What is the insulation temperature rating of Type THWN wire in wet locations?

Type THWN wire is designed for use in wet locations and is rated for a maximum conductor temperature of 75°C when in a wet environment. This rating is crucial because it ensures that the insulation can withstand moisture while maintaining its integrity and performance. The 75°C rating indicates that the wire is suitable for a variety of applications, including resistance to exposure to water, but it is essential to adhere to the temperature limits for safety and to prevent insulation breakdown. Understanding the temperature rating is important for electricians to ensure compliance with the National Electrical Code (NEC) and help prevent potential electrical hazards.
