PM8000 series I4 Metering for 1PH3W LL with N

[BrandonReed]

I'm curious if a 3rd CT can be connected to I4 on the PM8000 to directly measure the Neutral current, and therefore calculate ground leakage current in a 1PH3W LL with N configuration. I see this is an option for 3-phase, but not explicitly shown for a single-phase system. I've attached a sketch. I have an open case with support, but was wondering if anyone here has experience with this setup. Thanks!

Hello @BrandonReed ,

I have not tried this myself personally, talking with one of the developers, this configuration was his recommendation.

Thanks, @Charles_Murison. Is it your understanding that the meter is capable of reading all three CTs and performing the calculation in this configuration? I was trying to get confirmation prior to purchasing three CTs instead of two. Thanks again!

Hello @BrandonReed , that is my understanding.
