I apologize but this is one of those areas here I'm slow to comprehend.
If one chooses to use the MC-LED cable, is the Code allowance 725.136(D) and if so, are you limited to 150 vtg circuits due to the wording of 725.13(D)(2) ?
Is there a cable or cord (non MC type) that can be used from a j box to a fixture that provides the same separation as the MC-LED cable ?
Not slow....just methodical..:angel:
Firstly, the intent of a product like MC-PCS (we call it MC-LED) is under NEC 725.136(I)(1) per the UL CRD that was submitted, accepted and ratified for inclusion into UL 1569 at the version 5 printing. The aspect of 725.136(D) was never a consideration for the products evolution to be honest with you. It is my belief that item (D) is more concerned with conductor co-mingling within the enclosure and not about the cable or raceway supplying it.
(D) Associated Systems Within Enclosures.
Class 2 and Class 3 circuit conductors in compartments, enclosures, device boxes, outlet boxes, or similar fittings shall be permitted to be installed with electric light, power, Class 1, non– power-limited fire alarm, and medium-power network powered broadband communications circuits where they are introduced solely to connect the equipment connected to Class 2 and Class 3 circuits, and where (1) or (2) applies:
My product will technically STOP at the gate..........(Connector rather)
In your last part of the question "Is there a cable or cord (non MC type) that can be used from a j box to a fixture that provides the same separation as the MC-LED cable ?", if you are talking about in accordance with 725.136(D) then yes and they are listed in that section. However, if you are talking about meeting 725.136(I) with something other than Type MC cable and the new PCS component aspect then yes...look at option (1)...
(1) Either (a) all of the electric light, power, Class 1, non–
power-limited fire alarm and medium-power networkpowered
broadband communications circuit conductors
or (b) all of the Class 2 and Class 3 circuit conductors
are in a raceway or in metal-sheathed, metal-clad, non–
metallic-sheathed, or Type UF cables.
Like I have said many times......this new MC-PCS is simply one way to skin the cat......725.136(I)(1) and (2) have been around long before this cable was conceived.
