I've heard this before as well, but as you found, I too have never found
specific info on clearance distance. Obviously there needs to be enough
space to get your hand in there to operate the disconnect, but as others
pointed out, it looks fine. Please share if you get an actual inches
clearance. We will all then file it with the rest of the arcane, but
occasionally important info rattling about in our solar electric brains.
