Rowdy,
I have found in my years as a inspector that there are good contractors and there are poor contractors out there regarding the code and installation of electrical products.
I inspect everyone equal and fair regarding who they are and what type of job it is. I have found however on industrial and large commercial project, the contractors do not call in for as many inspections, so I give unanounced inspections quite a bit in my jurisdiction. This sometimes catches more code violation this way when they dont expect you.
And through my years both in the field and inspecting I have learned never to rely on a engineer for proper plan specs.
Tell me how many engineers do you know that have actually worked out in the field to put together a project before becoming a engineer. A very few.
