Looks like load monitoring. There should be another control box right near by, unless it has been decommissioned.

Split-Core Current Transformers. Used for smart metering, load management and LEED rating.

Current measuring transformers. Where do the wires go?

CT metering, the small wires go to the Meter.

Looks like it.

Cool, thanks.
