Specifications involve the interconnection of cable downleads to reinforcing steel (rebar) in poured columns at the highest and bottom of every operate developing a equivalent effect, Though this mechanical structural process isn't deemed suitable for carrying lightning existing by by itself.

At the inception of the lightning strike into a system, there may be a right away rise to 1,000,000 volts at outstanding components touring to 0 volts at earth ground. Another independently grounded making program in shut proximity to lightning security elements could well be at 0 volts, Therefore the normal inclination is for many or every one of the lightning to leave our present-day carrying system and flash above on the alternate floor route.
A braided copper or aluminum cable manufactured for lightning units connects the rods and runs into the ground to dissipate a cost.
