Why does the main fuse blow and not a branch fuse?

A. Here are some reasons a main fuse (say 100A) blows instead of a branch fuse (rated at 15A, for instance): 1. The two fuses’ time current characteristics curves aren’t coordinated. This could be the case with dual-element, time delay, 15A fuse and renewable fusible element-type 100A fuse.
