This is per the NEC Handbook, 2005 edition. Your municipality may use different rules. I am not an electrician.
Per Table 5, chapter 9:
Approximate area of 14 ga. THWN is 0.0097 sq. in.
Approximate area of 6 ga. THWN is 0.0507 sq. in.
0.0097 * 3 = 0.0291
0.0507 * 4 = 0.2028
...total area 0.2319 sq. in.
Per table 1 chapter 9, you are allowed 40% fill for more than two wires in EMT. So, 0.2319 / 0.4 = 5.7975 sq. in. minimum conduit area, which means you'd have to use 2-1/2 inch trade size EMT, which is 5.858 sq. in.
Hope this helps.

What is conduit wiring?
Conduit wiring is synonymous to wires in a pipe.
Can you put two wires in one conduit and two wires in another conduit of the same circuit?
YES
Can you use single conductor 14 gauge wire to wire a three way switch?
The key is the protection of the wires. If you are using single wires you will need a conduit of some sort. Don't just run the single wires in the wall. Multi wire Romex or metallic shielded cable are used to provided added protection to the encased conductors.
What size conduit do you need to install a 0000 wire?
4/0 gauge wire, depending on its insulation type is rated from 230-260 amps. Assuming you are running a new power supply with the 4/0 wire, you will have a minimum or three 4/0 conductors and a ground wire for a single phase power supply and four conductors with ground for a three phase power supply. Three 4/0 wires require a minimum 2 inch conduit. Four 4/0 wires require a minimum 2 and 1/2 inch conduit. These conduit sizes I'm quoting come directly from the NEC, the National Electric Code. These sizes of conduit are determined by the basic rule that all the conductors in a conduit are not to exceed 40% of the volume of the pipe. The other 60% of air space is required for heat dissipation.
