I need to install telephone cable(50 pair,22awg)in an outdoor cable tray at my industrial facility. It will be in a tray with instrumentation cables.
Does it have to be "tray-rated" cable?. I've been told that direct-burial, gel-filled cable is permissable.
I've contacted several manufacturers and none of them make this cable with a tray rating.
Thanks,
Paul
