What is the maximum temperature rating of Type XHHW insulation when used in a wet location?
To find:
The maximum temperature rating of an insulation of Type XHHW, when used in a wet location.
Answer to Problem 1RQ
The maximum temperature rating of a XHHW type insulation is 75 degrees Celsius or 167-degree Fahrenheit, when used in wet locations.
Explanation of Solution
According to National Electrical Code (NEC), the maximum temperature rating of a type XHHW insulation is
Hence, we can say that the maximum temperature rating for a type XHHW insulation in wet conditions is
