A load control system having a controllable electrical outlet provides a low cost solution for controlling a plurality of standard electrical outlets. The controllable electrical outlet may be coupled in series between a power source and at least one standard electrical outlet for controlling the power delivered to the standard electrical outlet. The controllable electrical outlet may comprise an actuator for allowing the controllable electrical outlet to be associated with an input device for receiving digital messages from the input device. The controllable electrical outlet may be installed in a standard electrical wallbox, e.g., replacing a previously-installed standard electrical outlet. The actuator may be easily accessed to associate the controllable electrical outlet with the input device and a radio-frequency receiver and antenna may be located in the controllable electrical outlet to provide optimum reception of radio-frequency signals.
