am i right? were a full service shop,our a/c guy put this in and said it's"ready"!.now im fighting with them,what do you think.
In my opinion it is entirly up to the inspector to determine if those switches require servicing while energized.
I agree but what's your opinion Bob? The few times that I had to troubleshoot an AC unit the first thing I did, after ensuring that the CB wasn't tripped or off, was to check the disconnect for proper voltage.
(A) Working Space. Working space for equipment operating
at 600 volts, nominal, or less to ground and likely to
require examination, adjustment, servicing, or maintenance
while energized shall comply with the dimensions of
110.26(A)(1), (A)(2), and (A)(3) or as required or permitted
elsewhere in this Code.
I have to agree with you, it says "likely to require examination, adjustment...." that word "likely" in there leaves the interpretation wide open. Anyone ever removed a cover from a junction box while there were energized conductors inside and the box didn't have 110.26 working space in front of it? Maybe you were even laying down in a crawl space when you did this task? Maybe you were even laying down in a crawl space while working on HVAC equipment, and you happened to do some voltage or current testinghmy:I think that is a choice (one that I would likely make as well) but not required.
I also think people get too caught up in these type of installations when disconnect switches are routinely installed in areas that 110.26 cannot be complied with such as HVAC equipment above suspended ceilings, underground equipment spaces etc.
What is right? There are probably many possible ways to do that installation.I have no problem with that but there was room to move everything you do it right the first time so why shouldn't we do it right the first time

I have two question prior to making the call.
Do you have ready access to the branch circuit OC device?
Is this a non fused disconnect?
Both would have to be a yes answer for consideration.
If the OC device can be accessed any time(no locked doors) and a breaker lock is in place then service can be done without circuit being energized.
If this is a non fused disconnect there is no need for it to be energized to check for damage.
I do agree that personally in any case I would have found a more accessible location, but code is minimum.
Can be done at the panel or in the unit j box. Continuity can test the knife switch. There are not any set ways to trouble shoot.
How did you determine there is no door?... i think the room also requires a door not a window.
