Overview
If you're using eGauge branded CTid enabled CTs, scanning them with the CTid function will detect the correct setting for the installed hardware. When using non-CTid enabled CTs however, the CTs need to be set manually to the correct setting. Use the information in this article to determine the correct setting for your installed CTs.
Prerequisites
- Firmware v.3.02 or later.
Instructions
The model number and current rating of a CT will be found on a sticker on the CT or on a tag on the CT lead in the case of rope CTs. Use the information on the CT label and the information in the charts below to determine which setting to use.
- Example: a 100A 0.94" J&D split-core CT (eGauge SKU JD-SCT-024-0100) should be configured as:
JD JS 24mm/0.94" 100A
The CT drop-down menu format on firmware v3.02 and later is as follows:
