Doing this, I need to derate my conductor amps by .91 (temp adj) x.7 (7 conductors in same raceway, not including grounds) or .637 total. All wire is THHN.
If any objections, please state your source; eg. NEC Code.

My objection is:
What are you trying to connect? a whole house?
a motor?
main switch?
an outlet for a microwave oven?
interior or exterior wiring?
circuit braker?
