scjohn, I'm talking about Rigid Non-Metallic Conduit as defined in art. 352- RNC. What part of the articles I referenced makes you think RNC is acceptable for "Places of Assembly"?

amp-man, They want to hire me to install the service entrance and distribution panels. I am just shoring up my position to shoot him down tomorrow when I meet with him. I want to be able to give specifics as to why they can or can't do options he is likely to propose. This guy isn't a DIYer, he's a card-carrying IBEW member. If they want to hire me to fix this mess I want to be able to tell them what their code compliant options are and how much it's going to cost them. And whether I take the job or not, the inspector is going to be briefed thoroughly on the entire situation.
