You could possibly safeguard them from dampness by making use of a rubber hose, size of backyard garden hose or PVC pipe. Location the cable and link details inside of this sheath to shield the modest space.
The conductor cable which is meant to carry lightning currents within the strike position (air terminal) properly to the ground rods and ground.
The Franklin Rods have been uncomplicated: a pointed iron spike 8′ to 10′ tall having a gilded suggestion (to avoid rust), mounted to the very best place of the building. The lightning’s path from storm clouds was thus facilitated (although neither straight captivated nor repelled), deflecting it faraway from the composition, into the rod, after which you can down a reduced-resistance brass wire for the earth.
Should you be applying air terminals of 24 inches tall or more previously mentioned the world being protected, you may spot Those people rods no more than twenty five ft apart.
Specifications demand the interconnection of cable downleads to reinforcing metal (rebar) in poured columns at the top and bottom of every run making a identical effect, Despite the fact that this mechanical structural program will not be considered ideal for carrying lightning recent by alone.
