FAQ

Basic Understanding

Q: What exactly does a surge protector do?
A: A surge protector monitors incoming voltage and diverts excess voltage to the ground line when it exceeds safe levels, protecting connected devices from electrical damage. It acts as a barrier between your electronics and potentially harmful power fluctuations.
Q: How do I know if my surge protector is still working?
A: Most surge protectors have indicator lights showing protection status. A green light typically means protection is active, while no light or a red light suggests replacement is needed. However, some damage isn’t visible, so regular replacement is recommended.

Installation and Usage

Q: Where should I place a surge protector?
A: Install surge protectors as close to the power outlet as possible, avoiding daisy-chaining. Keep them away from heat sources and ensure proper ventilation. For optimal protection, consider using them at each point where valuable electronics are connected.
Q: Can I use a surge protector with high-power appliances?
A: While surge protectors can handle most electronics, high-power appliances like air conditioners, heaters, or refrigerators should be plugged directly into wall outlets. Check the amperage rating of your surge protector and ensure connected devices don’t exceed it.

Maintenance and Replacement

Q: How can I maximize my surge protector’s lifespan?
A: To extend your surge protector’s life:
  • Avoid overloading it with too many devices
  • Keep it clean and dust-free
  • Check indicator lights monthly
  • Replace after major surges
  • Follow manufacturer maintenance guidelines
Q: What’s the difference between UPS and surge protection?
A: A surge protector guards against voltage spikes, while a UPS (Uninterruptible Power Supply) provides both surge protection and battery backup power during outages. UPS units are typically more expensive but offer comprehensive power protection.
