Conduit capacity
Planning a future project... residential property ... North Carolina, USA.
How many 12/2 w/ground wires may share the same 2-inch PVC conduit?
Is it permissible to have one 12/2 w/ground and one 12/3 w/ground share the same 3/4-inch EMT conduit?

Best practice is to use individual conductors not cable in conduit. What is the job for which you are putting cables in conduit? How long is the conduit? Is it continuous or just a sleeve?

Cable fill is based on the major diameter of the cable
Derating issues will arise with multiple cables in a conduit.

Depends on how long the conduit is, where it is located and what those circuits are powering.
