Guys,
I'm using cable tray in my project where I am adding Singe (DC) and Multi (AC) Conductor in Same Cable Tray, with a barrier between them. The code 392 talks about A) below 1000 V and B) Above 1000 V and did not mention about combing conductors of different voltage or combining single and multi conductors. I am using DC single conductor is rated at 2000 V (#10 CU PV Wire) and the AC multi conductor is rated at 600 V (#2/0 CU). My doubt is:
1) If I could combine these together with the barrier between the them and size the cable tray with just 392.22(A) assuming the single conductor to be a multi conductor with just one conductor?
2) Are single conductors and multi conductors of different voltage ratings allowed to be combined in the cable tray with a barrier between them is usually allowed?
Ps. The DC is from the strings to the Inverter and the AC is from the Inverter to the Panel Board
