Please I want to know how to change the curves on the TCC graph to just single lines. At the moment they are in block (bands) and it's not giving me the outlook that I like.
I can't open your attachment, but if it's showing what I think it is, given your question, there is no single line representation that would mean anything. Low voltage breakers have a lot of tolerance and you have to assume that the actual trip point is anywhere in that band. If that causes you trouble you have too many things too close together. It can be rather frustrating, but that's life.
