I've always understood the term "engineering supervision" to mean that the site had ongoing engineering oversight of the operation of the electrical system, such as you might find in a major industrial or institutional facility. And thus, that there is never "engineering supervision" of a residence or small business.
In other words, the word "supervision" implies an ongoing activity, as opposed to, say, "review", which would imply that an engineer did his calcs, stamped the drawing, and was done with it.
Any other thoughts on this?
