Third-Class Power Engineer License / 3rd Stationary Power Engineers License:



A Third-Class Power Engineer ( 3rd Stationary Power Engineers License is intended for a non-supervisory role in the power plant or generating facility as a Shift Engineer.

The fees for the Third-Class Power Engineer License ( 3rd Stationary Power Engineers License ) are listed in the license application, and engineers can apply for a reciprocal license, which is based on experience and holding a license from recognized State, Municipal, Federal and Third-Party licensing entities.

Reciprocal License Note: Jurisdictions that have a Stationary Engineer's or Stationary Operating Engineer's license does not ensure a Stationary Power Engineer license will be issued. An example: A jurisdictional license-holder has a stationary engineer's license and has experience operating a high-pressure boiler plant, but has no experience operating a steam-turbine generator does not qualify, but will qualify for one of NASOE's High-Pressure Boiler Engineer's Licenses.

The qualification to sit for examination are the individual must have 24-months in a high-pressure plant or two-year technical or science college degree with 6-months experience in a high-pressure steam plant. Or, a person holding a National (NASOE) 2nd Class High-Pressure Boiler Operating Engineer license with 12-months high-pressure experience can sit or write for the exam. Also, a license holder with a 1st Class High-Pressure Boiler Engineer and a Chief Engineer of Boiler Operations license can sit for the exam with 'no' time 'in-grade.' However, every perspective examinee above must have a diploma or training certificate for steam turbine generators that includes basic electricity. Finally, a power plant operator can sit for the examination who have 6-months experience and have taken a basic electricity course or have two-year technical or science college degree with 3-months experience in a power plant.

The exam is based on what a Shift Engineer (3rd Class) should know or have knowledge to recognize and communicate power plant conditions. The examination is a 75-Question test in a 2-hour period. The components of the exam is made up of the following:
