Current transformers scale the large values of current to small, standardized values for measuring purposes. They provide a secondary current that is accurately proportional to the current flowing in its primary circuit. The current transformer presents a negligible load to the primary circuit.
The length of the CT clamp's cables is 60 cm.

Useful device - EV Charger Monitoring
Useful device. I am using it to monitor power consumption for my EV charger to use excess solar power only.

Good piece of tech
Good piece of tech. I 3D printed some brackets for a clean install in my breaker box. Would have been a bit nicer if the clamps were smaller but you can wiggle them in there easily enough as is. Don't close your breaker box until you've tested it, I had my clamps on the wrong way so was registering as generated power instead of consumed. If that happens, reverse the clamps.
Integration in Home Assistant is a dream, as always.
