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.
A noise generator produces electrical signals in both audio and video format. These are used for troubleshooting purposes in signal circuits for amplifiers and televisions.
Depending on the circuit, typically a combination of a coil (commonly called a choke) and a capacitor can be put in circuit at multiple places to significantly reduce noise in a circuit.
An in line device used in filtering ac votlage out of transient or (electrical noise) before allowing the electrical current to enter an electronic board of certain designs.
Spacers insulate the transformer tank from the mechanical vibrations of core & the windings.this results in reduced noise emisions.
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.
i have heard that noise and I believe it is coming from the body frame connection and i also heard that u can get a kit to eliminate the noise. Ed
Sounds like a defective breaker in the box, or a loose wire connection. Tighten connections at breakers, and neutral bus bar. Sometimes you can feel the breaker slightly vibrating, BUT ,be very careful!
The decibel noise level of a concrete breaker is at around 111 to 113. This can vary depending on what concrete breaker one is using, and might have a different noise level.
More detail is needed here, does it make a clicking noise, is there any feeling at all when turning key, do other electrical items work, etc.More detail is needed here, does it make a clicking noise, is there any feeling at all when turning key, do other electrical items work, etc.
Questioner gives no indication where the noise is coming from, but it COULD be an indication of a failing CV (constant velocity) joint.
It's probably an electrical problem. It could be the radiator or the alternator. Check the filter caps.
without more information i would say it sounds like the wheel bearing.
The clicking noise you are hearing could be the heater is overloading the breaker and it is on the verge of tripping This could be caused by the heater being to large for the circuit. Check the amperage rating on the heater and the rating on the breaker It also cold be the circuit breaker is going bad and needs to be replaced by a qualified electrician These are 2 possible answers you also could have a bad (loose) electrical connection some where in the circuit
This buzzing noise is likely a faulty wheel bearing. The bearings are moving around randomly and need to be replaced.

Joyful Noise is coming out on DVD in June 2012
The fuse box also contains breakers and relays.The clicking noise will be a relay clicking on or offMore serious cause:Or there is a breaker that is opening due to over load and resetting by itself. This is a very serious situation and may mean there is a short or other serious and dangerous electrical problem.
