My water softener is 10" too close to the disconnect (Square D non-fused) if I apply a strict interpretation of NEC 110.26 30" side working space and I'm wondering if I need to worry about possibly having to move the softener before the condenser is installed.. and before inspector comes out.
After reading about this more on the forums, I realized my disconnect is protected by a 30A breaker which is just a few feet away on the main panel on the same wall, and that therefore maybe NEC 110.26 doesn't apply to my disconnect? Because of the convenient upstream breaker, it is unlikely to be energized when someone is working inside the disconnect. Are local inspectors typically ok with this viewpoint?
I found the following on another discussion forum:
"A/C disconnects are not covered by article 110.26 because you can de-energize it to service it."
An article in ECMag.com says:
"Depending on interpretation, one could argue the clearances described in 110.26(A) are only required where it is “likely” that “examination, adjustment, servicing, or maintenance” are necessary while the equipment is energized. The clear working space that is required by the first sentence as described in 110.26(A) may be eliminated only where examination, adjustment, servicing and maintenance are not “likely” to occur when energized exposed live parts, etc., are present."
