Is Type USE cable required to have a flame-retardant covering?

Type USE (Underground Service Entrance) cable is specifically designed for use in underground applications connected to the utility service. One key characteristic of this cable type is that it does not require a flame-retardant covering due to its intended installation environment. Generally, Type USE cable is not subject to the same building code requirements for flame resistance as other types of cable that might be used in living areas or non-ventilated spaces.

This means that even if it is subjected to extreme conditions, the lack of a flame-retardant covering is permissible for Type USE. However, it is important to note that other cable types might have different requirements based on their application and location, which leads to the confusion. The specific applications of Type USE cable, primarily underground and not in living spaces, justify the absence of this requirement. Therefore, stating that Type USE cable does not need a flame-retardant covering is accurate.
