What is a Power Surge?

Simply put, a power surge is an incredibly brief, but incredibly powerful, jolt of electricity that can be sent through your home for a variety of reasons. When a power surge occurs, anything connected to your home’s electricity is at risk of being fried. Appliances, electronics, and your home’s wiring can all be damaged or destroyed in a few millionths of a second. Or worse, a house fire can be started.

Main Causes of a Power Surge

There are a number of different circumstances that can lead to a power surge in your home. Some of them are preventable, while others are generally beyond our control.

Certain Electronic Devices

Appliances in the home that draw a lot of power, such as air conditioning units, refrigerators, and other motor-powered devices are often the cause of power surges. However, that doesn’t mean that certain smaller electronics, such as hair dryers, can’t cause issues, either.

Faulty or Old Wiring

If your home has been wired improperly, or your wiring has worn down over time, it may cause a power surge. Keep an eye out for burning smells, buzzing sounds, and circuit breakers being tripped with unusual frequency.

Overworked Outlets 

The outlets in your home can only handle so many appliances and electronics at once. If you’re overworking any of your outlets or circuits you may cause a power surge or even an electrical fire.


A lightning strike can cause a devastating power surge in your home that can damage or destroy every appliance and electronic that is plugged into a power source at the time. Strong winds can also send tree branches into power lines, causing a serious power surge, as well.

How Does a Whole-Home Surge Protector Work?

A whole-home surge protector is a small device that is connected directly to your home’s service panel in order to limit the amount of voltage that is supplied to the outlets in your home in the event of a power surge. When a power surge occurs, a surge protector is designed to either block the flow of excess electricity into your home or short it into the ground. Certain units will have indicators that let you know a short has occurred, such as lights or alarms.

Whole-home surge protectors are generally rated to prevent surges anywhere from 40,000 to 100,000 amps, but that does not mean they are able to stop surges entirely. While the amount of excess electricity that your surge protector might allow through is unlikely to cause serious damage, it is always wise to have circuit protectors plugged into any high-use outlets in your home.

What is the Installation Process?

While the process of installing a whole-home surge protector is not overly complicated, it is most definitely something that requires the help of a licensed professional, as making any adjustments to the power in your home can be dangerous if not deadly when handled by someone who is inexperienced. A licensed electrician can generally perform a whole-home surge protector installation in about two hours or less. They simply need to hardwire the device to your home’s electrical box and ensure that it is properly grounded.

Do I Need a Whole-Home Surge Protector? 

Whole-home surge protection is a simple and relatively inexpensive way to ensure that your home, your family, and all of your valuable appliances and electronics are protected in the event of a power surge. And with our jobs and our daily lives becoming increasingly more reliant on the use of various electronic devices, the usefulness of having whole-home surge protection is growing by the day. It should be a no-brainer for any Medfield homeowner to take whole-home surge protection into serious consideration.
