A junction box is a container used to house electrical connections, where multiple wires meet and are joined together. It helps to protect the connections from damage and prevents electrical hazards such as short circuits or fires. Junction boxes are typically made of metal or plastic and are installed in walls, ceilings, or floors. They are designed to be accessible for maintenance or repair, ensuring that wires remain secure and properly insulated. The box also helps to contain sparks or heat that may occur during electrical faults.
