I bought a DROK AC display meter and it works fine when the current transformer is on L1 or L2 for measuring 240 loads and load between L line with the transformer and Neutral but nothing is measured between the other L line and Neutral (non measured line). I can pass both lines through the current transformer, one entering from the opposite direction but I get double current reading. (Obviously if both are from the same side they cancel each other. Two current transformers on both lines in series, but won’t that give half value of loads to neutral? Any ideas how of how to total load of both 240 and 120V loads with one meter? How is it done the right way? Stumped?
