Third party CTs?

[scscscsc]

Just bought 5 Vue 2 units w/16 CTs each for a big install… but, haven’t used Vue before.

I’ve seen @djwakelee mention using two 200A CTs in parallel through a 3.5mm Y adapter to get to 400A, but given that all 3 of the 3.5mm sensor ports and all 16 of the 2.5mm sensor ports expect a 0.333VDC CT, can I use a third-party CT (like the YHDC CTs) that also produce 0.333V and have a 3.5mm plug (or things like the Veris H6811-400A-.3V or Schneider LVCT00403S, where I can easily solder on a 3.5mm plug)?

This would assume that the software has somewhere for me to indicate what amperage the 0-0.333VDC CT output represents…

I ask for two reasons:

1. This would be a much more accurate way to read a 400A main versus parallel CTs
2. I have several breakers than exceed the 50A CTs Emporia includes (pull sub-panel, EV charger, etc)

Perhaps I would just use a multiplier? For example, if I plug a 100A CT into one of the 50A CT ports, I would use a “2.0” multiplier, or if I plugged a 20A CT into one of the 50A CT ports (higher accuracy for smaller loads), I would use a “0.4” multiplier.
