Can you run 220v and 120v in conduit?
It is perfectly ok to run different voltages in the same conduit, however you must take into account that once you reach more than 3 current carrying conductors in a conduit a deration factor will come into play (Table 310.15(B)(2)(a) NEC 2005. Also you must watch your conduit fill.
