f. Fence Security - Barbed Razor Wire. Bond security wires to the fence post using 6 AWG bare stranded tinned copper conductor and UL listed bonding connectors. Bond across terminations in the security wire using a short piece of the security wire material and UL listed bonding connectors at the same locations in 5.3.8.1 (a), (c), and (d).

g. Fence Wire Fabric - Chain Link. Attach metallic fence fabric to fence posts with wire ties of the same material.

h. Proximity to a Facility EES. Portions of a fence that are located within 22 ft of a facility EES will be bonded to that EES with a 4/0 AWG bare copper conductor exothermically welded to a fence post ground rod.
