Grounding electrodes ought to be put in down below the frost line exactly where achievable. The products used for grounding electrodes must be appropriate to any alkaline or acid composition of soils for long lifestyle.
Tinned copper cable can be employed in the majority of conditions. When utilizing aluminum you need to still transition over to copper above quality having a Bi-steel connector (section variety M3).
Franklin later prolonged his lightning-rod idea to ships, including British warships, which were inevitably outfitted with anchor chains that stretched with the major in their wooden masts to The ocean.
Lightning Security Conductors Lightning protection conductors are major-duty copper or aluminum braided cables that interconnect the elements of your lightning protection procedure's roof network and likewise create several paths on which lightning current can securely journey to the bottom.
Try this by digging a two foot deep hole to begin with. In a place where by depth gets a problem, it's possible you'll use ground plates.

Reinforcing steel or rebar is just not acceptable as a opravy hromosvodu Praha substitute for cable conductor, but Every cable downlead has to be bonded on the structural framing at the very best and base of every vertical run. All strike termination devices should have a minimum of two paths to ground to separate the lightning together many paths, Hence the smallest constructing needs to have two downleads least.

The final product ought to incorporate the bonding with each other of separate grounding electrodes of various methods.
“In case you at any time see a unpleasant-searching cloud up there, you might think, ‘I’m ok, it's possible there’s no lights,’” says Dwyer. “But it could be that that storm has become earning lightning for a while.
