CT Clamp small for 25am

[Gyro]

Hi, 3 questions please:
1- Any recommendation for 200A ct 35mm dia for m16 / m30.  -->OK, i will consider
2- For m16v2, what happens if ct clamp orientation is flipped? I mean the arrow, does it have to point to the electrical load?  -->it's same, no problem. it's AC signal.
3- what's the best way to order 100 or 200 m30 boards?  --> you can contact with us by WhatsApp number: +86-15381188302

for CT clamp arrow, 
zmpt101b has L,N 
so i though they must have same phase or something.

thanks for the clarification
