When installing a wireless network transceiver (think wireless router with antenna) on a rooftop of a commercial building, the radio transceiver is connected to a small power supply unit that provides 48 vdc over the CAT5 Ethernet cable (PoE). The power supply is housed in a 3R NEMA enclosure out on the roof. The questions are?.

1. Does the CAT5 cabling need to be in conduit when placed along the parapet wall?

2. Is the rule (New York City) any different for school or hospital structures.

Again?.This is all outdoor CAT5 cabling running wireless communications equipment.

Thanks!

Is the wire rated for wet locations? Even if it's in pipe it should be..

Because that is the space where it needs to be mounted in the lease agreement. And the power supply is remote from the device?.Its 230' away on the roof.

But that does not answer the conduit question...

Not according to our NEC but you have to remember that NYC has their own codes. Unless there is somebody here that works in NYC and is familiar with what you are doing then the best thing to do is to approach the electrical inspector with your question. Hopefully also you are allowed to do that kind of work otherwise you may be opening up a can of worms.
