What type of identification is required on service equipment under Article 230?

The requirement for service equipment identification under Article 230 of the National Electrical Code emphasizes the importance of safety and clarity in electrical installations. Specifically, service equipment must be clearly marked with information regarding the voltage and any other relevant information that would be essential for ensuring proper operation and safety.

This identification serves several critical functions. First, it helps electrical workers and technicians quickly ascertain the voltage levels of the service equipment, which is crucial for safe handling and maintenance. Knowing the voltage can prevent dangerous mishaps when working on or near the service equipment. In addition, providing relevant information ensures compliance with safety standards, allowing anyone interacting with the equipment to understand its operational parameters fully.

The specification for clearly marked voltage and other related data highlights the NEC's commitment to reducing risks associated with electrical work and improving communication among those who operate and maintain electrical systems. This requirement helps prevent mistakes that could lead to electrical shock or equipment damage, ensuring that safety is prioritized in electrical installations.
