parallel feeds same conduit code reference

[Angel Electric]

I have a feeder that im tapping in a ct cabinet and extending . Can i run new conductors within same conduit . They are feeders for the same panel which is parallel fed.

What size are they? Assuming your conduit fill calc allows this, did you figure in derating?

I think your biggest problem will be complying with 310.4(B) especially 310.4(B)(1) if the conductors are relatively short.

FYI, they moved that article to 310.10(H)1-6 for the 2011 book.
