I've done a bit of investigation using GPT 
and it suggests that my 20A CT clamp might be incorrect for my setup — I should be using a 60A clamp to get accurate readings. It also recommended dividing the values by 3, which seems to give more reasonable results.
Is this a valid approach? Could the issue really be caused by using the wrong CT clamp?
