Carlon orange flexibla raceways?
 
Does anyone know if there are special restrictions for this product? I plan on running it in my unfinished basement to my garage to hookup a subpanel for my welder.

Thanks

special like in...?

as with all materials, there are allowed installations and disallowed installations.

nap, i just had concern that since it isnt anywhere near as thick as grey pvc that there would be obvious different rules for how it is used.

nap 10-07-2010 07:17 PM

yes, there is.

not sure exactly how you are using it but the two things that come to mind as possible concerns:

not approved for direct earth burial, not acceptable where subject to physical damage.

If you have access to an NEC, it is article 362. If you go to the electrical forums main section, I believe scuba dave has provided a link to access the NEC.

nap, i will be running 4 awg copper stranded from my main panel to my garage. The sub panel will be fed through a 2 pole 80 amp breaker. If i ran grey pvc there would be a lot of turns to get around my I beam and chimney on its way to the garage. Due to all the turns i am interested in running the flexible raceway. Does this sound okay? The wires in the raceway will be 3-4awg and one 6awg for ground.

there is a funny part of that section. 362.10 uses permitted, 362.10(1) In any building not exceeding 3 floors above grade, as follows:

a. for exposed work, where not prohibited by 362.12
b. Concealed within walls, floors, ceilings


then, when you go to 362.12 Uses not permitted, it states
(7) in exposed locations, except as permitted by 362.10(1) (and others)

so, when does the merry go 'round stop? 362.12 says it is not permitted to be run exposed except as permitted in 362.10 and 362.10 says it is allowed unless prohibited by 362.12.

You do need to understand that ENT is restricted to the same amount of bend between two junction boxes or pull points as PVC is. That is 360.

#8 would be acceptable for EGC.

I believe that the orange Carlon ENT is only for low voltage use. The blue can be used as a line voltage conduit, but is limited to interior usage only.

not all ENT is blue but after reviewing Carlon's website, it does appear the orange is not rated for anything other than low voltage applications.

I figured the OP knew what he has and it was ENT while in fact, it sounds like he has innerduct.

so shawn, be sure you have ENT (that is the specific name it must be labeled with). If you don't, do not use it for regular wiring.

I forget about the grey ENT, most of the time I only see the blue.

Thanks everyone. Blue flexible ENT it is then.
