Does 10 gauge wire need to be in conduit?
The answer is generally yes. The National Electrical Code (NEC) calls for all non-metallic wires to be used in conduits to avoid protection from physical damage; especially if stripped.

How do you pull a big wire through conduit?
1. String Method
- Tie the string: Tie a strong string to a long, inflexible rod.
- Push the rod: Push the rod through the conduit, tied end first.
- Attach the wire: Tie the electrical wires to the string.
- Pull the wire: Pull the rod and string through the conduit, pulling the wire along with them.
How many 10 AWG wires can I put in a 3/4 EMT?

Can you run two circuits in the same conduit?
Feed separate circuits through the same conduit. You can do this, just make sure your conduit is large enough to hold the wires easily. The major downside here is that, while it only requires another conduit run, it also requires you to home run three circuits to your house.
What is the maximum number of conductors allowed in any conduit?
Although the NEC allows up to 16 current-carrying THHN conductors in such a conduit, it also requires that for any number of conductors over three, you have to derate the capacity of the conductor. The derating isn’t significant until the number of conductors exceeds nine.
