Is it true or false that electrical equipment must be installed according to the listing or labeling?

The statement is true. Electrical equipment must be installed according to its listing or labeling because these specifications ensure safety and proper functionality. Listings and labels provide critical information about how the equipment has been tested and what conditions it can safely operate under. Following these guidelines helps to prevent electrical hazards such as fires or equipment failures.

Furthermore, compliance with the listing ensures that the installation meets local regulatory codes and standards for safety. This practice is essential not only for residential applications but also for commercial installations, as it maintains a standardized approach to electrical safety across all types of properties. Adhering to the listing or labeling protects the installer, property owner, and end-users from potential risks associated with improper installation.
