Typically a loose connection is either wires in a wire nut not making a proper connection, or a wire not tighten properly in a breaker and/or device e.g., outlet, switch, etc.
a loose connection of a neutral wire
If you get sparking in an electrical switch there is a loose connection or short in the circuit. The switch should be repaired or replaced.
Not usually. When a wire burns and grounds out the breaker will trip. Wire burns are usually centered around terminal connections points. If a connection becomes loose heat will be produced and this heating action is what burn the insulation on the wire. The neutral wire on the other hand is not switched so it is less likely to have terminal connection points that can become loose. In a circuit the neutral wire is connected under a wire nut with other neutral extensions in the circuit and then connected to the neutral buss in the distribution panel. There is very little to go wrong on the neutral return side of the load wire.
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.
Splices and termination are made in junction boxes because of safety. The weakest part of any circuit is the place where two or more wires are joined together. Because most home splices are of a mechanical nature they an become loose or just fall apart. A loose connection in a circuit that is carrying a high current will create heat through the resistance formed by the loose connection. Heat can cause combustion. Be retaining the heat or combustion in a closed container such as a junction box it contains the fault to a local area. Some electrical faults can create a shower of sparks that if not contained could cause the surrounding materials to ignite. Always keep the overs on junction boxes and never get into the habit of making open wire splices just because they work. Safety first.
You obviously have a loose connection. Trace the wiring and find the loose connection. GoodlluckJoe
connection.
Loose bulb or loose connection.
The wiring could be loose at a connection that feed the dash cluster. The fuse box could also have a loose connection.
loose connection may be thriiils to electric shock which is more dangerous so avoid the loose connections

Sounds like a loose electrical connection, possibly a loose ground connection.
Loose alternator belt, poor ground connection, or loose or corroded electrical connections. A loose ground is the most likely culprit.
