That's pretty much what I meant, Greg. Even in a big box, that's still a bit of work. I don't like to work any more than I have to.
It appears that many 30/60A disconnects use the same housings with different guts, so a 30 amp pullout disconnect is chock full of room.
I had to wrestle with one of those toggle "motor starter" switches in a DEEP box last week in a block wall. It was still enough to break a sweat to get it put back together.
