switchboard used as a pull box

[Stalbott]

I have a situation where a switchboard on one system is being used as a pull box for a seperate system. I know there is a code issue with this but I can not find it. Can anyone direct me to the proper code section?

Thanks!!

In the 2005 NEC you could look at 408.3(A)(3) and it's exception.

It may have changed in the 2008.

Since Roger shamed me into dragging my 08 NEC into the house....


I checked the verbage Bob, and it is unchanged -

Exception: Conductors shall be permitted to travel horizontally through vertical sections of switchboards where such conductors are isolated from busbars by a barrier.
