Help with abnormal power readings (3 or 4x higher than expected)!

one more question. I was rereading Learning section about measuring individual circuits in US. I found that I was for years measuring voltage for some of the circuits wrong.
I have instances like:


in A I was measuring voltage only at 120v and just doubling by realPower*2
and in B I was also measuring voltage at only 120v and summing both realPower’s.

In both instances I had to be using 240v instead of 120v(if I understood it correctly). To get correct voltage reading, do I just modify x in the line below till voltage reads 240v? or is there a better place to double the voltage?
emon5.voltage(0, x, 1.7);

Also for the whole house total power, was the same scenario as in B. Where voltage was only 120v :frowning: if I understand it correctly it had to be at 240v if I am summing both realPowers coming from individual CT’s measuring each phase?
