Well first, thanks for that - I’d never noticed the two small clear ‘windows’ on either side of my smart meter before.
But secondly, on one side the window stops where the electronic board is, so I can’t see back to where the wires are, and on the other side, while the electronic board has a notch so that I can see a bit behind it, I can’t make anything out clearly enough to identify the L1/L2 wires, let alone a CT sensor.
My smart meter is a ‘Focus AXR-SD’ made by ‘Landis + Gyr’.
Does that help identify it in a manner that I might find a schematic or a teardown?
The fact you’ve actually installed many meters gives me a great deal more respect for your opinion on this subject that what I’ve read on the internet. Can I ask what part of the country you performed those installs?
And also, is it the electrician that installs the mains wires from house hookup to meter including the CT sensor and the utility just installs the electronics board and the meter housing?
