NESC Guidelines question

[Robert Lindsley]

Hi there,

I own a small apartment building with 5 buildings. There are wires that stretch between each building for Duke Energy, Comcast, security cameras, etc.

Last month a Rent-A-Center truck took out a bunch of my lines - I have the whole thing on video:

Their insurance company is refusing to pay the claim because they say my wires are not high enough and do not comply to NESC Guidelines.

Does anybody know what NESC is, and as an apartment building owner is there some expectation of compliance? I've never heard of any of this.

Thanks!
Robert.
