What type of installations is Type CL3 cable suitable for?

Type CL3 cable is designed for general-purpose installations in a wide range of settings but is specifically restricted from usage in certain air handling spaces. This designation originates from the cable's construction, which is suitable for communication and sound distribution applications, including those that might occur in schools, offices, and residential units.

The critical aspect of Type CL3 cable is that it can carry signals to distances of up to 300 feet without significant signal degradation, making it a versatile choice for various installations. However, it must not be installed in air handling spaces because of the potential for distributing fire and smoke in the event of a fire, which is why it adheres to strict regulations designed to maintain safety in structures.

The other options are limited in scope when compared to the versatility of Type CL3 cable. For instance, stating it is suitable only for residential buildings or multi-family units restricts its use to those categories alone, while Type CL3 is applicable in many settings beyond just these residential contexts.
