M2 Modular Gang Box

An electrical Modular Gang box  is an enclosure housing electrical connections. Gang boxes protect the electrical connections from the weather, as well as prevent people from accidental electric shocks.

A small metal or plastic Gang Box may form part of an electrical conduit or thermoplastic-sheathed cable (TPS) wiring system in a building. If designed for surface mounting, it is used mostly in ceilings, under floors or concealed behind an access panel—particularly in domestic or commercial buildings. An appropriate type (such as that shown in the gallery) may be buried in the plaster of a wall (although full concealment is no longer allowed by modern codes and standards) or cast into concrete—with only the cover visible.

It sometimes includes built-in terminals for the joining of wires.
