Which license allows supervision of mechanical equipment installation without BTU limits?

The Master Class A license is designed specifically for individuals who are responsible for supervising the installation and alteration of mechanical systems without any restrictions based on BTU (British Thermal Unit) output. This means that holders of this license have the qualifications to manage large-scale mechanical projects and installations without being limited by the size or capacity of the systems involved.

In contrast, the other licenses, such as the Master Class B license, Journeyman license, and Apprentice license typically come with certain restrictions. For instance, the Master Class B license may allow for supervision of mechanical equipment installation, but often includes BTU limitations based on the scope of the work it encompasses. Similarly, a Journeyman license usually allows for a skilled individual to work independently but does not include the authority to supervise projects without limits. The Apprentice license, on the other hand, is intended for individuals who are still in training and do not have the authority to supervise work or installations. Thus, the Master Class A license is distinctive in its ability to grant unrestricted supervision over mechanical equipment installations.
