What is the maximum input a holder of a G.2 certificate may install and service for gas-fired equipment?

200k BTU
300k BTU
400k BTU
500k BTU

The correct answer is: 400k BTU

The maximum input a holder of a G2 certificate can install and service for gas-fired equipment is indeed 400,000 BTU. This level is established to ensure that those certified have the necessary skills and knowledge to safely manage gas systems of that capacity. A G2 certificate signifies that the holder has undergone specific training and assessments that prepare them for working with a range of gas appliances that fall under this limitation. Typically, regulations and safety standards dictate that the more complex or higher-capacity installations require more advanced certifications to ensure public safety and proper operational functionality. In contrast, the lower capacities such as 200,000 BTU or 300,000 BTU relate to different classifications of gas technician certifications, which may allow for wider scopes of work but under lower risk parameters. The option of 500,000 BTU exceeds the competency level that a G2 certificate holder is trained for, which would typically be covered under higher certification levels like G1. The established 400,000 BTU threshold strikes an essential balance between demand for services and safety measures in gas installation and maintenance work.
