Common causes include loose wiring, a failing meter, or issues with the electrical service entering your home. Symptoms may also include flickering lights, power surges, or an unusually high electricity bill. If your meter is making a buzzing noise, it's best to have an electrician inspect it as soon as possible to identify and fix the underlying issue.
