The groove has a pair of low-voltage conductors embedded in the opposite side walls thereof to extend lengthwise of the groove, and accessible from the interior of the groove to provide electrical contact with an accessory which is inserted into the groove and moved into contact with the conductors. The conductors at one end of the groove, or at one end of a plurality of shelf units which are serially connected together, are joined to a suitable flexible electrical connector which joins to a conventional transformer plug for engagement with a conventional electrical outlet.
