Abstract: A supply unit for supplying a workplace with electricity and/or gaseous media, with a first, vertically extending supply duct and a second, vertically extending supply duct, wherein the electricity and the media are led to connections on at least one of the supply ducts. From these connections the workplace is supplied and improved such that the ergonomically most favorable arrangement of the supply tubes and electric lines leading to the connections will be possible. This object is accomplished by a section of the side surfaces having an angle of inclination less than 90.degree. in relation to the base such that the ends of the side surfaces pointing away from the base can be connected at a common junction. The connections are arranged exclusively on the outer side surfaces and that the distance between the supply ducts is such that the workplace can be brought into the space between the supply ducts.
