A managed electrical outlet includes a plurality of electrical receptacles, a current sensor, logic circuitry, a switch driver, and one or more switches. The electrical current provided to the managed electrical outlet is measured by the current sensor, which in turn sends an electrical signal to the logic circuit, representative of the amount of electrical current flowing through the outlet. The logic circuit compares the level of current flowing through the outlet with a reference current level to determine whether an over-current state exists. If the logic circuit determines the presence of an over-current state, the logic circuit sends a signal to the switch driver, causing the switch driver to trigger the switch into an open-circuit condition. In a two-receptacle outlet, one of the two receptacles is coupled to the switch while the other receptacle is unmanaged. Thus, in an over-current condition, current continues to be provided to the unmanaged receptacle while the managed receptacle (connected to the switch) is disabled.
