Small solid core CT for small cables

Is there a way to use solid core CT’s even smaller than ECOL09 while maintaining measurement accuracy and easy of obtain?
In fact, I have a small electrical enclosure and some cables are small section (14 AWG)

Id recommend HWCT004 or DL CT08CL2 (I believe they are different brands of the same source). You can find them on Ebay or Ali. They will require cords and jacks. The accuracy is good.

Thanks, I’ll try to get and adapt them with jack
