Code Question re PVC Schedule 40 capacity...
How many 20 amp circuits (12 ga THHN and grounds) can I legally install in 2" Schedule 40 PVC?
Also circuit capacity for 1 1/2" PVC?

Why? Sounds like you need a single circuit feeding a subpanel. Tall us what your goal is and we can better help you.

Just a note that derating will apply with multiple circuits through one conduit.

How long is the 2" PVC pipe? If it is less than 24" it would be a nipple and derating would not apply.
