While code complaint when installed per the section provided by Chris, it is really bad design. Why not a short section of SCH 80 instead?
Agreed, I run SCH 80 PVC for my GEC's any chance I get.

If the 4/0 were bare would it not be legal to install it above a dropped ceiling without conduit? I am thinking commercial here.

Why SCH 80 PVC?

SCH 80 PVC is identified for protecting against physical damage, where SCH 40 is not.
Chris
so is #4 and larger. And you have 4/0 in the pipe.
Why not?

Take a look at 250.64(B). This section requires that any grounding electrode conductor that is subject to physical damage be protected. One way to protect it would be to install the GEC in a SCH 80 PVC conduit.
Chris
I was curious as to why the op wanted to put the gec in conduit.
Maybe for aesthetics?
I was thinking maybe he didn't realize he could run the cable exposed but then I figured he probably didn't want to strap it.:smile:
How often do you have to secure a 4/0 GEC?
Chris
I don't know but I certainly wouldn't just lay it on the ceiling tiles.
