A furniture system including at least one furniture element having at least one raceway and a modular electrical wiring system at least partially located in the raceway. The electrical wiring system includes a plurality of wire distribution assemblies, an electrical assembly and an electrical switch. The plurality of wire distribution assemblies includes a first wire distribution assembly and a second wire distribution assembly. The electrical assembly partially electrically connects the first wire distribution assembly and the second wire distribution assembly. The first wire distribution assembly has a first number of electrical conductors. The electrical assembly is electrically connected to a second number of electrical conductors of the first wire distribution assembly, the second number being smaller than the first number. The electrical switch is configured to electrically connect a first electrical conductor of the first wire distribution assembly that is a member of the second number of electrical conductors to a second electrical conductor of said first wire distribution assembly that is a member of the first number of electrical conductors and not a member of the second number of electrical conductors.
