The minimum insulation rating of a low-voltage conductor in an RV is ______________________.

The minimum insulation rating for low-voltage conductors in an RV is 90°C. This rating is important for ensuring that the conductors can withstand the heat generated during normal operation without degrading. Higher insulation ratings indicate that the wire can endure elevated temperatures, which contributes to its reliability and safety.

In an RV environment, where temperatures can fluctuate significantly and where electrical systems may run continuously, using conductors that can handle higher temperatures helps prevent issues such as insulation failure, short circuits, and potential fire hazards. The 90°C rating indicates that these conductors are designed for applications where moderate heat is expected, supporting the safe and efficient operation of the electrical systems in recreational vehicles.
