Good point Bob. It is a common misconception, in the location that I live, that ALL "non power circiuts" (cable T.V., telephone, doorbells, cat5 data, intercoms, inwall stereo speakers, security systems, CCTV, ETC, ETC...) are class 1 or class 2 circiuts and are therefore not required to conform to code. If this were true, then why would article 820 have been written?
