How Many Wires?

Using a fish tape and wire lube, and having access tees and els not more than 20 feet apart, can one pull four #10 wires through 1/2-inch conduit?

If not, how about three #10 and three #12 wires in the same conduit? They would of course be on different circuit breakers.

Four #10 wires puts you at 28% fill in EMT, which should be fine.

Three #10 and three #12 puts you at 34% fill, which should still be ok.

Remember that the sum of all bends between pull points (conduit bodies & j-boxes) cannot exceed 360 degrees by code, and the higher your fill ratio, the better off you are to limit that to the lowest number possible.
