Normal behavior? Spa higher than main circuit

I’ve recently noticed that I was only using 1x 100 CT on one of the 2 wires (red and black) for the spa which has a neutral wire so I changed the setup to 2x 50 CTs. I’m now experiencing some weird data where the spa is reaching a higher value than the main CTs.

Can this be normal due to some delay between them? Or is there something wrong in my configuration?


Looks like you have the 1st spa circuit doubled. Check the inputs in setup.

Oh, I just checked and it wasn’t doubled but the CT was set to 100 amp, I changed it to 50. Would that be the problem? Thank you

Probably, the CT in settings has to match the CT on the cable to get the right reading.

Seems to work fine now! thanks :slight_smile:
