Would be great to get a picture of the zener diode soldered onto the lead,
(I am a real newbie at this) (orientation and specific zener diode specs, would be really nice)
I suspect that with solid core CT, you are more likely to plug/unplug while the circuit is hot,
although I suppose I could just trip the circuit breaker.
Although thinking about this, I want to put a clamp around the main feed into house, so I can
measure import/export (I have Solar PV) as well. And that one is hard to get at, and I supppose
it will always be “hot”
Or is it just safer to power down the IotaWatt when plugging in CTs
