What might cause a flickering light in a residential setting?

A flickering light in a residential setting can often be attributed to loose connections or overloaded circuits. Loose connections may result from poor wiring practices or the gradual loosening of connections due to vibrations or temperature changes. These loose connections can create intermittent contact, causing the light to flicker.

On the other hand, overloaded circuits occur when too many devices draw power from a single circuit, exceeding its rated capacity. This can cause fluctuations in voltage supply, leading to dimming or flickering of lights. Ensuring that connections are secure and that circuits are not overloaded helps maintain a stable electrical supply to the fixtures, eliminating flickering issues.

While high energy consumption from appliances, unsuitable bulb wattage, and the use of too many extension cords can contribute to electrical issues, they are less directly linked to the specific symptom of flickering lights compared to the consequences of loose connections or overloaded circuits.
