    I agree the more working space the better. That being said.
    110-26(a)¹ is referring to ....to keep it simple electrical circuit breaker panels.
    By others definition of it we would need the 3' clearance for a simple light switch.. where do you draw line?

      By definition it could mean a simple light switch

      " (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."

      Note the word equipment above and devices below

      Equipment. A general term, including fittings, devices, appliances,
      luminaires, apparatus, machinery, and the like used as a
      part of, or in connection with, an electrical installation.

        You can ask this question to ten different inspectors and you will get both answers. I know we always try and get clearance but what about in a crawl space. How do you get the height???? We always try and get the disconnect in the most accessible area.

        The odd thing is I can install an entire panel 1 foot off the ground with a wp cover that hinges at the top and it is compliant. I have actually seen it like that before. I was not happy to have to work on it.

        She inherited a million bucks and when she died it came to me
        I can't help it if I'm lucky

          As Roger pointed out that section includes equipment which could be a counter top receptacle which will never have the required clearance.

          This all goes back to the point I was making in post #10, this entire section is horribly written.

            Looking at the definition of "Device"
            Device. A unit of an electrical system, other than a conductor, that carries or controls electrical energy as its principal function.

            It absolutely includes a light switch.

              Clearance required under 110.26
              It is beyond a stretch to try to make a case for no compliance needed.

                You could also make the case that the code for clear working space doesn't mention disconnects.
                I can build anything you want if you draw a picture of it on the back of a big enough check.

                  You could also make the case that the AC equipment control and power box needs 110.26 clearance, not just the disconnect.

                    That is true and if you go by the letter of 110.26 you would have to maintain clearance around receptacles. Remember it says 'equipment', which in 100 defines as "A general term....devices....in connection with an electrical installation."

                    Now 110.26(E) "....Switchboards, switchgear, panelboards, and motor controls...."

                    Yes, I know it's a word game and yes I'm am playing the devils advocate.
