Who is responsible for defining the temperature rating for motors used with the fueling pumps in the Type III system?

The temperature rating for motors used with fueling pumps in the Type III system is defined by the National Fire Protection Agency (NFPA), specifically in their standards relating to fire safety and electrical installations. NFPA 70, also known as the National Electrical Code (NEC), outlines the requirements for the safe installation of electrical wiring and equipment, including specific temperature ratings that ensure motors can operate safely under various environmental conditions without posing a fire hazard.

Understanding the role of NFPA 70 is crucial, as it sets industry standards that must be adhered to for regulatory compliance and safety. This ensures that motors are suitable for the potentially hazardous environments where fueling operations occur, thus preventing the risk of electrical fires or failures.

In contrast, the other organizations listed either focus on broader engineering principles, specific sectors of the petroleum industry, or general safety guidelines but do not specifically dictate the temperature ratings for motors in this context. Therefore, the correct association with temperature ratings specifically for the Type III system motors lies with the National Fire Protection Agency.
