Lightning rod cable. A copper cable is used to attach the lightning rod for the grounding material. It ought to be of adequate measurement to handle the electrical existing developed through a lightning strike.
You can find five components that must be set up to provide a good lightning safety system. Strike termination devices must be acceptable to simply accept immediate lightning attachment and patterned to simply accept strikes ahead of they arrive at insulated creating components. Cable conductors route lightning recent in excess of and through the construction, without damage, amongst strike terminations at the best and the grounding electrode system at The underside. The under grade grounding electrode procedure will have to competently transfer the lightning to its final desired destination faraway from the structure and its contents. Bonding or maybe the interconnection from the lightning security program to other interior grounded metallic techniques need to be accommodated to remove The chance for lightning to sideflash internally.
