    Abstract
    A power strip is providing including a housing coupled to a first end portion of a power supply cord, the housing having an electrical receptacle mounted thereto and connected to the power supply cord, the power supply cord having a second end connectable to a power source. A current sensor is coupled to the power supply cord between the electrical receptacle and the second end for detecting electrical current flow through the power supply cord and providing an output signal that varies in proportion to the current flow through the power supply cord. A processing circuit coupled to the output of the current sensor includes a display device for displaying at least one of the current, voltage, power, and phase associated with the power supply cord at the current sensor. The display device can be remotely coupled to the power strip for positioning the display in a convenient location.

    A polyphase power distribution and monitoring apparatus having sets of outputs for each phase of power and monitors for each phase of power disposed in the housing. Each monitor provides a visible display of current for an associated phase of power and an audible alarm for each phase of power if the current exceeds a predetermined value or falls below a predetermined value. In three-phase wye power systems, the apparatus preferably includes a neutral line monitor, including a neutral line curren...

    A load management system provides an interface between a power input and several switched power outputs and un-switched power outputs. A controller groups the switched power outputs into one or more load groups based on a switched current limit determined for the system and the measured currents of the electrical loads. The load groups are defined so that the sum of electrical load currents in each load group does not exceed the switched current limit. The controller also activates one or more s...
