The eGauge can be set to record individual CT amperages as separate registers. Unlike power registers, amperage registers are absolute values (they do not change polarity to reflect the directional flow of current).
To add amperage registers:
Navigate to Settings -> Installation
Under Registers, click the "Add Registers" button
Name the register as appropriate
Using the dropdown menu, change the register type from "P" to "I"
A second dropdown menu will appear. Select the appropriate CT number
Click "Save" at the bottom of the page when finished (valid credentials required)
