I will be ordering Ecol09 solid core CTs, but I am unsure about the exact specs; this is for 20A circuits, 220V / 50Hz.
I found this spec sheet: http://www.echun-elc.com/UploadFiles/20171118171733625.pdf
… which seems to imply that I have a choice for outputs. Should I go for a
ECOL09-20 with a 50mA output if that actually exists?
If not, would you recommend ECOL09-20/20mA or ECOL09-50/50mA as far as precision is concerned?
