My understanding is that NEC 110.26 working distances apply to HVAC condenser units which are electrical equipment. If it's in front of an exterior wall that has electrical equipment like a disconnect, then I think condition 3 applies, so minimum distance for 240V equipment facing a disconnect on a wall is 4 feet. Does that sound right?

It's not very convenient for my purposes, because then I have to figure out how to run the refrigerant lines back to the wall too. But I don't want to put the condenser on the house wall, and I'd rather just do it right so I don't have to worry about spending money on a code violation later. Can someone clarify if I've interpreted the depth of working space correctly?

I know there are lots of HVAC installs where no one pulls a permit or gets inspected and they don't follow NEC. I'm not talking about those situations. I just want to figure out what NEC requires for my house.
