Frequently Asked Questions
Do I still need power strips after installing a whole house surge protector?
Yes, you absolutely do. A whole house unit acts as the primary defense against large spikes, but it cannot stop the small, frequent surges created by appliances inside your home. Using a point-of-use power strip at your computer or television provides the final layer of defense for delicate hardware.
Will these devices protect my home against a direct lightning strike?
They significantly reduce the risk, but no device can guarantee total protection against a direct lightning strike. Lightning carries millions of volts, which can easily overwhelm any standard residential safety equipment. These protectors are designed to mitigate the damage from nearby strikes and grid malfunctions.
How often do I need to replace a whole house surge protector?
Most units last between three to five years depending on the frequency of power events in your area. If your home experiences frequent brownouts or storms, you should check the status indicators annually. Once the protection light fails, the unit is effectively a paperweight and requires replacement.
Is a whole house surge protector the same as a circuit breaker?
They serve completely different purposes. A circuit breaker protects your wiring from overcurrent or short circuits that could cause a fire. A surge protector guards your electronics against sudden voltage spikes that travel through the utility lines.
How much should I expect to pay for a quality unit?
You can find reliable entry-level models for around $100 to $200. Professional-grade options that offer higher capacities and better warranties often range from $300 to $500. Factor in the additional cost of professional installation, which usually adds another one to two hours of labor to your bill.
