What designation does a multi-purpose communications wire or cable for general use typically have, except in plenums and risers?

The designation for multi-purpose communications wire or cable intended for general use, except in plenums and risers, is CMG. This designation indicates that the cable is suitable for use in areas that are not plenum (where air circulation for heating and air conditioning occurs) or riser spaces (vertical spaces between floors). CMG-rated cables are designed to meet specific fire and safety standards, making them appropriate for general commercial use where such safety considerations apply. This allows for a degree of flexibility in deployment while ensuring compliance with safety requirements, especially in commercial and industrial environments.

In contrast, other designations such as CM, CMP, and CMR refer to different environments and safety conditions where the wires can be utilized, each having specific regulatory standards concerning their installation and safety.
