Most HVAC units don’t have a neutral (Delta) and have 240 volt line to line. Due to the increased need for such a meter, we have added it as a product line. You may have 2 or 3 hot legs, just let us know so we provide you with the right amount of current transformers. This meter uses Blondel’s Theorem, Blondel’s theorem – Wikipedia, the free encyclopedia

There for one hot leg will be used as a reference while we give you the current transformers for the others, 1 or 2 depending on your configuration. The below spec sheet is for two CT for a 3 wire set up, but if you only have 2 wire, we merely give you only one CT.
