When using MIGB for EMT do you just screw the bushing onto the end of a EMT connector? That's what I can gather by looking at parts.

Yes. They also make them that can be used without an EMT connector like into an open bottom switchboard.

If you had a conduit run from a switchboard then hitting a pull box then landing at a panelboard and MIGB's were required on this run could they possibly be used only at certain points along the run( the box and not the board etc.) or would they more than likely be used at every point the conduit terminates at an enclosure?

Why do you think that you need them at any of the above locations?

I'm just saying that the spec calls for them sometimes so in the case when the are used in a particular run are they usually used at every conduit termination point? It's primarily for my estimating database assembly I'm building.

That depends on exactly what it says in the spec. For the most part they not required very often so the spec would need to tell you exactly where they want them installed. If it said they only want them where required by code then that would be specific to the code parameters. If the voltage were less than 250 volts to ground they are almost never required.

When used for code purposes, typically only needed on one termination of a conduit. There are a few exceptions like if you have a GEC inside, or if are using the conduit as a fault path conductor on a service for another thing that needs bonding.

See spec I come across often.

More silly masturbatory specs where do these people come from? It's like ants they're just everywhere and you can't get rid of them. It doesn't say you have to connect them to a bonding jumper. I would just install them and not connect them unless code required.

That says nothing about EMT which is what the title of this thread is.
