I have a question can we install a Panduit feedthru wireway for wire management inside the electrical panel on both sids to route the wires to the circuit breakers is there a code restrictions, what if any effect to the UL listing do we have to derate wires inside the wireway (NEC ?).

I've never even thought about that or have seen it, but, I have to say, that's not a bad idea.

Depending on whether or not the installation manual for the particular product forbids you from using other than factory knockouts for wire entrance. Also, unless you penetrate at the opposite end of the panel from where the service comes in, you might be uncomfortably close to the ungrounded service conductors with your raceway, depending on the depth of the panel. Unless "feed-through" doesn't actually mean a continuous length of Panduit inside the box.

Who cares?
Most wire management with a cover is plastic anyway and most panelboards you make your own KO's in it anyway.

I'm pretty sure the OP is taking about simply installing a short piece on either side of the panel between the breaker position and the outside wall of the panel tub for wire management.

Actually a better idea than a big bundle wire tied together.

Although I probably still wouldn't do it, it's still good thinking outside the box, or, inside the box in this case. :)

The contractor is installing the pnduit wireway inside the electrical distribution panel my question was are there any restrictions by NEC or does it effects the UL listing for the panel, also do we have to derate the wires bundle inside the Panduit about 24-30" long?
 
I do not see it as affecting the listing by any means. A couple of screws to attach raceway, no big deal.

Derating- not IMO. Slotted Panduit is not going to restrict air flow in any real appreciable way in those lengths.

Is this the stuff?

If it's 24" or less derating wouldn't apply, +24"-30" then 310.15(A)(2)Ex. would take care of it, having said that IMO the conductors inside of the Panduit are not bundled anyway so the rest is moot.

THAT is a much more useful long-term solution than a fistful of zip ties. I like it.

:thumbsup:

And, it beats the heck out of the (2) 1 1/2" one hole straps I've been known to install on either side of the upper panel mounting screws, bent out, as to loop the branch circuit wiring around..... :p

This may be the new craze.

Yup. And what you are reading is free of irony, and is saying what the NEC requirements are (nobody's found anything negative, yet). What you are reading is an appreciation of the idea.
