Is there a code prohibiting this installation? CT can on outside of building, 4 2" conduits with 3/0 leaving the back of can through wall into a trough, out of the top of trough into 4 200amp panels. Can branch circ. come out of the panels, back into the trough and into conduit on the bottom of the trough to supply lighting out side the building. Can the service cable and branch circ. be mixed in the same trough?
 
art. 230.7

230.7 Other Conductors in Raceway or Cable.
Conductors other than service conductors shall not be installed in the same service raceway or service cable.
Exception No. 1: Grounding conductors and bonding jumpers.
Exception No. 2: Load management control conductors having overcurrent protection.

If your CT cabinets are anything like the ones in our area, you most likely have a substantial violation here.

The labels on the CT cabinets specify not altering the cabinets, this includes adding KOs to suit your needs.


Here are a couple of pictures showing what I mean. Notice there are no KOs in the back of the enclosure. One of the reasons for this is Art 312 - bending radius of the conductors.

I am curious, do you have the same type of CTs?

That's a good question!! I was reading this and never though about that.
