Why is there a noise coming from the electrical box after turning off the main breaker?
There should be no noise caused by loose electrical connections if the main breaker is off. The only places that are energized at that point are the main lugs. There is nothing running so there shouldn't be any current which is the only reason a loose connection can cause noise.
But all that is based on what SHOULD be happening. If someone has tied into the mains to feed something then there could be noise caused by loose connections. Another possibility is something mechanical causing the panel to vibrate. Tightening the mounting screws might be sufficient to solve this problem.

What is the function of spacer in electrical transformer?
Spacers insulate the transformer tank from the mechanical vibrations of core & the windings.this results in reduced noise emisions.
What is the voltage level of noise signal?
Electrical noise amplitude depends on:1. source impedance, and2. Bandwidth.Approximately, at 50 ohms, you get around one nanovolt with one hertz bandwidth, increasing at the square root of frequency, at the square root of impedance.
Why does the breaker make a buzzing noise when turned on?
The breaker makes a buzzing noise when turned on because of the electrical current flowing through it, causing the internal components to vibrate and produce the sound.
Why does gould breaker box make buzzing noises?
