Frequently Asked Questions

#

What’s the difference between a surge protector and a power strip?

#

A basic power strip only provides multiple outlets with no surge protection. Surge protectors include MOVs (Metal Oxide Varistors) that absorb voltage spikes and protect connected equipment. Always choose surge protectors over basic power strips for valuable electronics.

How often should I replace surge protectors?

#

Replace surge protectors every 3-5 years, or immediately after a major electrical event (lightning strike, power outage). Surge protection degrades over time and with each surge absorbed. Many models include indicators that show when replacement is needed.

Can surge protectors protect against lightning strikes?

#

Surge protectors can handle typical electrical surges, but direct lightning strikes require whole-house surge protection installed at your electrical panel. For maximum protection, combine whole-house protection with individual surge protectors.

Do I need a surge protector if my building has surge protection?

#

Yes. Building-level protection guards against external surges, but internal surges from motors, HVAC systems, and other equipment still require point-of-use protection. Layered protection is most effective.

What’s the difference between surge protectors and UPS systems?

#

Surge protectors only protect against voltage spikes. UPS (Uninterruptible Power Supply) systems provide surge protection PLUS battery backup during power outages. UPS systems cost more but prevent data loss and equipment damage from power interruptions.

Should I plug my laser printer into a surge protector?

#

Most surge protector manufacturers recommend against plugging laser printers directly into surge protectors due to their high power draw. Use a dedicated outlet or a heavy-duty surge protector specifically rated for high-wattage devices.
