60 amp subpanel

[Energy-Miser]

Greetings,
What temperature column are we allowed to use in sizing the conductors for a 60 amp subpanel (for a pool powering application in this case)? Thanks in advance for your responses. e/m

Most all equipment is rated at 75 C. So you would use the 75 C column. Make sure conductors are rated at least at 75 C. 334.80 allows NM-B rated at a max of 60C but should not be using NM for a pool sub-panel because a insulated EGC is required.
