First- this is a great resource. I have learned a lot from reading this today. Thanks to all of the experts who answer questions.
I am installing three new dedicated circuits in my kitchen, one each for range, vent hood and microwave. The range requires a 30 amp 240 V circuit. I'll install 6/3 NM cable for this, with a 30 amp breaker (being sure to cut the ground strap between the unit and the terminal block on the range). The vent hood and microwave each require 15 amp 120 V circuits. I'll use 12/2 NM cable for these. I plan to run all three cables (one 6/3 NM and two 12/2 NM) along the ceiling of the garage inside conduit, back to the circuit breaker panel.
My questions are: Considering derating, can I run all three cables inside the same 3/4" EMT conduit? Max ambient temp is 110 C. Could I instead use PVC conduit? Is THHN/THWN used inside conduit, instead of NM, just because it is easier to pull?
Thanks,
Daniel
