Where are flat cable assemblies allowed to be installed?

Flat cable assemblies are allowed to be installed in exposed locations because they are designed to provide flexibility and ease of installation in scenarios where traditional wiring might be cumbersome. These cables are generally constructed to withstand environmental factors and can be used without the need for conduits in specific applications. When installed in exposed locations, they can be secured properly to ensure safety and accessibility for maintenance.

Other installation parameters, such as underground or in inaccessible locations, may not be permitted due to the potential for damage or difficulty in servicing. Additionally, while flat cable assemblies can sometimes be installed in conduits, it is not a requirement for their use, making exposed locations a suitable option for their installation.
