I saw a resedential panel in which the electrician had pulled all of the circuits thru a piece of 2 inch pvc conduit. Isn't this a code violation and if so where is it in the 2002 N.E.C.?

Unless there was damage to the conductors, I don't think it's a violation. Why do you?

Although there are exceptions, this practice would be a violation of the basic rule of 312.5(C). However, this tpye of installation does seem to be common in some areas of the country.

Unless there were very few cables involved, I don't see how this installation could be in compliance with the previously mentioned 312.5(C). I've measured a few brands of Romex & depending on the wire gauge, the limit could be as few as 5 cables in a 2" PVC. Also, very often the requirement for derating is overlooked in this type of installation.

Fill derating does not apply if it the conduit is installed for protection from physical damage only and is not a complete conduit system. See Chapter 9, Table 1, Note 2

According to 312.5(c) it is a code violation. The circuits were being pulled from the basement into the bottom of a flush mounted panel. There were 16 12-2 circuits, 1 10-3 circuit, and 1 6-2 circuit. All of these wires were squeezed into a 4 ft. piece of 2 inch pvc conduit. I don't see how he got them in. Had to use soap! Thanks to all for the input. P.S. The gentleman had a restricted license good for only 200 amp services. The house has a 600 amp service.

I'm curious. How big does a house have to be to need a 600 amp service? (asks me, crusing by on 125)

Ron,
312.5(C)(g) doesn't say anything about the conduit being installed as a system. The entire exception expects the conduit to not connect to anything at the top & if thats the case, why bother putting in part g of the exception?
The use of conduit for this type of installation is rarely done for protection, it is for apperance, so I don't think Note 2 to table 1 of chapter 9 applies.
Of course, I've been totally out in left field before.
Anyone else have an opinion on this?
