Downleads or down conductors are The weather of the principle conductor system that usually convey the lightning from your roof stage system into the grounding technique. This will include cable conductor, or qualified continual metal framework of 3/sixteen” thickness or greater, or a mixture. Reinforcing metal or rebar is just not acceptable as an alternative for cable conductor, but Each individual cable downlead has to be bonded to your structural framing at the highest and base of each vertical run. All strike termination equipment have to have at least two paths to floor to separate the lightning together numerous paths, Therefore the smallest making have to have two downleads minimum amount.
Much has improved Because the early times of lightning security, when it absolutely was extensively thought that the glass balls adorning lightning rods were an indicator of whether or not the rods had been operating correctly.

This does not suggest which the resistance of the bottom connection should be lower, but alternatively that the distribution of metallic within the earth, or upon its surface area in Excessive conditions, shall be such as to allow the dissipation of the lightning discharge without the need of causing harm.
The most effective methods consist of an extensive wire network laid around the surface area in the rock encompassing the developing to which the down conductors are connected. The resistance among this sort of an arrangement and earth could possibly be significant, but simultaneously, the likely distribution with regard to the building is significantly similar to while it have been resting on conducting soil along with the ensuing protective impact can be considerably precisely the same. The lightning protection grounding electrode method serves to take the lightning into no matter what soil strata exists, and route it far from the structure.
