I'm wiring up a bathroom in a church, i need to know if i can run a gf circuit in my conduit with my switch as well or do i got to make them separate? i know in residential its seperate. but what are the rules for commercial? so you all know. we gatta bury the pipes, so we're using existing conduit(like 1960ish emt) and old plastered building walls.

That shouldn't matter. They just couldn't be in the same raceway coming into the box where the device's are because in that box it would need a divider.

Take a look at 300.3(C)(1) and 406.4 (G).

That's my point, and it does matter according to your second sentence.

Ok, the op is talking about just the raceway. We need a little more info.

ok we got one raceway right now and that is the orginal and it's hooked into a switch that is gonna be replaced with a motion sensor(low voltage) we need to install the gfi and well we don't wanna cut into the wall more then we need too. can we run the lighting and the gfi together? this entire building is constucted in rigid electrical wise if that gives you an idea how old it is.
