Thanks for all the responses. I understand the possibilities of over concern in installing IG's. This is a new building and I am overseeing the electrical installation. I am also the sound tech. For this reason I feel the need for a "clean install". The cost would be minimal to avoid the posibilities of complicaitons down the road. As for the audio, our pastor has made it clear that we will try to do it on our own. I know this is not recommended, but that is a conversation for another forum. Thanks, John. The audio would be all balanced lines. We installed 2 sets of 2" GRC in the floor for the runs.

The only circuits on the subpanel would be lighting, plugs and maybe the feed to a baptismal heater/motor. All HVAC would have its' own subpanel. Right now I am working with a local lighting design firm to come up with a layout for the sanctuary. No HID's, no florecents, no hanging fixtures. The pastor only wants recessed downlights.

Thanks for the replies.
Blessings, Mark
