, by Norman Becker, says that “Once the panel cover has been removed, the actual inlet service capacity can be determined.

That's great, but assuming that you want to know if the rated capacity of the panel or the size of the master disconnect was matched to the size of the inlet service wire, how can you tell?
My inlet service wires are not labelled to indicate size, and I can't measure the diameters. So how do you folks determine the inlet capacity?
