EMERSON KJ4001X1-CG1 Optical fiber interface board

Content introduction

This guard wire also provides a low level of protection against transients induced on lines by close proximity strikes as well as nearby cloud-to-cloud discharges. The guard wire must be located above and parallel to the service conductors. To be effective, the height of the guard wire must not allow a circle with the radius of 100-feet tangent to the guard wire and earth to touch the service conductors to be protected per NFPA 780. The guard wire must extend from the secondary of the service transformer for the facility to the facility service entrance fitting. Also, at each end the guard wire must extend to, and be bonded to, an effective earth ground or to the earth electrode subsystem of the facility. When the distance between the service transformer and the facility service entrance exceeds 250 feet, the guard wire shall also be bonded to a ground rod. Since the guard wire and the earth electrode subsystem are usually comprised of different metals, exothermic welding is recommended.
