Is the attached picture an approved installation per NEC? it is located on the roof feeding rooftop HVAC equipment.

thanks
:?

I am sure the whole installation is not listed to be turned sideways like that. :)
Seriously, I think the lack if support for at least one of the pieces of flex is a violation and I cannot see well enough to say about the flex to PVC transition.
The Square D box could use some paint.
And I would guess that the big pipe with reducer is gas. NEC may not mind the proximity, but other codes might.
Is the box a fused disconnect?
 
GoldDigger,
Good call on the angle of the installation!
It is a non-fused disconnect. The installation is bonded correctly also.
The disconnect was mounted to a wooden support structure to the roof floor and was falling apart. We asked that the disconnect be relocated to a an interior structure wall but this is what the electrician installed.
 
I do not know offhand of any code provision preventing mounting the disconnect on a suitably strong railing. From the presence of the railing, I assume that part of the roof is accessible once you are up there to work on the HVAC.
 
(3) Height of Working Space. The work space shall be
clear and extend from the grade, floor, or platform to a height
of 2.0 m (61?2 ft) or the height of the equipment, whichever is
greater. Within the height requirements of this section, other
equipment that is associated with the electrical installation and
is located above or below the electrical equipment shall be
permitted to extend not more than 150 mm (6 in.) beyond the
front of the electrical equipment.

It does not appear to me that the work space is clear as there is a pipe in the space.

What is the length of the sealtite coming from the left bottom of disc. that runs along the gas line ?

That's what jumped out at me too, but the photo cuts it off just at the critical point. If that is over 6ft, then the rules allowing it are not being followed WRT support, starting with the fact that the first support must be within 12". And can you support it by clamping it to a gas pipe? I don't know, but I wouldn't even try that one.

Around here by the way, the AHJs would count BOTH pieces as cumulative in the 6ft rule, since they are the same circuit. I don't agree with their interpretation, but it's one of those things that's never been worth fighting over.

Re: the pipe in front of it, seems to me that I've seen this discussed in here before in the past, especially as it pertained to pump houses or swimming pool sheds.
 
Today I saw a wall mounted AC unit about 25 ft up feeding a second story unit. The unit was mounted on a wall bracket and the disconnect was right beside it. Im finding it hard to say this is code but the disconnect is at the unit only problem is its not readily accessible without a ladder, but if your working on the unit you will have a ladder I assume, any thoughts on that.
 
Well, I would start by saying that it was accessible (no locked doors, no stuff stored in the way) but not readily accessible. And it certainly is in sight of the unit. I think that the code allows it to be mounted on the unit, but maybe not inside it.
Now any convenience receptacles also mounted up there would not be readily accessible, but receptacles on the ground would be more than 20 feet away.
Complicated, yes?
