JUNCTIONBOX
Junction box
An electrical junction box is a container for electrical connections, usually intended to conceal them from sight and deter tampering. A small metal or plastic junction box may form part of an electrical conduit wiring system in a building, or may be buried in the plaster of a wall, concealed behind an access panel or cast into concrete with only the lid showing. It sometimes includes terminals for joining wires. A similar container used for joining wires to electrical switches or sockets is called a pattress.The above text is a snippet from Wikipedia: Junction box
