A junction box is an enclosure that protects a connection of two or more wires carrying electrical current. This level of protection is needed to prevent fires and to maintain solid, reliable connectionsthat staytight over many years.
The use of junctions removes the need to run a wire from every outlet or switch back to the main service panel. It also makes it much easier to locate and repair any electrical problems that come up.
If some connections are made inside wall cavities or in hidden ceilings or attics, for example it can become difficult to find them. Every electrical connection should be inside a protective box that is easy to find and access.
Junction boxes can be used to connect additional sockets to circuits, add lighting points, extend circuits and in general are a way of getting power from an existing source and taking it somewhere else.
An electrical junction box can be made of either metal or plastic, and usually measure 2½ inches deep or 3½ inches deep, holding either three or five different wires, respectively.
The junction box serves as the communal meeting spot for electrical wires, where they connect before moving on. The cover protects the wires from being touched or knocked, keeps out dirt and dust, and prevents moisture from getting inside the box.
All junction boxes must be covered, installed correctly and in compliance with the applicable building codes.
DBI Control have been using Rittals range of Command Panels with handle strips for junction boxes in our recent projects, such as the CP 6315.400.
The CP 6315.400 is slightly larger than the usual measurement for junction boxes, as it measures 500mm x 500mm x 210mm. It is made out of sheet steel, is IP55 rated and a wall-mounted version is also available.
