Is it dangerous if the electrical box makes a noise

A buzzing noise coming from your electrical panel, often called a fuse box or breaker box, should be treated with urgency because it represents an electrical fault that is abnormal and potentially hazardous. Letting the problem go unaddressed could lead to further complications and even pose a safety risk. A faint, low humming sound is sometimes a normal byproduct of alternating current (AC). While the device should operate silently, a distinct, sudden, or loud buzzing sound indicates a serious fault. Alternative current (AC) causes fluctuations in magnetic fields, and this causes vibrations. Most of the time, this isn't harmful, and only the higher voltage appliances will create an audible.
