How to Prevent Power Surges in the Home

What Is a Whole-Home Surge Protector?

A power surge is a sudden spike in voltage coursing through the home's electrical systems. The normal voltage is 120 volts in most homes, with a maximum of 169 volts, but the voltage rate climbs substantially during a power surge. This rapid voltage increase sends too much electricity through the system and all powered gadgets, damaging various appliances and even the risk of fires.

Many homeowners associate power surges with natural events, like a lightning strike when it occurs. But the truth is that the causes of power surges and how they happen vary. Aside from lightning, here are some of the most common causes of power surges:

  • Downed power lines
  • Bad wiring
  • High power demand
  • Appliances switching on and off

A surge protector is one of the least expensive and easiest ways to deal with power surges at home. 

Why Are Power Surges Dangerous?

surgesWhen the current in the electrical system spikes radically, power surges occur. While they only last a fraction of a second, they can destroy any outlets or plugged-in appliances. However, homeowners may not understand the risks. Some of the other impacts of a power surge include: 

Faulty Wiring 

Faulty wiring is a potential cause of power surges. Faulty wiring might be challenging to spot, especially if hidden behind walls. The following are signs of a defective wiring condition:

  • Visible burn marks or burning smell from outlets
  • Buzzing sounds from outlets
  • Circuit breakers tripping frequently
  • Flickering light

It's best to contact a qualified electrician if faulty wiring is noticed.


Lightning is the least common cause of power surges, but it can be the most devastating. A lightning strike can easily damage a home's electrical system, causing it to explode or destroy appliances.

Power Outage

Large-scale power system failures are the most common source of power outages. While the lack of electricity rarely causes problems, the reconnection can. After a power loss, the rapid increase in current can cause a power surge, potentially damaging various appliances.

Electrical Overload

As the name implies, electrical overloads occur when a lot of power is drawn from a single circuit. A power surge can happen when too many appliances are plugged in and extension cords are overused; the extra energy required may cause the overburdened course to receive a massive amount of current.

How Whole House Surge Protectors Help

Whole house surge protectors are connected to the home's electrical service box and can be used to protect things like TVs, computers, and other appliances. Some of the other benefits include: 

  • Protect high-tech gadgets
  • Transient surges protection
  • Prevent damage to appliances and devices
  • Electrical fire prevention
  • Suit the home's power needs
  • Protects the whole house
  • Suitable for all voltage currents.
  • Protects against internal surges
  • It's cost-effective

Does An Old Surge Protector Need Replacement?

A whole-house surge protector warranty is between 2 to 5 years. Therefore, if the surge protector has passed its warranty, it's time to consider a whole-house surge protector replacement.

Here are signs that a surge protector is ready for a replacement or repair:

  • It keeps turning off and on
  • Plugged in but not working
  • It's not grounded
  • Feels hot
  • Smells of burnt plastic
