Electrical Engineers would determine the settings for the electrical protection of a generator. Mechanical Engineers would determine the settings for mechanical protection of a motor. To operate the equipment beyond thresholds would result in reduced lifespan or immediate and permanent damage to the equipment. If this is what the customer requires they have to specify that to the Engineer so that when the equipment blows up the Engineer is not liable.Diesel generators for hospitals and water pumps for fire suppression systems are generally set up with very loose settings as it is clearly worse for a patient to die or a building to burn down than to destroy a machine, and this requirement is in the specifications.

Those systems also require regular testing by qualified personnel. NFPA 25 requires monthly testing of fire pumps and annual flow testing. For low rise buildings with inadequate municipal water pressure, a water tower might be cheaper and easier. NFPA 99 - Standard for health care facilities, requires emergency generators to be tested 12 times per year.
