Joe, Tray cable comes in all sizes from #18 or smaller to 500kcmil and larger. It can have 2 to more than 50 conductors. It comes with or without grounding conductors. Some is color coded and other is numbered on all black conductors. Most of it that I have seen has a black outer jacket and a very close resemblance to NM. Don
