Correct, as I use three sensor clips (clamps) at my house, although not on
three phase, I have three different supplies split after the meter, for
Economy 7 usage, strange wiring!

it then SUMS all the wattages together from the three inputs (sensor
clips/clamps), and if you generate you own energy, solar/turbine, a fourth
clip is used to SUBTRACT the wattage, readings POWER IN USE, GENERATED
POWER, AND NET POWER, can be displayed, and connected to computer for
historical display.
