Re: [RE-wrenches] Raceway Partitions or Barrier in Gutters

Hi Mac,

We use wireway "gutters" all the time. Our supplier mostly sends us Hoffman
brand wireways and they also sell a barrier kit:

Here is an example of a barrier and a 4"x4"x24" wireway, you'd need to spec
out the dimensions you need for your project:

Not a day for me. 

I do not care if it is UL listed or not. The
Schneider PDP is UL also. Not high reliability in my opinion! Especially at
600vdc as there is not disco that will fit in the load center or PDP that I
would trust. We all have our requirements and they can easily exceed UL !

Re: [RE-wrenches] Raceway Partitions or Barrier in Gutters

2021-02-01 Thread William Miller 
Mac, Wrenches:



I hope y’all can keep a secret:  I admit I have been getting away without
partitioning due to ignorance on the part of the local inspectors.  I do
try to follow the letter of the code, but I have not seen the safety hazard
presented by not partitioning.  Does anyone know why this requirement might
make sense?



However when I am called on it, I sleeve the PV conductors in some
appropriately sized NMLT inside of the gutter. We have also run bonded EMT
inside of a gutter in the past to meet separation requirements.  The nice
thing about this plan is crossing types of conductors inside the gutter is
not the huge issue I imagine it could be.



If you desire 100% coverage you size the NMLT to slip inside of the conduit
entering the gutter for a short distance.  Alternatively, we thread a rigid
coupler on the inside of the fitting that enters your gutter and thread up
an NMLT or other appropriate conduit connector onto that coupling inside of
the gutter.



Seems one of these methods should make your inspector happy and require
minimal fabrication.



See photo below for an example:





I hope there is something here that helps you out.

Hello wrenches,



What are folks using for raceway partitions to comply with 690.31(B) when
running AC/DC and batteries conductors through a common gutter?  Is there a
product or just something made by the installer?  These multiport inverters
make it difficult not to use a gutter and have a clean installation.



Thanks!
