Can you insert your dropbox as a picture?
Also this is a forum on the NEC, it may not apply in Pakistan

I don't understand where #14 and #16 enter the discussion.

my max current is 18.75 so table 310.16 for 90C i need 14AWG
But due to temperature correction factor (62C) and conduit fill factor i select 10AWG
