It's important to recognize the warning signs that indicate your electrical system needs maintenance. These include:

• Flickering or dimming lights which can signal a loose connection or an overloaded circuit.

• Warm or humming sounds coming from electrical equipment, outlets, or circuit breakers.

• Burning smells or scorch marks around electrical panels and wiring.

• Frequent tripping of circuit breakers, which often indicates an overload or a short circuit.

• Visible wear and tear on conductors, insulators, and other hardware, such as corrosion, fraying, or physical damage.
