To Display real-time current, an optional (Included in Deluxe kits) Current Measurement transformer part number CR8450-1K-T7QC must be installed. Unlike the GFCI transformer, only 1 hot line runs through for current measurement.

Part CR8450-1K-T7QC is available in the OpenEV Store

Troubleshooting Steps

1 - Ensure only 1 hot line is running through the coil.

2 - Verify the 2 pin connector is securely connected to the A_CT pin header

Additional Troubleshooting Steps

1 - Using a multi-meter - disconnect power and the measurement coil, measure resistance of A_CT from 1 pin to the other pin, resistance should be about 22 ohms.
