Handbook Solution:

Turn to the chapter on Motor Starting Characteristics . The handbook reminds you that a NEMA Design B motor draws 600% of full load current during locked rotor (starting). Check the breaker’s instantaneous trip setting. If it is set to 10x (standard) but the inrush peak is 12x, the breaker will trip. The solution: Use a time-delay fuse or a breaker with a higher instantaneous setting (e.g., 13x) or a soft starter, as detailed in the Coordination tables.

The Switchgear and Control Handbook is a masterpiece of traditional electrical engineering. It teaches the "hard skills" of power systems—understanding the mechanics, the physics, and the control logic. The old workshop smelled of ozone and decades-old

Protection:

Automatically cutting off power during a short circuit or overload.

Is this for a audience?

It teaches the engineer how to quench this arc. It details the mechanisms that prevent a minor fault from becoming a catastrophic explosion. In its pages, the reader finds the intricate dance of the "control" aspect: the wiring diagrams and schematic logic that allow a human operator in a climate-controlled room to safely manipulate massive machinery miles away.

Protection:

It detects fault conditions (like short circuits) and interrupts the flow of electricity to prevent damage to the downstream equipment. Check the breaker’s instantaneous trip setting
