110.26 Violations Please!!!!

The last time I looked, I thought that I saw conductors installed within the cabinet and/or cutout box.
I would think that without conductors, we would not have much use for the installation of cabinets and cutout boxes. ;)


Not to mention the language used that I posted says just a little about conductors. :grin:
 
Do you really need 110.26(A) clearances when you can't work on the equipment?

I see all those same things, if you install conductors in the cabinet without regard to 312.6 you will have a violation with the cabinet not with the conductors.





If I install a NEMA 1 panel exposed to the weather it is not the weather that is in violation, it is the panel.
 
I would say the difference to your last post and the wording is, we do not control the weather, we definitely control the wiring.


How many times have we heard/seen the comment that it is not the intent, but the actual wording that counts. I see conductors all over that section of Article 312.
 
First let me say I am just shooting the breeze here, I don't think there is much we could argue about that would make less difference. :smile:

Fair enough, make it an indoor wet location. Say a car wash we are in control of all aspects of that, the water does not spray without power.

I have said nothing about intent, I have pointed out what Article 312 applies to, it is right there in black ink. It tells us what the Article applies to. If it does not mean exactly what it says it is just a waste of space.

No. Conductors can never violate that section, as it applies to the equipment the condcutors are in, and not the conductors themselves. The equipment appears to be about 6" in depth (give or take), so you could legally install 500 kcmil conductors without the equipment being noncompliant.

Seeing that Pierre and Bob have an side issue going, I'll reply to your post, Ryan...

First, I agree with your first sentence... only the cabinet et al can be in violation of 312.6.

However, I have to question when did the depth of a opening-face cabinet become criteria for wire bending space? AFAIK, the requirement stipulates only the WIDTH of the gutter is of concern.

...and as for violating wire-bending gutter space, someone is going to have to show me a terminal in that cabinet first.

110.26(A)3 refers you to (E) which exception allows less than 6.5' of headroom. No violation IMO.

NEC 2008 said:
110.26(A)(1) Depth of Working Space.
110.26(A)(2) Width of Working Space
110.26(A)(3) Height of Working Space. The work space shall be clear and extend from the grade, floor, or platform to the height required by 110.26(E). 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.

110.26(A)1 you'll have to explain to me. That step is small and appears to be under the electrical equipment for the most part although I'm sure it sticks out a few inches. I see this no differently than a housekeeping pad installed under an MCC. Very commonly done, no violation IMO.

Lets just assume the equipment is at least 6'' deep.........those doors sure look like they close to me........bringing me to the conclusion that the "Steppy Thing" is directly in the 3 dimensional working space footprint (step back space (X)30" wide or the width of equipment (X) height of working space)

As far as your experience with housekeeping pads, there is no control over how far a pad can extend in front of equipment. The NEC is pretty clear as to what is and is not permitted.........the extension of a house keeping pad is not permitted.:roll:

When it comes to working space and dedicated equipment space, IMO there's NO cutting corners.

Ahem - that is a UK installation and so doesn't violate NEC anything.

And with a filename like WolvoRoyal and a set of swing doors on the right I'm going to guess this is the Wolverhapton Royal Hospital or infirmary or something very similar!
