What is the terminology for sockets installed in the floor?

Floor sockets, alternatively termed as floor outlets or floor boxes, serve as indispensable electrical components seamlessly incorporated within flooring surfaces. 

These fixtures present a harmonious resolution for accessing electricity devoid of any visible wiring obtrusion or the inconvenience associated with utilizing extension cords. Predominantly situated in environments where conventional wall-mounted outlets prove impractical or inaccessible, such as conference rooms, corporate offices, and sprawling open-plan areas, floor sockets offer a subtle yet highly effective method for powering an array of devices and machinery. 

Their inconspicuous design ensures effortless integration into the floor, preserving both aesthetic elegance and practical functionality across a diverse spectrum of settings.
