 Power Over Ethernet
Are there Electrical Code regulations governing the techniques for using CAT5 cable to provide power to network gear?

I'm planning on installing a Wireless Access Point in a public area of a church. The Access Point uses gets it's power over the CAT5 cable and am wondering if I need to protect/secure the cable in a certain way or if it requires signoff by an electrical inspector...

Dear Stephen,

No, power over Ethernet will not require any special cable handling or any additional precaution because at 24V DC the voltage is still much lower that that of an analogue phone line.
It is considered low-voltage anyway, so there will be no issues with NEC compliance as long as you use appropriate type of cabling for your environment.
