Thanks guys, that link was exactly what I needed. OSHA regs are kinda like the code book, its hard to find your way around without practice.

I am glad to see that you guys feel the same way I do. We have had no trouble with nusiance tripping of main breakers in the year I have been there which is why I wonder where this whole thing came from.

We did have a subpanel breaker trip in the kitchen and it was because someone sprayed water at a light switch. Not a nusiance in my book. This was a series rated system.

What is ACA standards?

Thanks again for your help.
