A method for distributing electrical power to a plurality of electrical loads, the method comprising: coupling an existing group of electrical loads to a common power source through a load management system; measuring an aggregate group current drawn by at least the existing group of electrical loads and comparing the measured aggregate group current to an aggregate group current threshold value; when the measured aggregate group current exceeds the aggregate group current threshold value: increasing a number of subgroups of the existing group, using subgroups that are formed without requiring information about individual current associated with the individual electrical loads; sequentially applying power to individual subgroups during non-overlapping time periods; sequentially measuring at least a corresponding current drawn by the individual subgroups while power is applied to the subgroups; and sequentially comparing the measured current to a threshold value, and when the measured current exceeds the threshold value, repeating the increasing the number of subgroups, the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing at least the measured current to a threshold value; and when the measured current does not exceed the threshold value, repeating the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing the measured current to a threshold value. coupling an existing group of electrical loads to a common power source through a load management system; measuring an aggregate group current drawn by at least the existing group of electrical loads and comparing the measured aggregate group current to an aggregate group current threshold value; when the measured aggregate group current exceeds the aggregate group current threshold value: increasing a number of subgroups of the existing group, using subgroups that are formed without requiring information about individual current associated with the individual electrical loads; sequentially applying power to individual subgroups during non-overlapping time periods; sequentially measuring at least a corresponding current drawn by the individual subgroups while power is applied to the subgroups; and sequentially comparing the measured current to a threshold value, and when the measured current exceeds the threshold value, repeating the increasing the number of subgroups, the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing at least the measured current to a threshold value; and when the measured current does not exceed the threshold value, repeating the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing the measured current to a threshold value. increasing a number of subgroups of the existing group, using subgroups that are formed without requiring information about individual current associated with the individual electrical loads; sequentially applying power to individual subgroups during non-overlapping time periods; sequentially measuring at least a corresponding current drawn by the individual subgroups while power is applied to the subgroups; and sequentially comparing the measured current to a threshold value, and when the measured current exceeds the threshold value, repeating the increasing the number of subgroups, the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing at least the measured current to a threshold value; and when the measured current does not exceed the threshold value, repeating the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing the measured current to a threshold value. when the measured current exceeds the threshold value, repeating the increasing the number of subgroups, the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing at least the measured current to a threshold value; and when the measured current does not exceed the threshold value, repeating the sequentially applying power, the sequentially measuring at least the corresponding current, and the sequentially comparing the measured current to a threshold value.
