Common Signs of Faulty Wiring

Frequent Circuit Breaker Trips

If your circuit breaker trips frequently, it could be a sign of faulty wiring. Circuit breakers are designed to protect your home by cutting off the electrical flow when the system is overloaded. Frequent trips indicate a potential issue that requires attention.

Flickering or Dimming Lights

Lights that flicker or dim unexpectedly can indicate a wiring problem. This might be due to loose connections or overloaded circuits. It's essential to address these issues promptly to prevent further complications.
