Can I use the 200A CT's on circuits other than mains?

Yes, but it may affect how your device calculates usage depending on how they're used. Details here.

Designed with precision and adaptability in mind, the Vue: Gen 3 utilizes current transformers (CTs) as sensors to measure electrical currents flowing through circuit lines. To cater to different monitoring needs, the device comes equipped with two sizes of sensors: 200A for main line monitoring and 50A for branch circuit monitoring.

Using 200A CTs (and main ports) on branch circuit usage: What You Need to Know

1. Integration and Display in the Emporia App: When sensors are connected to the mains ports (labeled A, B, and C), the Emporia app aggregates the data from these sensors to display a combined total or net usage. Currently, the app does not support the separation of data for individual mains sensors. This means all mains consumption, regardless of the sensor size used, is presented as a single cumulative figure.

2. Impact on Usage Calculations: The app calculates percentages and balance metrics based on the total (net) usage data. It's crucial to note that if 200A CTs are employed not directly in monitoring the main upstream lines but are instead used in place of 50A CTs on branch circuits, this can lead to significant discrepancies in balance and percentage calculations. The app assumes a specific configuration for these calculations, so deviating from this can affect the accuracy of these calculated metrics. Despite these potential disparities in balance and percentage figures, the accuracy of the raw measurements themselves remains unaffected.
