ANSI Cable Proection

(OP)
I am from IEC world and currently working on ANSI project.
I have an argumment with my collegue  regarding the sizing of the cable.

PHILEC, for future reference, when making a link to another thread in Eng-Tips, you only need to copy the thread info below the thread title at the top of the page; thus thread238-179324.  Your link and this one both go to the same place, but hover your mouse over each and you will notice that this link provides a tool tip with the name of the thread and the forum.
