Per the NFPA, what should each overpressure protection device be adjusted to limit?

The correct limit for adjusting each overpressure protection device is to gas pressure of 2 PSI, according to the National Fire Protection Association (NFPA) standards. This specific limit is crucial for ensuring safety within gas distribution systems and for preventing overpressure situations that can lead to dangerous incidents such as gas leaks, explosions, or equipment failure.

Maintaining this pressure limit is integral for the operational integrity and safety of gas systems. By regulating pressure to this level, the risk of damaging components or exceeding safety parameters is minimized, thereby safeguarding both personnel and infrastructure.

It's important to refer to these established safety guidelines when setting up or maintaining gas pressure systems to ensure compliance with the latest standards and to uphold safety practices in the industry.
