The invention is an apparatus comprising an electrically powered appliance with electrically conductive members mounted to the appliance that both support and supply electrical power to the appliance. The electrically conductive members comprise insulative housings with openings that fit over connectors attached to a wall. Both the housings and the connectors comprise electrical conductors. When the connectors are fitted inside the housings, the electrical conductors mate to provide electrical power to the appliance. Furthermore, the appliance is suspended from a wall to which the connectors are mounted. The appliance can be modular or have particular dimensions that allow it to function within an automated storage and retrieval system. Finally, the appliance may be fitted with an outlet to accommodate a detachable power cord.
