MV Cable & Cable Tray.
MV Cable & Cable Tray.
(OP)
If I understand the code correctly I can put 5KV and 15KV MV Cable in the same cable tray without haveing any barriers or up sizing the 5KV's insulation. Is this correct?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Can you name the specific portion of the specific code which allows you to think that you can do this? I don't think that the cost difference between the two insulations levels is enough that I would mix the two.

I ment to say I would install a divider in the tray and seperate the 5KV from the 15 KV. I don't know of a code requirement but I like the Ideal.

There does not appear to be any such requirement for 5 & 15kV cables, however. NEC would appear to let you mix them as you see fit, with no particular additional requirements for mixing cable (beyond what is required for all cables of same medium voltage).
RE: MV Cable & Cable Tray.
I think this could be reasonably interpreted to require shielding for both your 5 & 15kV cables (although there certainly might be an argument there). 15kV cable is usually shielded, but 5kV is often unshielded, so this might pose a problem for you....
