What to Do If Your Surge Protector Failed During a Storm in St. Louis

Unplug the failed surge protector from the wall, switch off and disconnect all devices plugged into it, avoid touching any damaged parts, and contact a licensed electrician to inspect your home’s wiring and install a new, properly rated surge protector.

 

Immediate Actions to Protect Yourself and Your Home

 

When a surge protector fails during a storm, your first priority is safety. Follow these steps:

  • Unplug the surge protector from the electrical outlet. Removing power prevents sparks or further damage.
  • Switch off and disconnect every device that was plugged into the protector. Sensitive electronics can be harmed by leftover voltage.
  • Avoid touching any scorched or melted parts with bare hands. Use insulated gloves if you must move the device.
  • Keep children and pets away from the area until it’s cleared and safe.

 

Inspect and Document the Damage

 

Once the immediate danger is addressed, look over the surge protector and nearby wiring:

  • Check for burn marks, melted plastic, or a strong odor—signs the internal components failed.
  • Look at outlets, plugs, and extension cords for discoloration or warping.
  • Take clear photos of all damage for insurance or warranty claims.
  • Note the time and storm conditions, especially if you live in St. Louis, where severe weather is common.

 

Understand What a Surge Protector Does

 

A surge protector is a device filled with metal‐oxide varistors (MOVs). When voltage spikes above a safe level, MOVs divert excess electricity away from your electronics:

  • Clamping voltage: The threshold at which the MOV lets extra current pass to ground. Lower numbers mean better protection.
  • Energy absorption (joules): Indicates how much energy the unit can handle before the MOV burns out.
  • Once the MOVs wear out, the protector can no longer divert spikes, and it may fail silently or show visible damage.

 

Replace with the Right Equipment

 

After inspection, you’ll need a new surge protector suited to your needs:

  • Choose a model with at least 2,000 joules of energy absorption for home electronics.
  • Pick a low clamping voltage (around 400 V to 500 V) for better safety.
  • Look for a unit with a warranty that covers connected devices if the protector fails.
  • Consider protecting phone lines, cable-TV lines, and network cables if they run nearby.

 

Consider Whole-House Protection

 

Plug-in surge protectors guard individual outlets, but a whole-house surge protector mounts at the service panel. Benefits include:

  • Blocking large surges at the meter before they enter home wiring.
  • Protecting major appliances, lighting, and hard-wired systems.
  • Working together with point-of-use protectors for layered defense.

 

When to Call a Professional

 

If you notice severe damage, sparks, or believe the wiring was affected, never attempt major electrical work yourself. Contact a licensed electrician to:

  • Test your home’s grounding system and circuit breakers.
  • Verify outlet wiring integrity and correct any loose connections.
  • Install a proper surge protection strategy—both at the service panel and at key outlets.
  • Ensure compliance with local codes, whether you’re in St. Louis or Nashville.

 

Dealing with Insurance and Warranties

 

Electrical damage from storms is often covered under homeowners insurance. To file a claim:

  • Submit photos and descriptions of the failed surge protector and any damaged devices.
  • Provide proof of purchase or installation costs for new equipment.
  • Get a written report or invoice from your electrician detailing necessary repairs.

 

Preventing Future Failures

 

To minimize risk moving forward:

  • Regularly inspect surge protectors for warning lights or age-related wear.
  • Replace protectors every 3–5 years or after a major surge event.
  • Use only UL-listed devices and follow manufacturer instructions.
  • Install a whole-house protector as the first line of defense.

 

Final Checklist

 

  • Unplug and power down damaged equipment immediately.
  • Document and photograph all damage for records.
  • Replace the protector with the correct joule rating and clamping voltage.
  • Hire a licensed electrician to inspect wiring and install whole-house protection.
  • File any necessary insurance claims with full documentation.
  • Carry out regular maintenance and timely replacement of surge protection gear.

 

Following these steps will help you safely recover from a surge protector failure during a storm and strengthen your home against future power spikes. If you’re in St. Louis or nearby areas, professional support is available to ensure everything is done correctly and safely.
