Yes, all of that seems correct to me. And you're right, It doesn't hurt to try the diode route, but I'd rather be safe than sorry. I'd hate to get close to the accuracy I need with diodes, and then it fall out of tolerance 6 months from now. I'm going to stick with the 60 ohm resistor for now for the 30A input, and will increase that for lower current ranges It is a 1/4W right now, which I could bump up, and will do based on your suggestion. My real problem is after that portion (CT / burden) is done, which I think it is, barring the upping of the wattage. I can rectify and filter, but am not enough of an analog expert to shift that signal down so that it's in the range of my microcontroller without using a negative supply. Right now, with 110mV / A and a 2.5V starting point, I run outside of not only a 3.3V mcu analog input, but a 5V one too. I haven't decided on the mcu, but this is a problem
