The Strike You Never Hear About

The lightning that damages a house usually does not hit it. It hits a pole, a tree, or a line some distance away, and the surge rides in on the service drop or the cable line. There is no bang and no scorch mark, which is exactly why the damage gets attributed to a coincidence weeks later.

Damage Today Versus Damage in October

Storm damage arrives on two clocks. The immediate kind announces itself: a dead appliance, a circuit that will not come back, a garage door opener that does nothing. The slow kind is the one that gets misdiagnosed for months. A surge that does not destroy a component outright can degrade it, so a TV or a furnace board that took a hit in July gives out in September and nobody connects the two. The same is true of surge protection itself. A whole-home device is sacrificial by design, and it can absorb a hit that uses up most of its capacity while its indicator light still glows green. Pitted contacts inside a breaker or a contactor behave the same way, arcing a little more each cycle until the connection cooks. If several unrelated things in the house have failed since the last real storm, that pattern is the diagnosis. Call (865) 256-0876 and describe the sequence.

Tripped Main or Utility Outage

These look identical from inside a dark house and mean very different things. If the neighbors are dark too, it is the utility and there is nothing to check indoors. If your house alone is out, something on your side opened, and that is worth understanding rather than simply resetting.

What You Can Safely Check Yourself

Stop there. Do not pull the panel cover, do not reset a main that keeps opening, and do not touch anything standing in water or near a downed line. Behind that cover the service lugs stay energized whether the main is on or off, and there is no homeowner-visible diagnosis worth that. If the smell of burning plastic is in the air, cut power to that room if you can do it safely and call us. Our Farragut electrical repair calls start with exactly the observations above, so writing them down before you call saves real time.

Surge Protection Is Layered, Not Singular

A panel-mounted surge protective device is the first line, and it does the heavy work: it clamps the big transient coming in on the service before it distributes into forty branch circuits. What it cannot do is finish the job. A whole-home device lets a residual through, and it does nothing about transients generated inside the house when a well pump or an air conditioner compressor cycles. That residual is still more than a modern control board wants. Point-of-use protection at the electronics, the media rack, the office, the HVAC control, catches what gets past the panel. Neither layer replaces the other, and a house with only power strips has nothing standing between the service drop and the wiring itself. We size and install the panel device, verify the ground and bonding path it depends on, and point out which loads in the house deserve the second layer.

Generators and Transfer Switches During an Outage

Backup power changes the picture during a storm and introduces its own failure points. A properly installed transfer switch isolates your house from the utility before the generator picks up the load, which protects line crews and protects your equipment when utility power returns mid-cycle. That transfer moment is worth attention: an automatic switch sitting through repeated storm-season transfers can develop pitted contacts, and the symptom is a transfer that hesitates, chatters, or drops loads that used to ride through. Portable units carry the bigger hazard. A generator backfed through a dryer outlet energizes the utility side, which is genuinely lethal, and it also leaves your equipment exposed when the grid returns. If your standby unit exercised strangely after the last round of storms, that is worth a look before the next one.

Humidity, Exterior Receptacles, and East Tennessee Summers

Storms here are afternoon events, they stack up several days in a row, and they leave humidity behind that never really clears. That combination is hard on anything outdoors. Water gets past a cracked weather cover or a receptacle mounted without a proper in-use bubble cover, and then the humidity keeps the inside of that box damp for weeks. Corrosion builds on the contacts, resistance climbs at the connection, and the receptacle starts running warm before it fails. The pattern shows up on deck outlets, pool equipment, landscape lighting, and detached garage circuits more than anywhere else. If an outdoor GFCI has started nuisance-tripping on humid days, that is not a defective GFCI. That is the device telling you moisture found a path, and replacing it without correcting the enclosure just resets the clock.

When to Stop Investigating

Stop when you smell burning, when a breaker will not stay closed, when anything is warm to the touch, when there is water anywhere near electrical equipment, or when a line is down on the property. Stop also when the checking has told you what you need: half the house dark with the neighbors lit, or three unrelated devices dead since the same Thursday. Past that point the next step needs a meter, a thermal camera, and someone licensed to open the panel. We serve Farragut and the rest of Knox County out of Sevierville, we prioritize storm calls, and the electrician who diagnoses the problem is the one who repairs it.
