What is the marking requirement for service equipment rated 1,000 volts or less?

Service equipment rated 1,000 volts or less must identify suitability for service equipment to ensure that it meets specific performance and safety standards required by the National Electrical Code. This marking is essential because it informs users and inspectors that the equipment has been tested and is deemed appropriate for its intended use, particularly in safeguarding against electrical faults and failures.

The markings provide details about the equipment, such as its ratings, type, and any conditions of use, enhancing safety and reliability. This requirement reflects the overall goal of the NEC to promote safe electrical installations and prevent potential hazards. By clearly identifying the suitability, it facilitates compliance with safety regulations and proper maintenance practices among electricians and facilities personnel.
