The use of a disconnect as a raceway.

[sparkky302]

What I have is a disconnect outside of a building that feeds a condensor unit. The disconnect is fed with a 3/4" conduit. Can I pull a branch circuit in with the feeders (fed from same source) and pipe to a weatherproof GFCI below the disconnect?

Take a look at 312.8 and be sure to read the entire section.

I agree with the others but also want to point out that once you apply the required derating the feeder conductors will likely be to small.
