A metal or plastic box where electrical wires are joined together, kept accessible behind a removable cover.
An enclosed protective container where electrical wires are connected together, providing a safe and accessible location for wire splices. Junction boxes must remain accessible and cannot be buried inside walls or ceilings without a cover. They are sized based on the number and gauge of conductors they contain.
The electrician installed junction boxes at every wire splice rather than using wire nuts inside the wall cavity.
