Inspection is largely a joke.
Also, I don't believe an inspector would open a disconnect, under load. Or, kill the load, and then open it. The switch appears to be in the on position. What I like is what looks like 3/8" machine screws in the lugs. They open panelboards, but generally not disconnects.
Inspection and permits vary from a political structure in place for revenue generation, all the way up to good, solid inspection practices that could, actually save lives. Hell, self inspection is common. However, the field of home inspection for leverage purposes prior to a sales contract negotiation, or an offer a buyer is submitting, some of those individuals are extremely sharp. The home in which we currently live, I hired an inspector that was so brutal it was somewhat embarrassing. However we did utilize his findings as a tool whereby we knocked down the sales price by over 50k. Nothing personal, just business, the dude was a pit-bull with a clip board.
This is quite the opposite in the majority of large construction inspection. That environment is policed by the client, and toward the end, oftentimes the local fire authorities get involved with the logistics of the incoming high voltage, the distribution switchgear, and the fire alarm, fire protection systems.
One thing is for certain; regionally, inspection quality varies widely.
I don't know why they used a fork in the pic, a piece of copper tubing would have been much better.
My 2 cents
