Volt Amp Meter 500V 200A Voltmeter Voltage and Current Meter Digital Dual Display, 0.39 Inches LED 2 in 1 Multimeter, 2 Wire Voltage Amperage Tester Gauge with Current Transformer (2 Pieces)

That system only has current monitor for whole panel. Other sensor wire are voltage and looks like just gives you % that circuit is used ? Am I wrong ?So why not just put a current monitor on whole panel and observe how much current is flowing for each circuit ? I installed these 5 years ago still working great. https://a.co/d/01sWSgVj
