How Surge Protectors Work
Surge protectors are essential devices that help safeguard your electronics from power surges, including those caused by electrical storms and lightning strikes. Understanding how surge protectors work can give you peace of mind knowing that your valuable devices are protected.
Surge protectors function by monitoring the voltage flowing through your electrical wiring. When a dangerous spike in voltage is detected, the surge protector acts as a barrier, diverting the excess energy away from your devices and into the ground through a grounding wire. This prevents the surge from reaching your valuable electronics and potentially causing damage.
There are different types of surge protectors available, including point-of-use surge protectors and whole-home surge protectors.
A point-of-use surge protector, commonly known as a power strip, is an affordable and convenient option for protecting individual devices. These surge protectors typically include multiple outlets and built-in surge protection capabilities. By plugging your devices into a power strip surge protector, you can ensure they are shielded from electrical disturbances.
On the other hand, whole-home surge protectors provide protection at the main electrical panel, safeguarding your entire home from power surges. Installed by a professional electrician, whole-home surge protectors work by intercepting and redirecting surges before they enter your home’s electrical system. This comprehensive protection is especially beneficial for homes located in areas prone to electrical storms and lightning strikes.
To maximize the effectiveness of surge protectors, proper grounding is crucial. Surge protectors rely on a solid ground connection to safely direct excess energy away from your devices. It’s important to ensure that your home’s electrical system is properly grounded to ensure optimal protection.
Additionally, it’s advisable to replace surge protectors every few years. Over time, surge protectors may become less effective in diverting excess energy, reducing their ability to protect your devices. By regularly replacing surge protectors, you can ensure that your electronics remain shielded against electrical storms and other power disturbances.
