Assalamuwalaikum L9 : Thalatha al Usool Nadhr(vow): Can you please give an brief example when Nadhr becomes a major shirk ? May Allah bless you.

Nazr—that is major Shirk—is to do Nazr for other than Allah. As we have explained in The Three Fundamental Principles as well as the Book of Tawheed, Nazr is not divided into major and minor Shirk. It is only major Shirk.
