Abstract
Abstract A furniture work surface such as a table top or desk top has a through hole in which is mounted a grommet. An electrical outlet box is insertable into the grommet without blocking the passage of the other wires that pass through the grommet to the work surface. The electrical housing has a recess which removably receives one of various receptacle modules, each receptacle module being configured to receive different circuits when fed by a multi-wire branch circuit.
