Using a Larger CT with a PZEM-004T

I am not able to find any specks (sic) on the sensor that Indicated what the Maximum current is that the sensor can handle from the ct.

I think it is highly likely that the 1 A secondary current (at the rated primary current) will be far too great for the device.

The split-core version of the CT that can be purchased with a -004T (PZCT-02) is rated at 100A:100mA.

I don’t know if the solid-core version of the CT has the same rating. I have a PZEM-004, which is a PZEM-004T with an LED display. The solid-core CT that came with it is rated at 100 Amps max, but I have no data on its secondary rating. My guess is that it’s the same, (or close) as the instrument can be purchased with either CT.
