When I look at this picture I do not see a violation at all.
What I see is a pain in the *%# and certainly a poor situation, but unless that tree limb was there at the time of inspection I do not see it as in the AHJs authority to force any change here.
(B) Existing Installations. Existing electrical installations that do not comply with the provisions of this Code shall be permitted to be continued in use unless the authority having jurisdiction determines that the lack of conformity with this Code presents an imminent danger to occupants. Where changes are required for correction of hazards, a reasonable amount of time shall be given for compliance, depending on the degree of the hazard.
I do not see this as an "imminent danger to occupants"
If I was asked to work on this I would recommend
it be changed but I do not feel it is a violation that could be enforced.
