EMT and grounding

Seems like I've read somewhere on this board that when running wire in metallic conduit, the conduit itself can take the place of the ground wire. Provided of course that the conduit is continuous back to the panel and provides a complete path back to the ground rod, metal boxes are used, and all devices are grounded to the boxes,etc.

But . . . . I've searched and can't find the post.

Is this correct?
Is it true regardless of the number of different ciruits in the conduit?
What about 220 circuits?

Thanks,

True, but a peice of green #12 is cheap, and when the conduit falls apart because somebody kicked it, you still have a valid ground path. My 2 cents

It really isnt intended to be a complete path to the ground rod as it is a path to the neutral at service entrance.

I'll say it even more strongly. It isn't at all intended to be a path to the ground rod. It is only a path to the power company neutral.

Ya, thru the same cable or raceway as the current carrying conductors.
