Temperature rating of thhn wire
WebBasically, it depends on which type of wire you have. You should look at: 60°C ampacity for these types of wires: TW, UF. 75°C ampacity for these types of wires: RHW, THHW, THW, THWN, XHHW, USE, ZW. 90°C ampacity for these types of wires: TBS, SA, SIS, FEP, FEPB, MI, RHH, RHW-2, THHN, THHW, THW-2, THWN-2, USE-2, XHH, XHHW, XHHW-2, ZW-2. 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.
