Most of the time, electricity flows through your home’s electrical wiring at a steady rate. Sometimes, that flow is interrupted and starts again, or something causes the electricity to spike. Known as power surges, these fluctuations are normal and are usually minor and barely even noticeable. There are times, though, when the surges are stronger and capable of causing significant damage to your home and appliances.

What Causes Power Surges? 

Power surges can be internal or external. Internal power surges are the most common and are actually imperceptible most of the time. Tiny spikes in power occur when you turn electronics on or off, and because most devices are designed to withstand these surges, they don’t cause any damage. 

That said, internal power surges can be dangerous or cause damage if you have faulty electrical wiring. You might notice a power surge when you turn on the air conditioner or blow dryer.

When this happens, you will typically notice that the lights flicker or dim for a moment because the power is being diverted. Sometimes, this surge in power will cause the breaker switch to trip, as the system automatically tries to protect itself from the spike by shutting down entirely.

Lightning strikes are a type of external surge, which can send enough electricity through the wires to actually “fry” your appliances. These surges often accompany power outages as well, as a surge of power comes through the electrical wiring all at once when the power is restored. 

How Can You Prevent Power Surges?

If you have a problem with internal power surges, even minor ones, you may need to upgrade your electrical wiring. Older homes, especially those built before 1980, are usually not designed to handle the load of modern appliances. Frequently tripped breakers, blown fuses, or dimming lights when you turn on appliances are a sign of inadequate wiring. 

Overloaded circuits can also cause power surges. If too many devices, or several devices with large power loads, are drawing on the same circuit, surges are likely. Having an electrician install circuits for each room, and multiple circuits where necessary (such as the kitchen) can reduce the risk of a surge. 

Finally, unplugging devices when they aren’t in use can prevent damage if there is a surge and reduce the amount of power used. Consider using a surge protector for larger items that can be easily switched off when not in use to prevent power spikes.
