EV Wiring Electrical Question

[MYPWR]

I am asking if any electricians out there can answer my question.

Tesla Wall Connector gen 3 installation:

Question: Using #6 THHN copper wire rated for 90c (194 deg) installed in a 3/4 electrical PVC conduit which is rated for 90c max BUT what if you use a flexible non metal conduit which is rated for 70c or 80c (176 deg) does this derate the 90c installation. Thanks!

I am not an eletrician, but if you want to find if there is a specifc NEC rule providing
a precise answer your question, I would suggest that you also post your request on this forum:
