ECN Forum Forums General Topics of the Trade Voice - Data - Video Discussion Communication Wiring

Best i can find: NEC 100:

Communication equipment.
That should entail the conductors/cables for that equipment.

Telecommunication cables for-Audio,video and data. Including Computer cabling.
Converters,Inverters and batteries.(With in their communication enclosures. (My add))

So, IMO, Audio,video and data. MILIVOLTS only (or what ever that stuff runs on.

No power UNLESS the individual AND the Company are licensed for that.

My MGR is always asking If I can this or that.... I reply 'Yes'... But not for you (around the office, ok. but not at a customers site).I will come in this weekend and you can pay 'MY' Co.. They are a licensed/certified ALARM co. Not Electrical.
Massachusetts laws are VERY clear on this.
