What Is a Power Surge?

A power surge is when the normal amount of power flowing through an outlet suddenly increases. Usually, there are 120 volts of power flowing through a standard wall outlet, but the voltage can shift between 0 and 169 volts. When the voltage suddenly surpasses 169 volts, this is known as a power surge or a transient voltage.

Sometimes, small power surges happen without you knowing, which can gradually reduce the performance and lifespan of your electronic devices and appliances. In these cases, don’t hesitate to contact the electricians at LimRic for a preventative electrical system inspection.

What Causes a Power Surge?

A power surge can happen in your home when a current of electricity passes through an electrical device that exceeds its normal operating range. This surge of power can cause an electric arc and heat that can damage or destroy electrical wiring and other components.

Here are a few of the most common causes of power surges:

Electrical Overload

A common cause of power surges is an electrical overload, which is when there is an increase in power drawn from a single circuit. This excess power, followed by a voltage spike, usually occurs when you overuse extension cords or have too many devices or appliances plugged into the same circuits. Some electronic devices that often cause electrical overloads include space heaters, hair dryers, power tools, HVAC units, and large appliances.

Faulty Wiring

Damaged, exposed wires or outdated electrical systems can also cause power surges. But it can be hard to tell when wiring is faulty since it’s often located behind walls.

Some signs of bad wiring are:

Scorched marks on outlets
A burning smell or buzzing sound coming from outlets
Frequently tripping circuit breakers

If you notice these signs, you should disconnect any electrical devices, turn off power to the area, and contact a licensed electrician right away.

Lightning Strike

Lightning strikes are an indirect cause of power surges. Lighting can hit power lines, delivering large amounts of voltage and forcing the system to bear this drastic increase in electrical current. This triggers a huge power surge, which is why all devices without surge protection should be unplugged during severe thunderstorms.

Power Outages/Blackouts

Large-scale power grid failures can cause power outages or blackouts, and power surges can happen when electricity is restored. A sudden jump in current can occur, which can damage any device that is plugged in and does not have surge protection.

Whole Home Surge Protection FAQs

Do whole-house surge protectors really work?

Yes, whole house surge protectors are effective when they are installed correctly at the main electrical panel. These devices divert excess voltage from power surges to ground before it can reach sensitive circuits. Whole home surge protection helps safeguard appliances, HVAC systems, computers, smart TVs, and other electronics from surges caused by lightning, power grid fluctuations, and large motors cycling on and off inside the home.

Do I need an electrician to install a whole-house surge protector?

Yes, you should use a licensed electrician for whole home surge protection. These devices connect directly to your main electrical panel or service disconnect and must be wired to the correct breaker or lugs. A LimRic electrician will size the surge protection device, verify grounding and bonding, and make sure the installation meets the National Electrical Code and local Charleston requirements so your panel and connected circuits are protected.

What should never be plugged into a surge protector?

High power appliances such as refrigerators, freezers, space heaters, window air conditioners, and microwave ovens should not be plugged into a plug strip surge protector. These loads can overload the strip and create a fire risk. Instead, they should be plugged directly into properly grounded wall outlets. For broader protection of these large appliances, whole home surge protection at the main panel is recommended in addition to any point of use devices.

Do you need a permit to install a whole house surge protector?

In many areas, a permit is required when whole home surge protection is added to the main electrical panel, especially if new breakers or wiring changes are involved. Local building departments follow the National Electrical Code and may require a licensed electrician to install panel mounted surge devices from brands such as Square D, Siemens, or Eaton. LimRic can confirm permit requirements for Charleston and handle any necessary inspections as part of the installation.

Where should a whole house surge protector be installed?

A whole house surge protector should be installed at or inside the main electrical panel, also called the service panel. Mounting the device as close as possible to the main breaker and neutral/ground connection gives it the best chance to clamp down surges before they reach branch circuits. With whole home surge protection at the panel, all connected circuits, appliances, and smart home devices receive a first layer of protection from voltage spikes caused by lightning, power grid issues, or internal surges.
