Re: Non Licensed Work
Down here an owner may build his entire business firm.Notwithstanding he can non wire a commercial building for himself.This probably will come under your states constitution.And a permit is still needed.
It being a church has nothing to do with edifice codes,it is a building.No exemptions apply.

Re: Non Licensed Work
if you lot are a licensed p.e. and a ex-master electrician you know the importance to have all commercial and industrial work inspected. don't get upset with the inspector, he's simply doing his job and at the same time covering his butt! i wouldn't be suprised if the contractor doing the base building piece of work called him out to see whats going on? there is an easy solution, go him to become the audio and data let and work under his license if that agreeable. churches are usually fairly able to pay for work necessary to operate if not they tin can notice contractors who volition work with them! remember, class two wiring is one of the bigest causes of building fires...

Re: Not Licensed Work
it's a combination of "no raceway " and "allowable overcurrent protection" by the nec.
alot of this equipment is manufactured overseas and does not function--then what happens? you might take a speaker cable running through a ceiling space merely then hot that information technology's glowing! a 3rd trouble is nosotros practise not respect class two wiring as we should!

Re: Non Licensed Work
...One solar day terminal week I was at church burial conduit and installing floor boxes for a sound system in our new sanctuary.
I don't think I would accept a trouble with that particular work if I were an inspector unless yous have to be licensed to do LV work where you are. Course ane and wiring for ability and light is something else once more. What exactly was his objection or was information technology because he didn't know what you were doing?
...My fourth dimension as a firefighter, I can recall half dozen Church building fires all Full loss, 4 of those fires were caused by sound systems.
That doesn't surprise me. Some of these churches have sound installations and equipment that would brand a Broadway theatre look like small change. Why? You got me just it's common practise for volunteer parisioners ordinarily with no experience to design and install them with the church forking over the greenbacks. 
...It's not the course 2 wiring that is the problem it the fact that almost loftier end ability amps require grade i wiring but no 1 makes whatever such fauna. and then the speaker wiring has to exist installed in a chapter three method. But most remember that Zilch cord wire is ok ...
Yup. That'south 1 of my pet peeves and I've written a lot virtually it hither in the by. The NEC as well every bit sound equipment manufacturers need to get on the ball and become this situation resolved.
...and when the amp gets pushed into cliipping the clip level is a DC current at 6db's over the RMS rating of the amp. so a 500 watt RMS per ch. power amp will produce 2000 watt DC current into an 8 ohm load.
Well, non quite. There should never be a DC component on the output of an amp unless there is a problem with information technology. Really good way to toast your speakers. Most commercial amps volition have protection circuitry that will limit or shut it down if astringent clipping or other problems occur. And, in that location is absolutely no reason for "home" or audiophile equipment to be apply in a commercial installation, although I did relate the story about the time I saw 1800 watts of "home stereo" amps being used to provide background music in a dentists function!
