Frequently Asked Questions
Do I still need plug-in surge strips if I have a whole house protector?
Yes, you absolutely do. Think of a whole house protector as your first line of defense that handles the heavy lifting from external surges. Smaller plug-in strips provide a secondary layer of protection against surges generated by appliances inside your own home.
Will a whole house surge protector protect my home from a direct lightning strike?
It will significantly reduce the risk, but it cannot guarantee total immunity from a direct hit. Lightning carries an immense amount of energy that can overwhelm almost any standard protective device. It is designed to mitigate transient surges rather than catastrophic, direct atmospheric strikes.
How often do I need to replace a whole house surge protector?
Most units last for many years, but they do have a limited lifespan. If your unit takes a major hit, the internal components may be fried, requiring a replacement. Check your indicator lights monthly to ensure the device is still functioning correctly.
Can I install this device myself?
Only if you are a licensed electrician or very confident working with high-voltage electrical panels. Installing these devices requires removing the panel cover and connecting wires to live terminals. The risk of electrocution is real, so hiring a pro is usually the smarter choice.
Does the size of my electrical panel matter?
Most surge protectors are designed to be universal and fit into standard residential breaker panels. However, you should check your panel brand and available space before buying. Some units require two adjacent slots, while others can be mounted on the side of the box.
