The Air Conditioning Contractor "volunteered" to wire the new unit. The disconnect is supported by the 1" conduit connected to concentric knock-outs in the bottom.

I call these pics "floating disconnect"

Personally, I think they're using that new "invisi" dorf.

I've heard it was great, but I didn't think they had it rated for 3R use yet.

If somebody pulls that handle in a hurry, he might disconnect a little more than he bargained for!

It looks like there's a set screw EMT connector beneath it.
Maybe that would give rain a place to pour out after coming in through all the holes.

That it looks like a 600-volt switch doesn’t add to any willingness to get within 10 feet of it, either. You gotta’ wonder if some contractors bank on the fact that it’s on a roof, so a building or fire inspector won’t likely see it.

He could have saved money by not using a 3R can. With all those holes it would't make any difference anyway.

The only bad thing about using "invisi" dorf is get the "invisi" spring nuts to line up.

As one of the AHJ's who do go "up on the roof", I think that I would think twice about hanging a red sticker on this.

Yes, there are a few contractors that "gamble", but they loose!

From the pics, it appears that the disco is a 3R, check out the "lip" at the top of the front door.
