What Does a Surge Protector Do?

Power surges can wreak havoc on your home’s electronics and appliances, often without warning. These sudden voltage spikes damage sensitive devices or render them completely unusable and can even cause an electrical fire. That’s why you should integrate surge protectors into your electrical system. Learn exactly what surge protectors do and how to choose the right one for your needs in Cleveland, Akron, or Brunswick, OH.

What Is a Power Surge?

A power surge occurs when a sudden and significant increase in the electrical voltage runs through your home’s wiring. Most homes operate on a steady 120 volts, but a surge briefly pushes that number far higher. Even small surges, called transient surges, can gradually degrade your devices. They’re undetectable and often go unnoticed until something breaks.

These surges may result from:

• Lightning strikes: A lightning strike near your home can send a massive surge through the electrical grid, overwhelming your system.
• Electrical overloads: Plugging too many devices into a single outlet or circuit can cause a surge, especially if those devices are high-power space heaters, microwaves, or hairdryers.
• Faulty wiring: Old or damaged electrical wiring can create unpredictable voltage spikes.
• Power restorations: When the power comes back on after an outage, the initial surge of electricity can overwhelm your home’s system.

How Does a Surge Protector Work?

A surge protector is the first line of defense for your electronics. Most surge protectors use a component called a metal oxide varistor (MOV). When a voltage spike occurs, the MOV detects and redirects the excess electricity away from your devices, protecting them from harm. Once the surge passes, the MOV resets, allowing normal electrical flow. It’s an effective yet simple way to ensure that only safe, stable voltage reaches your appliances and gadgets.

Types of Surge Protectors

There are two primary methods of power surge protection to suit different needs. The first option is to use outlet surge protectors. These devices plug directly into the wall, providing one or more surge-protected outlets designed to power devices like TVs, computers, and gaming consoles. It’s important to note that not all power strips guard against power surges. Look for the word “surge protector” on the packaging to ensure you’re buying the right gear. Though less common, you can also find surge protector wall outlets.

The other option is to install a whole-house surge protector within your home’s electrical panel. This investment protects every gadget and appliance in the house by stopping surges at the source before they reach individual outlets. The result is comprehensive protection for your entire home, including hardwired systems like your HVAC equipment and light fixtures.

How To Choose the Right Surge Protector

Now that you know how a surge protector works, you must decide which surge protection solution meets your needs. Outlet surge protectors are best for small households or renters who need protection for a few key electronics, such as a personal computer and home entertainment system. These point-of-use devices offer fast, affordable protection, but you may need more than one for complete coverage.

Then, whole-house surge protectors are best for homeowners who want peace of mind and comprehensive protection. If you’re looking to shield every electronic device and hardwired appliance in your home, a whole-house surge protector is the way to go. They’re especially important in areas prone to power outages or winter storms, like Northeast Ohio.

Ultimately, combining whole-house surge protection with outlet surge protectors offers the most robust solution for any home.
