10 Simple Power Outlet, Grounding Galleries - Grounding of metallic cased system is most often achieved for safety reasons, instead of esd protection. If a fault occurs within the system that places line voltage on the chassis, the voltage is shunted to ground and could journey the breaker at the circuit. This saves you from unintentional electrocution.
It is extraordinary that they are the usage of the term "esd" because what they are speakme approximately is the sort of fee that would include a lightning bolt. Sure, technically it's miles esd, however no one but we professionals might ever think of it that manner. As an engineer who designs integrated circuits (chips), i'd name it "rate coupling" or in reality "to shield towards close by lightning moves," however whatever floats their boat.
A piece of detail to help you recognize the problem... The passage of strength causes a magnetic subject. When that magnetic field passes through every other wire, it "couples" rate onto the cord, which means energy flows way to that magnetic discipline. That is how electric powered vehicles paintings. Lightning has so much power that even a close-by strike can couple rate onto your housewiring, telephone wiring (if you nonetheless have any) or onto the wires used in your cameras. I honestly had this appear when i lived in texas. A single bolt burned out smartphone wires in the walls of my house and blew the statistics port on a printer. Quite cool for some thing you can not genuinely experience as a person (properly, it became cool until i my spouse told me i had to repair it. Geeks...).
Inside the professional audio and video fields, the cheater plug has been diagnosed as a serious protection hassle. Its informal use as a way for keeping off floor loops in analog audio and video signals (to do away with hums and buzzes) is dangerous. invoice whitlock, president of jensen transformers, writes, "in no way, ever use gadgets together with three to two-prong ac plug adapters, a.Ok.A. 'Floor lifters', to solve a noise trouble!" whitlock relates how an electrical fault in one tool that is related to its energy supply thru an ungrounded cheater plug will result in dangerous, excessive cutting-edge flowing via audio or video cables. Whitlock notes that in 1997, client audio and video device electrocuted nine people..
