The answer to 'what is junction box' is a junction box is an electrical box used to connect and house electrical wires and cables in a home or building. Junction boxes are typically square or rectangular metal or plastic boxes that are installed in walls, ceilings, or other locations to provide a safe and accessible place to join multiple electrical circuits together. They serve as a central point where wires can be spliced, connected, or routed to other electrical devices or fixtures.
