When the Lights Go Out: How to Handle Power Surges

Lightning strikes, and before you can count to “one-Mississippi,” the thunder follows. Suddenly, the lights go out. Moments, maybe hours later, the lights turn back on. Though it is a familiar experience for many, our team at A-1 Electric can attest to the hidden damage and dangers that power surges can bring. Even small surges can damage your electronics over time. Faulty wiring poses a significant threat to homes and the families that live in them. That is why homeowners count on A-1 Electric for electrical inspections in Montgomery County and throughout Pennsylvania.

What Is a Power Surge?

A power surge is a sudden and unintended spike in voltage. This spike can easily harm or ruin sensitive electronic systems and appliances. A surge can at its gentlest wear away delicate circuitry over time; at its strongest, it can melt components and cause fires.

Lightning Strikes

Although many people have experienced power surges caused by lightning, it is actually not the most common cause. Such strikes are notable, though, for voltage spikes in the range of millions, with sometimes catastrophic results.

Switching of Power Grids

Perhaps even less frequently, utility companies can sometimes cause surges by initiating grid switches. Such switches are often done to help reset connections to customers after a tree limb or other disruption affects the customers’ access to power.

Appliance Operation

Surprisingly, the most common cause of power surges comes from turning large appliances on or off. Due to their high energy demand, changes in their functioning can cause disruptions to the steady flow of voltage. Though the surges might be small, they are often sufficient to damage electrical components over time.
