It is a stop-everything, do-not-flip-that-breaker situation. I’m Chris, and on behalf of , let me walk you through exactly what’s happening inside that box — and what to do before you touch anything. ## Why Water and Your Panel Are Such a Dangerous Combination Your electrical panel is the nerve center of your home. It controls every circuit, every breaker, every load. When water gets in — whether from a monsoon-driven roof leak near McCormick Ranch, a burst supply line in a North Scottsdale laundry room, or pooling in a garage after a flash flood — it does two things fast: - **It creates an immediate shock hazard.** Energized components and standing water is a lethal combination. Touching a wet panel — even to “just reset a breaker” — puts you at real risk. - **It starts a slow-burn corrosion process.** Moisture accelerates oxidation on bus bars, breaker contacts, and wiring terminations. That corrosion creates resistance, and resistance generates heat. Over weeks or months, that hidden heat becomes a fire risk. The tricky part? The panel might look fine from the outside. It might even function normally for a while. That false sense of security is exactly what makes [thermal imaging diagnostics so valuable after water intrusion](https://fhrelectric.com/what-thermal-imaging-finds-inside-your-walls-that-a-visual-inspection-misses/) — a visual check simply cannot see what corrosion is doing inside the enclosure or behind the walls. ## What to Do Right Now (Before You Call Anyone) ![A licensed electrician using a thermal imaging camera to inspect a residential electrical panel for water damage to electrical panel components](https://fhrelectric.com/wp-content/uploads/2026/08/avathan-6a8d6d87a52c7.jpg "Water Got Into Your Electrical Panel — Do Not Touch It Until You Read This") 1. **Do not open the panel or touch any breakers.** If the panel is visibly wet or you suspect water inside, treat it as energized and dangerous. 2. **If it is safe to do so, kill power at the meter main or exterior disconnect** — not at the panel itself. If you are not certain where that is or whether it is safe to access, leave it alone. 3. **Ventilate the space.** Open doors and windows near the panel area to begin drying the surrounding environment — but again, do not open the panel enclosure. 4. **Document everything.** Photograph the panel exterior, the water source, and any visible damage. Your homeowner’s insurance will want this, and so will we. 5. **Call a licensed electrician immediately.** Not tomorrow. Not after the weekend. Now. > A wet panel that “seems fine” is the electrical version of a check-engine light you keep ignoring. The problem does not go away — it just gets harder to see until it is not. ## What a Licensed Electrician Actually Does After ![A licensed electrician using a thermal imaging camera to inspect a residential electrical panel for water damage to electrical panel components](https://fhrelectric.com/wp-content/uploads/2026/08/avathan-6a8d6d922ca8c.jpg "Water Got Into Your Electrical Panel — Do Not Touch It Until You Read This") When our team at responds to a water-in-panel call across or anywhere in Maricopa County, here is what a proper assessment looks like — because this is not a job where guessing is acceptable: - **De-energize and open safely.** We coordinate with APS or SRP to pull the meter if needed, then open the enclosure under controlled conditions. - **Inspect bus bars, breakers, and lugs** for corrosion, arc damage, and moisture residue. - **Thermal imaging scan** of the panel and adjacent circuits — because heat signatures reveal what eyes cannot. This is the step most one-truck operators skip. - **Check flood-damaged wiring** at circuits that feed areas reached by water. Submerged or soaked wire insulation degrades, and those circuits need testing before they are re-energized. - **Determine repair vs. replacement.** Sometimes a thorough dry-out and component replacement is sufficient. Other times — especially in an older panel — [the panel has already reached the end of its service life](https://fhrelectric.com/how-long-does-an-electrical-panel-actually-last/) and this event is the moment to replace it properly. Panel replacement in typically runs anywhere from a few hundred dollars for targeted component work to $2,500–$5,000+ for a full panel upgrade, depending on amperage, permit requirements, and existing infrastructure. We quote it straight — start to finish — before any work begins. No surprise invoices. If you have an older panel — think 20 or 30 years, which is common in established neighborhoods near Old Town or along Shea Boulevard — water intrusion is also your signal to ask about [whether your panel is actually up to code](https://fhrelectric.com/is-your-breaker-panel-actually-up-to-code-or-just-passing-a-visual-glance/). A lot of them are not, and a lot of homeowners do not know until something forces the inspection. ## This Is Not the Job for an Unlicensed Handyman We hear it all the time after a flood event in Gilbert, Tempe, or Chandler: someone hired a handyman to “dry it out and check it over,” the handyman said it looked fine, and six months later there was a fire or a failed inspection. The [risks of hiring an unlicensed electrician in Arizona](https://fhrelectric.com/the-real-risks-of-hiring-an-unlicensed-electrician-in-arizona/) are real and well-documented — and post-flood panel work is exactly the scenario where those risks become catastrophic. is the electrical division of FHR Construction — a licensed, insured Arizona contractor with over 20 years in the Phoenix metro.
