Abstract: A power distribution system, in particular a power strip, includes one or more modules. The module housing typically approximates the shape of a rectangular or triangular block. In a preferred embodiment, the module approximates a cube and provides six major surfaces, each approximately at right angle to its neighboring major surfaces. Preferably, one major surface provides a male plug, while each remaining major surface provides a single female electrical socket. Such a module is spatially compact, aesthetically and visually appealing, and relieves the excessive bulk of oversized plugs that would otherwise block access to one or more sockets. A single module offers a stand-alone socket adapter, while a plurality of compatible modules can be joined together to form an adjustable power strip. Modules can be distinguished, such as by color, to specify function or use, and compatible modules can be conveniently provided in a kit.
