Please ignore, i figured it out.

=========

I have purchased (20x) 100A SCT-013-000 Non-invasive Sensor Split Core AC Current Transformer purchased from Amazon here for a project I'm working on.

The description states "Two form of output current, voltage (voltage output built-in the sampling resistor)"

But a buyer comment states "This model does not have a resistor and as such you can decide yourself what range of current you want to have in a voltage range you can handle."

This left me confused as to whether this will work with your PCB, or if I need to remove the resistors. I purchased 20 of your PCB's this week, I wouldn't have even considered this project without them.

I don't know if this helps but I connected one of the clamps around the load of an extension cord and recorded the following voltages based on various loads that I plugged in (tip of 3.5mm plug positive, base ground).

13W load   = 0.030v
120W load  = 0.044v
186W load  = 0.059v
2020W load = 0.430v
