How can I reduce the risk of power surges in Greensboro, GA?

Home › Answers

Quick answer: Reduce surge risk in Greensboro, GA by using layered protection: install a UL 1449–listed whole-home surge protective device (SPD) at the service equipment, add quality plug-in surge protectors (or a UPS) for sensitive electronics, and correct underlying electrical issues like loose connections or improper grounding/bonding. During peak thunderstorm months and outages, unplug what you safely can and use properly installed transfer equipment for any generator—never DIY panel or transfer modifications.

Start with a whole-home SPD at the service (and choose the right type)

The most effective single upgrade is a panel/service-installed SPD that limits (“clamps”) high-energy, fast voltage spikes before they spread through branch circuits. For credibility and safety, look for a device that is listed to UL 1449 (the primary safety standard for SPDs in the U.S.).

Type matters and depends on where it’s installed:

• Type 1 SPD : intended for installation ahead of the main disconnect (often at the meter/service equipment), when allowed by the equipment and local requirements.
• Type 2 SPD : typically installed on the load side of the main disconnect—commonly at the main panel.

Which one fits your setup depends on your service equipment and manufacturer instructions. Code requirements and installation rules for SPDs are addressed in NEC Article 285 , and surge protection is also addressed for dwelling unit services in NEC 230.67 (adopted/modified by local jurisdictions). Always follow the SPD manufacturer’s installation guidance for lead length, breaker/fusing, and mounting location.

Layer protection at the outlets (and know when to replace plug-in protectors)

No single device stops every surge, so a practical approach is layered protection: the whole-home SPD reduces what enters the home wiring, and point-of-use protectors reduce the remaining surge energy right at electronics. Use plug-in SPDs (or a UPS for computers/network gear) for TVs, routers, gaming systems, and home office equipment.

Replace a plug-in surge protector when:

• The protection/ground indicator light is off or shows a fault (many units stop protecting even if they still pass power).
• It was exposed to a major event (nearby lightning, a significant utility disturbance, or a surge that coincided with equipment failure). When in doubt, replace it—plug-in SPDs are consumable.
• The unit is damaged (cracked housing, scorch marks, loose plug, burning odor) or runs unusually hot.

Reduce “internal surge” and damage risks: wiring condition, grounding/bonding, and warning signs

Surge damage isn’t only from lightning. Switching of large loads (HVAC, refrigerators, well pumps), utility operations, and loose/overheated connections can all contribute to voltage disturbances. A whole-home SPD works best when the electrical system is in good condition and properly grounded/bonded.

When to call an electrician (don’t wait):

• Buzzing/crackling at the panel, meter base, or receptacles
• Hot receptacles/switches , burning smell, discoloration, or scorch marks
• Repeated breaker trips (especially on the same circuit) or persistent flickering/dimming

What an SPD + grounding/bonding inspection typically includes:

• Confirming the service has an appropriate grounding electrode system and that grounding/bonding connections are intact and correctly landed
• Checking the panel for loose/overheated terminations , neutral/ground bar condition, and signs of arcing or water intrusion
• Verifying the SPD is correctly sized/located, properly connected, and installed per manufacturer instructions (including minimizing lead length where applicable)
• Reviewing whether sensitive or high-demand equipment needs dedicated circuits to reduce nuisance trips and overheating risks

Thunderstorm and outage habits that help (including generator safety)

During peak thunderstorm months , the safest low-tech protection for small electronics is to unplug them (power and any connected coax/Ethernet) if you can do so safely and before the storm is overhead. For many appliances you can’t “restart” manually, but you can avoid turning on large optional loads immediately after power returns and let systems stabilize for a few minutes.

If you use a portable generator during outages, do not attempt DIY grounding, panel, or transfer modifications. A generator must be connected with approved transfer equipment (transfer switch or interlock kit, as appropriate) to prevent dangerous backfeed onto utility lines and to protect your home’s electrical system. Transfer equipment and bonding/grounding must follow applicable code and manufacturer instructions.
