Hello, I live in Las Vegas and most of the commercial wiring has to be in a metalic raceway (Type I or II A Construction). If you are working with a 70v sound system for ceiling speakers and code requires you to put them in conduit (due to the location), doe the conduit have to bonded? NEC requires circuits of 50v or more to be bonded. But most 70v amps have class 2 wiring which in most cases doesn't require bonding. Isn't this circuit technically over 50v. It get confusing with normal amplifiers that are class 2 as well. Most cities would not require conduit, but Las Vegas does in many places. I would be very thankful if someone could help me with these bonding questions.
