Running 2 Circuits in Same Conduit - 1/2" LNFC - Is This Permitted?
I was going to add 1 20A receptacle at my outdoor subpanel, but I decided that I'd like to add 2 if possible. I was planning to house them in a 2-gang weatherproof box. Can I run two separate circuits in the same conduit, or does each one need to be in its own? I am using 12AWG THHN/THWN with 1/2" LNFC. I was thinking about using 3/4", but it appears that 1/2" is acceptable. Thanks for any input.

You can share the same 1/2" conduit. The two circuits can share the same green or bare ground, but should have separate black hots and white neutrals. You can use either solid or stranded THHN.

You are also supposed to group the wires together or mark them in the box and panel so that they you know which neutral goes with which circuit.
Note you could also just go with a single neutral and do a MWBC off of a double pole breaker.
