Wireway needs to be accessible?

[Tainted]

I am working on a project where I’m using a wireway as a raceway for my feeders and it will be covered up by a wall. If a wireway is concealed in a wall and the wireway has a cover, does it have to be accessible?

If there are splices or taps then those need to be accessible. {376.56(A)}

Has to be exposed with few exceptions 378.10 & 386.12

What if it’s a metallic wireway?

So we can run it concealed as long as we provide access to conductors?

that is NOT what it says.

386.12 says you can conceal it except as permitted in 386.10…

So I wanna run a wireway from the basement through a couple of floors, and the wireway is going to be concealed, is there anyway to do it?

I don't see how since it does not say you can run it thru a floor. Only thru a wall. You could always make some kind of accessible chase that went through the floors and install it in the chase.

376.10 Uses Permitted. The use of metal wireways shall be
permitted as follows:
(1) For exposed work.
(2) In any hazardous (classified) location, as permitted by
other articles in this Code.
(3) In wet locations where wireways are listed for the
purpose.
(4) In concealed spaces as an extension that passes transversely
through walls, if the length passing through the
wall is unbroken. Access to the conductors shall be maintained
on both sides of the wall.

Looks like the code pretty well expects some form of pipe rather than a wireway for this situation.
Pulling conductors through a wireway after assembly could be a problem, and that would, I think, be required for a raceway system.

Too risky.. like you said, it doesn’t say anything about passing through floors

Depending on the structure and rules beyond the NEC, firestopping might be a bear,

I mean yea because it takes up less space …

I have seen busway run vertically between floors in some office buildings. I never looked close enough to see how it went between floors. Now that you mention fire stopping, I wonder how they did it.

I thougth that in that other thread it was pretty much agreed upon that using a wireway for that purpose wasn't feasible.
