In today's increasingly digital world, our homes are more vulnerable than ever to power surges. Sudden spikes in voltage can wreak havoc on our electronics, from frying delicate smartphones to damaging expensive appliances. That's where surge protectors come in.
In This Article:
Why Are Surge Protectors Important?
Surge protectors are devices designed to safeguard electronic equipment from sudden, harmful increases in electrical voltage known as power surges. These surges can be caused by various factors, including lightning strikes, power grid fluctuations, and the sudden switching on or off of large appliances.
Items that are affected:

Smart Home Devices (Thermostats, Security Systems, Lighting): Protect your connected home network.
Modems and Routers: These are crucial for internet connectivity and are easily damaged.
Printers and Scanners: Protect your office equipment from unexpected surges.
How Do Surge Protectors Work?
Surge protectors act as a safety valve for your electrical system. They contain components like metal oxide varistors (MOVs) that divert excess voltage away from your devices and into the ground. This protects your electronics from damage, even during severe electrical storms. There are two main types of the protectors, Power Strip Protectors and Whole-Home Protectors.
Power Strip Surge Protectors
You may already have one of these! Power Strip Surge Protector is a combination of a power strip and a surge protection device. This circuitry absorbs and diverts excess voltage away from your devices during a power surge. This protects your electronics from damage while allowing you to conveniently plug multiple devices into a single outlet. These are good for your office computer, TV, and anywhere in the home where you keep important devices plugged in. It only protects the items plugged into it.
Pros:
Easy to install: Simply plug them into a wall outlet and connect your devices.
Portable: You can easily move them around your home.
Multiple Options: Power strip protectors come in various models to suit different needs
Cons:
Limited protection: They only protect the devices plugged directly into them.
May not handle large surges: Their capacity to absorb surges is limited.
Can overload: Connecting too many high-power devices can overload the power strip.
Doesn’t protect large appliances: These strips cannot be used on refrigerators, ovens, washing machines, dryers, or any other large appliance.
Safety Tips For Power Strip Surge Protectors
Surge protector safety is paramount to ensuring both effective protection and preventing hazards. Always choose surge protectors from reputable brands and look for certifications like UL Solutions. Avoid overloading surge protectors; plugging in too many devices or devices with high power demands can exceed the protector's capacity, leading to overheating and fire risks. Inspect surge protectors regularly for signs of damage, such as cracks, discoloration, or loose outlets, and replace them immediately if any are found.
Do not use surge protectors in wet or damp locations, as this poses a serious electrical shock hazard. For optimal protection, especially for valuable electronics, consider a layered approach combining whole-home surge protection with individual surge protectors at point of use.
Finally, remember that surge protectors have a limited lifespan and may degrade over time, so it's advisable to replace them periodically, typically every few years, even if they appear to be functioning correctly.
Whole-Home Surge Protectors
A level-up from the power strip surge protector is the Whole-Home Surge Protector. It provides comprehensive protection for your entire home's electrical system from power surges. Unlike power strip surge protectors that only protect devices plugged directly into them, a Whole-Home Surge Protector is installed at the main electrical panel of your home. This device intercepts and absorbs surges before they reach any of the electrical outlets or appliances in your house. This offers the highest level of protection for all your electronics, including sensitive appliances, entertainment systems, and even major home appliances like refrigerators and air conditioners.
Pros:
Comprehensive protection: Protects your entire home's electrical system.
Handles large surges: Designed to withstand powerful surges that could damage your entire home's wiring.
Peace of mind: Offers greater peace of mind knowing your entire home is protected.
Reduces Fire Hazard: By preventing power surges, whole-home surge protection minimizes the risk of electrical fires.
Saves Money: In the long run, a whole-home surge protector is worth the investment because it will keep you from having to replace every appliance and electronic destroyed by a surge.
Home Value: Having a whole home protector will be a green flag to homebuyers, especially in high-risk areas.
Cons:
More expensive upfront: More costly than power strip protectors.
Professional installation required: Requires the services of an electrician.
Maintenance: Like any protection device, you will need to periodically inspect your surge protector to ensure it’s in functioning order.
Whole-Home Protector Maintenance
Like every home protection source, it is always wise to keep an eye on your surge protector to make sure it’s able to protect you. Unlike a power strip protector, you don’t need to worry about placing it in the wrong spot, but here are some things you should do:
1. Regular Inspections:
Status Indicators: Most whole-home surge protectors have indicator lights (LEDs) that show the device's status. Check these lights periodically (e.g., monthly) to ensure the protector is working. A change in the indicator light's status may signal a problem.
Physical Condition: Inspect the surge protector for any signs of physical damage, such as cracks or discoloration. If you notice any damage, contact a qualified electrician for inspection and possible replacement.
2. Testing (Recommended):
Professional Testing: It's a good idea to have your whole-home surge protector tested by a qualified electrician. They can use specialized equipment to verify its effectiveness and ensure it's providing adequate protection. This is typically recommended every few years.
3. Replacement:
Lifespan: Whole-home surge protectors have a limited lifespan, typically ranging from 3 to 5 years, although some can last longer. Over time, the internal components can degrade, reducing their ability to protect against surges.
After a Major Surge: If your home experiences a significant power surge, it's recommended to have the surge protector inspected and tested, even if it appears to be functioning normally. A large surge could have damaged the internal components, making it less effective in the future.
Important Notes:
DIY vs. Professional: While some basic visual checks can be done by homeowners, any testing or replacement of a whole-home surge protector should be handled by a qualified electrician. Working with electrical panels can be dangerous, and it's essential to ensure the job is done correctly.
Manufacturer's Instructions: Always refer to the manufacturer's instructions for specific maintenance recommendations for your particular surge protector model.
Your Electrical Panel Matters
An up-to-date electrical panel provides a stronger foundation for effective surge protection, ensuring that your home and its valuable electronics are better shielded from the damaging effects of power surges. Some benefits of an upgraded panel include:
