Temperature rating for thhn wire
WebTHHN wire can be used for higher temperature ratings in wet and dry locations. The THHN wire can be used in dry locations up to 90° C, but in oil or coolant, it should not exceed … WebRule of thumb is NM is restricted to the 60°c column and the 90°c column is almost exclusively used for derating. In your scenario you can not use the 90°c column since the breaker is not rated for it. #8 THHN is 50a on the 75°c column and #6 NM is 55a at 60°c. Your breaker size has to be 50a or less. jakewilhelm77 • 1 hr. ago.
