What is a Whole-House Surge Protector, and How Does it Work?
A whole-house surge protector is a device that is installed directly into your home's electrical service box, providing a defense line for your entire home. Unlike standard power strips, which only protect the devices plugged into them, a whole-house surge protector safeguards all electrical systems and appliances in your house. Here's a basic overview of its operation:
- Monitoring: The surge protector continuously monitors the electrical voltage flowing into your home.
- Detection: Upon detecting an abnormal spike in voltage, it instantaneously diverts the excess electricity away from your home's electrical system.
- Protection: By sending the surge to the ground, it prevents the excessive voltage from reaching your connected devices and appliances, thereby preventing potential damage.
It's essential to understand that while whole-house surge protectors are incredibly effective, they're not foolproof. In the case of extremely powerful surges, like those from direct lightning strikes, additional layers of protection may be necessary. Therefore, combining whole-house surge protection with point-of-use surge protectors for high-value or sensitive electronics is always a good idea.
