An electrical service assembly is secured to a framework of a panel of an office partition system and includes at least one bracket to which at least one electrical outlet module is mounted, the module having at least a pair of electrical outlets such that electrical outlets may be positioned in a back-to-back configuration. In this manner, the electrical service assembly provides service to opposite sides of a panel that face opposite work spaces. Also, the electrical outlet modules may be associated with separate circuits to prevent overload of the electrical service assembly.
