Issue
User needs to add another CT to an Energy Meter.

Product Line
Energy Meter

Environment
Sub-metering

Cause
User may have ordered the wrong version of the Energy Meter for the system they are trying to monitor. Such as ordering a 2 CT version when a 3 CT version is needed.

Resolution
Energy Meters must be ordered based on the number of CTs and voltage connections required to monitor the electrical circuit. The Energy Meter can be ordered with 1, 2, or 3 CTs (Phase A, B, and C). All Energy Meters will have 3 voltage and current terminals no matter what model. Additional CTs cannot be added to the open CT connections. Each meter is calibrated and configured to monitor the specific system that it was designed for.
