Dimensional Drawing
Â
When a junction box is used for every electrical connection in a building it is much easier to locate and repair any electrical problems that come up.
When some connections are made without junction boxes, such as inside wall cavities or in hidden ceiling or attic locations, the likelihood future problems increases.
Every electrical connection should be inside a protective box that is easy to find and access.
