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. [Linked Image]

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

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. [Linked Image]

That does not look like a 3R enclousure

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.
