Feeders and Branch Circuits in Wireway

[Duncan8943]

I've got a possible situation where I may need to have both main panel feeders and branch circuits in the same 6"x6" wireway. Normally, I don't practice mixing the two in the same wireway. Are there any code issues with this?

As long as you don't mix service conductors with any other feeders or circuits in the same raceway then there is no issue.

I agree with Dennis but will add that derating could apply if you have a lot of conductors.
