Which Grade of engineer must operate in plants with an unlimited horsepower?

The requirement that a Grade A Chief Engineer must operate in plants with unlimited horsepower stems from the responsibilities and skills associated with this level of licensure. A Chief Engineer, especially at the Grade A level, possesses the highest level of expertise and training necessary to manage and operate large and complex boiler systems that produce significant power output.

This role involves not only operating equipment but also ensuring safety protocols, compliance with regulations, and maintaining efficient operation of the entire boiler system. The ability to handle unlimited horsepower means that a Grade A Chief Engineer can make informed decisions regarding the operation and maintenance of engines that generate the highest levels of energy.

In contrast, the other grades of engineers are restricted either by horsepower or the complexity of the systems they are authorized to operate. This distinction is crucial to ensure that only those with the most comprehensive training and experience are entrusted with the responsibilities inherent to managing high-capacity systems.
