[RE-wrenches] protecting wire below 8'

[August Goers]

Hi Kirk - We work in San Francisco where they have a local code amendment:
<https://codelibrary.amlegal.com/codes/san_francisco/latest/sf_building/0-0-0-84935>

300.4(I)  Add the following section:
 (I)   Subject to Physical Damage. Premises wiring systems installed less
than 2.44 m (8 feet) above a walking surface or finished floor are
considered subject to physical damage.

As far as I'm aware otherwise, there is not a specific definition
specifying 8' for physical damage in the broader NEC - I think it's just up
to the AHJ.
