Wiring question - Two hots in one conduit OK?
I need to install an outdoor ceiling fan and truing to figure out a way to connect it to next existing wiring.
I have an outdoor light with a switch inside the house. There is a hot and neutral going to that light fixture. I was wondering if I could pull in a second hot (always on) through that conduit and then extend conduit from the existing light fixture?
I am planning to have the fan always powered and use a remote control.

Yes....you can pull a second hot wire thru the conduit.
If that new hot wire is on a different circuit than the original wire.....then it will need its own neutral also.

Thanks. What is the best method to pull the second hot? attaching two wires to the existing hot and pull through two new ones?

Pulling Wire
As suggested elsewhere, pull a fish tape by attaching to the old wires and pulling tape through. Then use fish tape to pull old and new wires all at one time.

The breaker should now be changed to either a 2 pole or two single poles with a handle tie. You will now have a multiwire branch circuit. The 2 hots and the neutral need a zip tie or a loop of tape to identify the MWBC.

You can't turn that into a multi wire circuit without identifying what leg the original circuit is on. It would be easier to pull a neutral with the new power wiring if you plan to go back to the panel.
If you are just adding a wire to obtain an "always hot" from the existing light switch then you can just grab the neutral at that point.....as long as it's there.
