It does have the divider, so its legal, the insulation does look like it is rated for the highest voltage in there. Generac has both low and high voltage in their transfer switch cable assemblies (120/240 with 12 volt dc control wires) but they do not have separation of the voltages by a divider at the termination points. Since they are a manufacture, they can get away with it
 
what awg are the conductors in that red cable? they look really small like 16 or something. Any whats with the hex crimp on the coax? all coax should be compression type connectors nowdays.
 
Here they ask for seperation of the services with a divider but the circuit shown is of a 120V run all the way across the low voltage point of usage... ...

Jude the 120 volt conductors are in the cable that is suitable to be run with low voltage cables.

SIMTRA™ Cables by Isotec™ are the first power cables that can be combined with low voltage cables within a single conduit or parallel run and still comply with NEC codes and regulations (Sections 725.133, 770.133, 800.133, & 830.133).
Since it crosses the divider before the conductors are exposed I do not see an issue. There is a divide there-- hard to see but it's there.
 
Just because somebody makes it, doesn't always mean you can use it.

I just don't see how this product is magically is legal.

Just what is a UL rated product anyway.

This is what their web site says "UL and C(UL) Rated Products"
 
It appears that some think this cable is a code violation. What code section would make this installation a code violation?
 
Just because somebody makes it, doesn't always mean you can use it.

As long as the rating of the insualtion is matched, and that is a Code article, "Not the exact words", why would it matter...

Yes, we can't installed just anything, if the manufacturer was to come up with this or any application don't you think they'd know enough to get it infront of UL... :rolleyes:
 
So this is some sort of a "new invention" - the 3 gang box and divider card???? One would also assume there is no need for grounding the box - since the back is cut out????? They want you to PAY money for this????
 
Come on, it's all legal don't you know what a 3 gang extension box is ?

AKA, Marketing ...

No I didn't go to the Class act of 725...

Frankly I think where looking at the future! ...

I know 800 waves off all of 1-4 chapters, I don't think 700 does

I think the box looks fine, it's the raceway that I think is not in compliance.

Why not?

You did see the FPN suggesting looking at 725.136(A), right?
