Eccentricity is usually expressed as a percentage. A pipe would be considered to be fully (100%) eccentric if it were lying against the inside diameter of the enclosing pipe or hole. A pipe would be said to be concentric (0% eccentric) if it were perfectly centered in the outer pipe or hole.
Not an electrician here, but I thought you only have to use bonding bushings for metal raceways or cables on the SERVICE side of equipment? So why would you need them on ALL metal raceways. Again not an electrician but I get sparky once in a while lol
you are correct and also a bonding bushing on eccentric knockout when there is an ungrounded conductor above 250 volts to ground so the bushing bonds the enclosure.
Those are eccentric knock outs bro.

Google eccentric vs. concentric..find some pics. They are 2 different types
At 1:30 those are eccentric..maybe you are talking about something else

I would drill my own instead of using knockouts
A little misleading ,If that disconnect was the main service disconnect the neutral would also have to be bonded to it.
