After catching multiple sharks as in their usual routine, they caught this hog! After a couple of hours fighting this shark, they eventually get it up on their boat. It turns out to be the largest bull shark ever caught for mankind. There were two if the scientists on board and had a heck of a time getting this fish reeled in with the both of them helping. As the fish laid in their special docking system setup to harm live sharks as little as possibleâ¦ the men looked at the beast.
A lightning rod and its associated grounding conductors provide protection because they divert the current from nonconducting parts of the structure. Grounding is the act of connecting a conductor, or exposed conductive parts of an installation, to the earth. The grounding protects personnel from stray currents that could leak to the metallic enclosures. A lightning rod and its associated grounding conductors provide protection because they divert the current from nonconducting parts of the structure.
Grounding a tool or electrical system means intentionally creating a low-resistance path that connects to the earth. This prevents the buildup of voltages that could cause an electrical accident. True : False : 5. Grounding is normally a secondary protective measure to protect against electric shock. It does not guarantee that you won't get a shock or be injured or killed by an electrical current. True : False : 6. A service or system ground is designed primarily to protect machines, tools, and insulation against damage. One wire, called the neutral or grounded conductor, is grounded. In an ordinary low-voltage circuit, the white or gray wire is grounded at the generator or transformer and at the building's service entrance.
