Now one more interesting Question:
Since it says OVER 1200AMP what if the OCP is 1200 Amp not over.
Then I take it Not Applicable . Right!
Since it says OVER 1200 amp & over 6ft wide .
Last one tonight I promise .
And Again Thanks for the time & input you guys have offered.

I think we would all agree that "over 600 volts" is more dangerous than less than 600 volts and they specifically say a ladder is OK as access.

110.33 over 600 volts is Very similar to under 600volts .
the 6 ft is there but there;s no limit on amperage!
I'd say its stricter!(referred to installations per 110.31)
(see 110.33(A).
Part (B) Acess does not mean same areas.Different spaces. Note

I guess I still do not see the language prohibiting a ladder as access in 110.26.
Proposals are open for the 2017.

So your opinion is that Fixed Ladders can be used per 110.26 600 volts & under for electrical Rooms ,If one or two doors are required.
Same for over 110.33 600 volts. Do i read you right???
If you find any additional info either way feel free to message me.
Thank you

I don't see the language in the code preventing it but I might be wrong. I just don't see it. I agree it is a horrible design choice and I would make every effort to discourage it.
I just don't know what to do if they say "show me".

I will hold the line on the accessability.

Did we ever determine how far away the ladder was?
To wit, is there enough room to get safely away from a flaming switchboard before you get to the ladder?
If you went through a door we wouldn't even be having this discussion I suppose.

Greg:
As I mentioned earlier, a layout of the room would help. Yoop included some comments as the thread grew, but nothing exact.
As to the 'fixed industrial ladder', based on what has transpired in this thread, IMHO that would create an egress path that is not accessible. Again this is my opinion.
The intent of an injured person having an egress path that is accessible and unobstructed is paramount.

I think you are reading something into the code that is not in the actual text.
Perhaps we should put together a proposal to tighten up this article and see what NFPA says.
