The facility were I currently working has several obstructions (air duct, water pipe, equipment, etc.) preventing the opening of the covers on the wireway.

I NEED THE CODE THAT RELATES TO THE ACCESS AND/CLEARANCE FOR THE WIREWAY

You only have to be able to access it, it does not have to be easy.

And if you open this can of worms, guess who will be working to get these enclosures accessible. YOU!

Hmm... I have to wonder where this accessibility requirement is coming from. Splices and taps remaining accessible is electrical common sense and also required. However, exposed installation does not mean its 'innards' have to remain accessible. Only where concealed through walls is accesibility required on both sides of the wall.

AFAIK, there is no code requiring you be able to open the covers.

No different than using conduit that you can't get into.

Big difference: You can pull wire through inaccessible conduit, as long as you can access the ends.

Disclaimer: I take 'wireway' to mean the typical trough with enclosures nippled and conduits attached.

you can pull wire through wireway without taking the covers off too. its just not real easy. NEMA1 wireway you can normally get the cover off even if you can't open it up.
 
Okay, but let's say I need to pull a new homerun through a conduit, through the wireway, and through another conduit.

How do I get the fishtape to aim from conduit to conduit through the wireway?

No comments about using a SeeSnake, thank you! :grin:

Use two tapes. But your point is valid, e.g. there could
be two wireways.

Generally speaking, you don't... similar to a conduit-LB-conduit-LB-conduit run. Additionally, fish tapes perform very poorly in wireway. Perhaps cascade-able fiberglass rods, of even a piece or pieces of PVC... which is what I'd likely use, depending on what's immediately available. Yes access is desired... but only necessary at key points for add-on runs.

To sum it up, I understand your position and agree for the better part. My position in this thread topic is only to emphasize code requirements, or lack thereof. :grin:
 
Your definition of wireway sounds more like that of auxiliary gutter.

For wireway, think trough used as raceway.

IMO if it is listed as 'wireway' it remains wireway no matter what the use.

An auxiliary gutter will likely be listed as 'auxiliary gutter' or an accessory of some sort.
