All wire splices must be contained within a junction box for a building to meet electrical code, although sometimes splices are missed and may present hazards as a result. Any exposed wiring can be dangerous, but exposed wire splices are especially prone to accident because they can be tripped over, expel sparks or misrepresent themselves be misperceived as playthings by children or pets. Junction boxes are helpful for wire splices because they also allow one to easily locate the wire splice area.
