I know that you are not allowed to mix, say a low voltage line in a
conduit with line voltage wires. My question is, can you mix them if
either the line voltage wires or the low voltage wires are in their own
"conduit" inside of the larger conduit? I have a 2" diameter plastic,
flexi conduit going from my house to an area out by the road. Right now
it is used to bring 120 volts to a post lamp and an outlet in its base.
Now, if I wanted to run some low voltage lines, could I put them in a
piece of Greenfield (grounded of course) and run that Greenfield with
its low voltage wires, through the same conduit?
