Frequently Asked Questions
Do I still need power strips inside my house if I have a whole house surge protector?
Yes, you should keep using point-of-use strips for sensitive electronics like computers and televisions. A whole house protector acts as a first line of defense, but it cannot stop every small spike or noise created by devices inside your home. Think of this as a two-layer security system for your electronics.
Can I install a whole house surge protector myself?
Only attempt this if you are comfortable working inside a live electrical panel and understand local building codes. Most municipalities require a licensed electrician to handle this job to ensure it meets safety standards. If you are not an expert with high-voltage wiring, hire a professional to avoid serious injury.
How do I know if my surge protector has failed?
Most modern units feature LED indicator lights on the front of the device. If the light goes out or turns red, the internal components have likely absorbed their maximum capacity and the unit needs replacing. Check these lights at least once every few months to ensure your home remains protected.
Will a surge protector protect my home from a direct lightning strike?
No device offers a total guarantee against a direct lightning strike. While these protectors effectively handle surges from utility switching or nearby strikes, a direct hit carries far more energy than any residential device can manage. These units are designed to minimize risk rather than provide absolute invincibility.
How long do these protectors typically last?
A high-quality unit often lasts for five to ten years depending on how many surges your local power grid experiences. Frequent power fluctuations will shorten its lifespan faster than a stable, reliable grid. Always keep your receipt and check the manufacturer's warranty for specific replacement timelines.
