns to normal, the MOV stops conducting.
This all happens in fractions of a second — fast enough to protect computers, TVs, HVAC units, and even smart appliances from damage or destruction.
Two Main Types of Surge Protection
Not all surge protection is created equal. Depending on your home or business’s needs, you may want one or both of the following systems:
1. Point-of-Use Surge Protectors
These are the surge strips or surge-rated outlets you plug into the wall. They’re common for:
- Computers and monitors
- Home entertainment systems
- Gaming consoles
- Internet routers
Pros:
- Easy to install
- Affordable
- Provide basic protection
Cons:
- Limited to the device plugged into them
- Can’t handle large surges or whole-home threats
2. Whole-Home Surge Protectors
Installed directly into your electrical panel, these protect your entire home by stopping surges at the source.
Pros:
- Covers all appliances and outlets
- Protects HVAC systems, washers, dryers, ovens, refrigerators, and other appliances.
- Helps safeguard against external surges
Cons:
- Must be installed by a licensed electrician
- Slightly higher upfront cost, but significant long-term value
At Bowen Electric, we recommend whole-home surge protection for most Texas homeowners, especially if you’ve already invested in expensive electronics or smart devices.
Why Whole-Home Surge Protection Is Worth It
Still on the fence about installing a whole-home system? Here are just a few reasons why it’s one of the smartest electrical upgrades you can make:
- Save Money: Replacing a blown HVAC system, fridge, or washer can cost thousands. Surge protection helps prevent these disasters.
- Peace of Mind: You don’t have to unplug everything every time a storm rolls in.
- Protect Modern Tech: Today’s homes are filled with sensitive devices that weren’t common 10–20 years ago.
- Insurance Benefits: Some insurers offer discounts for homes with certified surge protection.
The average cost of whole-home surge protection is a fraction of what even a single appliance replacement would cost after a surge.
What Happens During Installation?
Installing a whole-house surge protector is a quick and non-invasive process when done by a qualified electrician. Here’s what to expect from Bowen Electric:
- Home Evaluation: We assess your electrical panel, wiring, and service capacity.
- Device Selection: We recommend a surge protector rated for your home’s specific load and needs.
- Installation: Our licensed electrician hardwires the surge protector into your main panel.
- Testing: We confirm the unit is working properly and safely, diverting voltage.
- Ongoing Support: We provide guidance on pairing your whole home unit with point-of-use surge protectors for added protection.
The entire process typically takes under two hours and can be done with minimal disruption to your home.
Should You Still Use Surge Strips?
Yes — in fact, combining whole-home surge protection with point-of-use strips is the best defense. Why? Because:
- Whole-home units stop big surges at the panel
- Plug-in surge protectors add a second layer of protection for ultra-sensitive devices
Think of it like locking your doors and also setting an alarm system. Together, they make your home a safer place.
Signs You Might Need Better Surge Protection
Are you unsure if your home is already protected? Watch for these red flags:
- Flickering lights during storms
- Frequent tripping of circuit breakers
- Electronics randomly shutting off or failing
- Outlets or plugs feel hot
- Visible scorch marks on outlets
If you notice any of these, it's time to have your system inspected, especially if your home is older or hasn’t had an electrical upgrade in the past 10–15 years.
