110.3(A) Examination.
In judging equipment, considerations such as the following shall be evaluated:
Examples of “special conditions of use” include elevated or reduced ambient temperatures, special environmental limitations, stringent power quality requirements, and specific types of overcurrent protective devices (OCPDs). The additional information needed for such special cases might be marked on the equipment, included as part of the listing information in a listing directory, or included in the information furnished with the equipment.
110.3(A) Examination.
In judging equipment, considerations such as the following shall be evaluated:
- (1) Suitability for installation and use in conformity with this Code
Informational Note No. 1:
Equipment may be new, reconditioned, refurbished, or remanufactured.
Informational Note No. 2:
Suitability of equipment use may be identified by a description marked on or provided with a product to identify the suitability of the product for a specific purpose, environment, or application. Special conditions of use or other limitations and other pertinent information may be marked on the equipment, included in the product instructions, or included in the appropriate listing and labeling information. Suitability of equipment may be evidenced by listing or labeling. - (2) Mechanical strength and durability, including, for parts designed to enclose and protect other equipment, the adequacy of the protection thus provided
- (3) Wire-bending and connection space
- (4) Electrical insulation
- (5) Heating effects under normal conditions of use and also under abnormal conditions likely to arise in service
- (6) Arcing effects
- (7) Classification by type, size, voltage, current capacity, and specific use
- (8) Cybersecurity for network-connected life safety equipment to address its ability to withstand unauthorized updates and malicious attacks while continuing to perform its intended safety functionality
Informational Note No. 3:
See the ANSI/ISA 62443 series of standards for industrial automation and control systems, the UL 2900 series of standards for software cybersecurity for network-connectable products, and UL 5500, Standard for Remote Software Updates, which are standards that provide frameworks to mitigate current and future security cybersecurity vulnerabilities and address software integrity in systems of electrical equipment. - (9) Other factors that contribute to the practical safeguarding of persons using or likely to come in contact with the equipment
Examples of “special conditions of use” include elevated or reduced ambient temperatures, special environmental limitations, stringent power quality requirements, and specific types of overcurrent protective devices (OCPDs). The additional information needed for such special cases might be marked on the equipment, included as part of the listing information in a listing directory, or included in the information furnished with the equipment.
