  HAL existed in 2001.  But in 2016, he still does not exist.  Even Einstein could not explain that.

Nothing has passed the Turing test.

  And numbers that say why.  For example, how many mistakenly believed a wall receptacle safety ground is earth ground?  How many knew that a minimal 'whole house' protector is 50,000 amps.   How many knew robust protection exists inside appliances?  How many knew that a plug-in protector can...

  Not a totally moot point.  If a 'whole house' solution has been compromised (ie protector failure, disconnected earth ground, etc), then a 'primary' protection layer might still provide sufficient protection.  Hopefully that protection layer has earthed sufficient energy. Otherwise that...

  None.  Then a plug-in protector does not compromise protection inside nearby appliances.  Then fire is not a threat.  Figure 8.  A plug-in protector earthed a surge 8000 volts destructively via some nearby appliance.  These threats do not exist if a plug-in protector is used with a 'whole...

  So you are saying engineers who did the analysis lied? Or that California lightning does not cause catastrophic damage?  Why do you believe anything inside a transformer will stop what three miles of sky cannot?  Nobody except you said anything about 'stopping' lightning.  Any protector that...

  With disrespect for your IEEE citation, you again contradict what both I and IEEE have said repeatedly.  IEEE and I are in complete agreement.  You did not read what  the IEEE says.  Time to admit to brainwashing by APC advertising.   Why did APC sell some 15 million protectors knowing those...

  Outside of San Francisco,  lightning literally caused an entire radio station to explode.  A transformer that connected 33,000 volts to 240 distribution was not properly earthed.  Lightning created a plasma path (a direct connection) from 33,000 volts to 240 volts.  That transformer even...

  No plug-in (power strip)  protector is earthed.  Wall receptacle safety ground clearly is not earth ground for many reasons.  Including one posted repeatedly: low impedance (ie less than 10 foot).   Listed previously were many manufacturers of integrity (...

Why?  This company finally admitted to selling some 15 million protectors that must be removed immediately.  Catastrophic failure in their protectors was creating fires.  We had noted this problem years prevoiusly.  But since APC was selling near zero protectors with a massive profit margin...

  What was I saying all along - from the very beginning?  Primary issue of grounding was repeatedly defined by "single point earth ground" and 'layers of protection'.  What defines each 'layer of protection'?  Earth ground.  What must harmlessly absorb hundreds of thousands of joules? Earth...

Those who are technically incapable of solving problems or learning something new must do what they only understand - attack the messenger.   Others who prefer to learn can appreciate why the OP had damage.  Wires entered a structure without making a low impedance connection to single point...

  A telco CO suffers about 100 surges with each storm.  They replacing tens of thousands of protectors with each storm?  Of course not.  But that is what you have claim.   Everything weakens with age.  So parts are sufficiently sized and properly earthed to survive direct lightning strikes even...

Defined was a minimal 'whole house' protector number.  50,000 amps.  That protector is over 100,000 amps. So it is better than a minimally acceptable protector that sell for about $60.   'Whole house' protectors come from companies known for their integrity including Intermatic, Square D, Ditek...

  IEEE *defines* all type of protectors.  IEEE only *recommends* some with numbers.  Properly earthed protection would do 99.5% to 99.9% of the protection.   IEEE recommendations.  From the IEEE Red Book:   What does not have that earth ground?  Plug-in protectors.  IEEE *defines* plug-in type...
