Electricity at both ends of a wire is same? Classic ignorance of how electricity works. Makes one a victim of propaganda. This victim then spends tens or 100 times more money on near zero products.

Code is clear. Wall receptacle ground is not earth ground. Stated multiple times with reasons why and numbers. Being in total denial, it escapes you.

Chassis ground is different from motherboard digital ground, is different from floating ground, is different from analog ground, is different from a lightning rod ground, is different from receptacle ground, is different from breaker box ground, is different from water pipe ground, is different from earth ground. Many can be interconnected. And are electrically different. Somehow that reality escapes you.

Assuming all grounds are same, then a lightning rod can be connected directly to a computer's chassis. That will protect the structure and protect a computer - using your reasoning. Reality. Obviously a lightning rod must connect to earth ground. But according to you, a lightning rod can be earthed to a computer chassis. Basic electrical concepts escape you.


OP asked about surge protectors. Many are so easily manipulated as to even recommend a plug-in protector with its near zero joules. A $3 power strip with some ten cent protector parts routinely sells to naive consumers for $25. An equivalent Monster sold for $85 or $100. Some refuse to learn what a protector or UPS does. In this case, one even assumed safety and earth ground are same. Profits are obscene when the electrically naive are manipulated by hearsay, speculation and advertising.

Informed consumers earth one 'whole house' protector. If anything needs protection, then everything (even plug-in protectors and UPS) need that protection. Informed consumers locate this solution (proven by over 100 years of science and experience) in a breaker box or behind an electric meter. A protector is only as effective as its earth ground. That means a low impedance (ie less than 10 foot) connection to earthing electrodes. This proven solution costs about $1 per protected appliance. Best protection is also least expensive. So that even direct lightning strikes cause no damage.

Ohhh okay. I get it now. You just don't believe that ground goes to .... Ground.

Wall receptacle ground connects to earth ground so that a receptacle, plug-in protector, and attached appliance are at 12,000 volts. Some call that a connection. Yes, current is flowing from wall receptacle to earth. And up to 12,000 volts is doing damage - because that protector is not connected low impedance (ie less than 10 feet) to earth. It is only connected to a safety ground.

OP asked about surge protection. Many use one due to insufficient electrical knowledge and that illusion that safety ground is earth ground. Some promote an ineffective (and obscenely overpriced) protector. It only averts surges that typically do no damage. And may compromise superior protection inside appliances; make damage easier.

Another obvious urban myth is a surge when power is restored after a blackout. That surge also exists only in fables or where scams are promoted.

Plug-in protector has another idiosyncrasy. Due to its near zero joules, it has a history of creating fire. Another reason why informed homeowners (with two or three wire wall receptacles) earth a 'whole house' protector. And upgrade what actually does protection - single point earth ground.

Informed homeowner earths a 'whole house' protector. Easily scammed consumer uses plug-in protectors. Major difference. A protector is only as effective as its earth ground.

You are wrong. ... And a whole house protector doesn't exist.

Earth ground does not exist? Surges that do damage by connecting to earth do not exist? Numbers that define effective protection do not exist? Someone who did this stuff many decades ago does not exist? And now 'whole house' protectors from companies known by any guy for their integrity - such as Siemens, Ditek, Polyphaser (an industry benchmark), General Electric, Syscom, Intermatic, Square D, ABB, Keison, Novaris, Leviton, and Square D - do not exist? Why do we know? Apparently god, using the name ROM, has told us what to believe. He must be telling the truth. He said so. Clearly it must be true. Since only ROM exists.

Destructive surges (ie lightning) can be 20,000 amps. So a minimal 'whole house' protector (that does not exist) connects up to 50,000 amps to earth ground (that does not exist). Because surges, such as direct lightning strikes (that do not exist), must not even damage a protector (that does not exist).

OP should obtain and earth the only protector that actually claims to harmlessly earth hundreds of thousands of joules. That actually claims to protect from destructive surges. To even protect those 'near zero joule' protectors that sometimes cause fires (that we will be told do not exist). Of course that will be wrong because we do not exist. We were told what to believe - without even one reason to believe it. So it must be true.

Or the OP can earth a 'whole house' protector since that is how protection was done over 100 years ago - long before we were told it does not exist.
