In commercial settings, a key requirement for the installation of electrical equipment is that it must be field marked to warn of hazards. This ensures that individuals who interact with or manage the equipment are aware of potential risks associated with the installation. Proper hazard labeling is crucial for maintaining safety standards and preventing accidents, especially in environments where multiple personnel may access electrical systems.

The need for field marking enhances awareness of any specific dangers, such as high voltage or potentially dangerous components, providing clear communication about safety protocols. This practice is part of regulatory compliance and risk management in settings where electrical equipment is installed and operated, ensuring that safety is prioritized.

On the other hand, the labeling of equipment with the origin of manufacturing, while informative, does not directly pertain to operational safety, and compliance with local codes is a more general requirement that may not address all hazards. Grounding is essential for safety, but specifically marking hazards provides direct warnings that can prevent accidents and enhance safety awareness in the workplace.
