Modern handbooks place a heavy emphasis on control gear. This includes the devices that manage the performance of electric motors and other power loads. You will typically find extensive sections on:

Switchgear refers to the collection of circuit breakers, fuses, and switches used to control, protect, and isolate electrical equipment. The primary function of switchgear is to de-energize equipment to allow work to be done and to clear faults downstream. A top-tier handbook will detail the differences between low voltage (LV), medium voltage (MV), and high voltage (HV) systems, ensuring that professionals apply the correct safety protocols for each specific environment.
