Underground PVC

[Designer69]

I was looking up the NEC and I couldn't find anything about PVC in it. Wierd, I'm looking to find what the underground burrial required depth is for PVC not in a ductbank.

You might want to look under rigid nonmetallic conduit, which includes PVC.

Look at Table 300.5 Column 3 (2005)

and if you're looking at underground requirements, it might not hurt to look at 300-5

Doesn't the '08 list it as PVC for this reason?
