Are you experiencing flickering lights often? 

 

Experiencing frequent light flickering can be an indication of an underlying electrical problem. It is crucial to address such issues promptly, as some of the causes can pose potential hazards. Electrical fires pose significant risks, leading to both life-threatening situations and billions of dollars in damages annually. By taking action early on, you can save yourself from unnecessary expenses and inconvenience.

 

Below are common reasons behind light flickering and their explanations:

  1. Change in Voltage: If you notice flickering lights after plugging in an appliance, it may be due to the appliance drawing a high amount of current at once. Typical home electrical systems operate at 200 amps, and when large appliances consume substantial power, it can cause momentary voltage fluctuations. If flickering occurs consistently when using appliances, it is advisable to have your home's electrical system evaluated to ensure it can handle your family's needs.

  2. Loose Bulbs: Improperly screwed light bulbs can result in flickering. If a light is not functioning correctly, try turning it off, allowing it to cool, and then securely screwing it back into place. This is a relatively simple issue that you can resolve on your own.

  3. Loose Connections: Loose connections are the most common and concerning cause of light flickering, as they have a high potential for causing fires. It is crucial to ensure that electrical connections are tightly secured to minimize resistance. Even with very low resistance, overheating can occur, leading to wire and connection damage, and potentially starting a fire. Loose connections can include loose wires, terminals, or breaker connections. It is always recommended to address loose connections promptly and seek professional assistance to rectify the problem.

  4. Light Type: Fluorescent light bulbs can occasionally flicker when used in residential settings. This occurs because the bulbs are controlled through an inductive ballast, and disruptions in power supply can lead to flickering. If you experience flickering with fluorescent light bulbs, it is important to note that it is not normal behavior. Contacting a professional electrician can help identify the cause and resolve the issue effectively.

 

Remember, when it comes to electrical concerns, prioritizing safety and seeking professional assistance is crucial. If you encounter flickering lights or any other electrical issues, it is advisable to consult an electrician promptly to ensure proper evaluation, diagnosis, and resolution of the problem.
