A system for controlling access to a source of electrical power. The system includes a readable access information device with access information that is associated with an electrical load device electrically connectable to a receptacle, a switch device for connecting and disconnecting the receptacle to and from the source of electrical power, and a reader for reading the access information from the readable access information device, and determining whether preselected criteria are satisfied by the access information. If the preselected criteria are satisfied, the receptacle is connected to the source of electrical power, and the electrical load device is connectable to the source of electrical power via the receptacle. If any one or more of the preselected criteria are unsatisfied, then the receptacle is disconnected from the source of electrical power.
