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.

are the holes in the backplate open?? or are they closed by anything?

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.

You know it might fall over with the weight of the red tag. A joke

Bill:
Guess I should choose my words a little more carefully......

Like TheComputerWizKid said...it may fall over from the weight of the tag! I meant that if I was to "slap on the red tag" I probably would knock it over.

A definite RED TAG

This is a 3R rated EXO, when installed properly, I've seen a few of them around but don't like them too much.

Here's a cut-sheet for George's "Invisidorf"!

For the "After" picture of this install, look at the photo of another disconnect installed without support in the Violations section. It is about 1 swing of a ladder being moved from this to that.

Within a year or two this disconnect will be the perfect beehive. I was on a roof this summer that is common to 10 dwelling units. The A/C units are on the roof and the disconnects are mounted the same way. I tried to open one and it was full of bees. The reason for trying to open it was the A/C unit was not working. I am allergic to bee stings, so I went home early that day [Linked Image]

I used to use "Invisidorf" but it kept getting lost on the job. [Linked Image]

You guys are being a little picky aren't you?

This switch is braced with the piece of LFMC. [Linked Image] what more do you want.

Some duct tape over the holes? [Linked Image]

I can hardly wait to see how this guy meets the requirement of a receptacle within 25 ft.
