Frequently Asked Questions
Do I really need a whole-house protector if I already use plug-in strips?
Plug-in strips are like a secondary filter for your gadgets. They handle small spikes, but a whole-house protector stops the major surges from ever entering your electrical system. Using both provides the best defense for your home.
Can I install a whole-house surge protector myself?
Unless you are a licensed electrician, you should leave this task to a professional. Working inside a live electrical panel is dangerous, and improper wiring could lead to a fire hazard or void your warranty. It is worth the cost to have it done correctly.
How long will a surge protector last?
Most units last for several years, but their lifespan depends on how many surges they absorb. If your area experiences frequent lightning storms, you might need to replace the unit sooner. Keep an eye on those indicator lights to know when it is time for a swap.
Will a surge protector stop a direct lightning strike?
Even the best devices cannot guarantee total protection against a direct lightning bolt. They are designed to manage the massive energy surges that travel through power lines. Consider the device an essential layer of defense rather than an absolute shield.
What should I look for in a product warranty?
A high-quality protector often comes with a connected equipment warranty. This means the manufacturer will help cover the cost if your appliances are damaged while the protector is active. Always read the fine print to understand what is covered and what is excluded.
