I like to monitor the current drawn on my ZW transformer track power. I currently use a Chinese made digital LED panel meter, purchased for about $10 on eBay. The issue with this method is that although it provides a nice digital display, I don't have confidence in its accuracy. Moreover, the wires it provides for connection are almost thread-thin, probably #26 AWG or smaller, and running 5 to 10 amps through wires (in series of course) that small is unsettling. I would prefer a toroidal current transformer connected to a meter, so there is no direct connection to the circuit. Does anyone have a solution like that? I am not adverse to building it myself. I know I can also get thermocouple meters for this purpose, but they tend to be very bulky and not pretty on the control desk.
