Eco System & Power Wiring

[mstrlucky74]

Trying to determine if I can run the Eco System Link wiring and power wiring in the same conduit to the driver/ballast. From the Lutron pdf it looks like there might be a cable that encompasses the 120v and LV(eco link 2 wires).

The ECO loop can be run in with the power conductors however it must be reclassified as a Class 1 circuit and not use any Class 2 wiring methods.

Reclassified?? How is that achieved? Engineer approval?

there is MC cable specifically designed for the purpose.

something of note is it is in your best interest to make ANY 0-10 volt
dimming leads a DIFFERENT COLOR from the eco bus.

tying 0-10 with an eco bus will mean a fun filled day trying to
find it, with the lutron programmer standing there @ $1,500 a day.
it'll usually be found above a hard lid, after 4 hours of swearing.

lutron, on the left coast anyway, currently has a six week lead time
to schedule a programmer. plan accordingly.

The components other than the ones supplying power have to already be rated for use with a non Class 2 power supply. If any components listing requires a Class 2 or 3 power supply only you cannot reclassify.
If that condition is met, you can take the Class 2 supply output and route it using *exclusively* Chapter 3 wiring methods end to end.
If you do that, then you can mix those Chapter 3 wires with power carrying wires as long as the control wires are functionally related to the power wires.
However, if there is a separate sheathing or wireway around just the control wires they can be part of the same cable assembly without any need for reclassification. Not everyone agrees with that though.

Typically we would pull in 600 volt, #16 conductors TFFN (gray, purple) for the Eco loop with the power conductors.

Exposed Ceiling....must use conduit.

Here's a decent explanation from Lutron:

Great link. So how the heck would you remove all the class 2 markings?

Cover with tape or obscure with black marker?
No need to obscure the Class 2 labelling on wire since you will not be using that kind of wire!

Is safe to say that almost no one does that.
