5 Signs Your Electrical System Is Overheating This Summer (and What To Do About It)

Summer heat puts extra stress on your home’s electrical system. Air conditioners run nonstop, refrigerators work harder, and fans, dehumidifiers, and pool equipment all compete for power. When your system becomes overloaded or overheated, it can quickly turn into a fire hazard.

Here are the top signs your electrical system may be overheating—and what you should do to stay safe.

1. Breakers Keep Tripping More Often

If your breakers trip repeatedly during hot days, it usually means:

- Circuits are overloaded

- The breaker is overheating  

- Wiring is stressed  

Do **not** keep resetting it. Each trip is a warning sign.

2. Outlets or Switches Feel Hot to the Touch

Warm is normal.  

Hot is dangerous.

A hot outlet could indicate:

Turn off the circuit and call an electrician if heat is consistent.
