The answer to 'electrical meter making buzzing noise' is that a buzzing noise from an electrical meter is usually caused by a problem with the meter itself or the electrical system it's connected to. Common causes include loose connections, a faulty meter, or issues with the power supply.
If your electrical meter is making a buzzing noise, the first step is to check the connections to the meter and ensure they are tight and secure. If the connections look good, the issue may be with the meter itself. In this case, it's best to contact your local utility company, as they are responsible for maintaining and repairing electrical meters. Attempting to repair or tamper with the meter yourself could be dangerous and may even be illegal.
