A data acquisition system senses current and voltage from a common electrical circuit supplying a power to load branch circuits containing loads that undergo changes in load condition, such as starting and stopping. Transmitters connected to the load branch circuits identify the loads that undergo load condition changes. A data processor receives information from both the sensors and the transmitters to link the sensed current and voltage information from the common electrical circuit to the particular loads that undergo changes in load condition.
