What is the Fahrenheit temperature rating for THW conductor insulation?

THW conductor insulation is rated for a temperature of 167 degrees Fahrenheit. This specification aligns with the standards set by the National Electrical Code (NEC), highlighting the capabilities of THW insulation, particularly in environments where higher temperatures may be encountered.

Understanding the temperature rating is crucial for applications involving electrical wiring, as it ensures that the insulation can withstand operational heat without degrading, thus maintaining safety and performance. The 167 degrees Fahrenheit rating denotes the maximum continuous operating temperature, making it suitable for various applications where moderate heat resistance is needed.

Other temperature ratings for insulation materials may differ, which can lead to confusion if one does not recognize the specific rating associated with THW. Hence, knowing that THW is specifically rated at 167 degrees Fahrenheit is important for proper application and adherence to electrical safety standards.
