QuoteThat ignorance for which you have no words is a fair description of your own.

picowatt - TK - Magsy - all of you who have posted here regarding this issue - In South Africa and due to the haphazard standards applied by ESKOM - we ONLY have a 220 volt power supply sources at our homes and all our plugs and are subjected to random power surges that are known to fry delicate machinery.  Not even earthing can prevent that damage.  It can only LIMIT that damage.

And picowatt I am intrigued with your 'chassis to ground' which SPECIFICALLY means that you DO tie your machine to ground.  If we in SA relied on that we'd have FRIED our machines long before it found that PATH TO GROUND. 

All this pretension.  And everyone anxious to show off their superiority.  It's the art of spin - applied with the energy of vigilantes - to stroke your own ridiculous egos.  Such bombast. Thankfully it has NOTHING to do with science.  And EVERYTHING to do with 'tarring and feathering'.

Your discussion above is not even applicable to the subject matter at hand and some of it doesn't even make any sense.

The above statement doesn't even make any sense and I am not going to bother to explain anything to you.

Nor does the above statement make any sense either.

Bullshit - the discussion was about the real truth and not the ridiculous and nonsensical ASSUMPTIONS that you are making about grounding issues.

You need two years worth of full-time instruction just so that you will be able to tread water and understand what is going on.

Of course one of many ironies with the massive and exhaustive NERD testing over months and months - a dynamic team in action - is that apparently nobody ever thought of putting a $20 multimeter in series with the main loop to see if there was a measurable current flow.  They played with a $10,000 digital storage oscilloscope for months and never thought to measure the current with digital mutimeter that can practically be found at the bottom of a Cracker Jack box.

I don't know what a Cracker Jack box is - but I do know that if you applied a digital multimeter to measure the voltages that manifest at the frequency of our oscillations - then its results will not be dependable.  If it's a fairly dependable DMM it'll give a 'fair' average.  If you apply it's ammeter function - it will be ENTIRELY out.  If you get one with the required bandwidth - then you've got a sophisticated and EXPENSIVE machine.  A DMM found at the bottom of a Cracker Jack box - whatever that is - is not likely to be even partially up to par - if, as I suspect, that means that it's cheap and readily available.  And thankfully we DO NOT rely on measurements that are made by substandard machinery.  We leave that to the likes of you - your erstwhile 'team' and to this new team 'vigilante' led by TK aka Leon.

So you keep saying.  With less and less conviction.  It's intriguing.  Especially your definition of the 'real truth'.

I am NOT interested in YOUR discussion.  I've already explained that it's just a lot of hot air and bombast.  I am simply anxious to advise our readers why it is that the GROUND PIN of our PLUGS are required.  And why it is that without the GROUND PIN we will be exposing that machine to UNDUE RISK.

Do you not use a third wire gnd/earth return on your AC system?  I looked up connectors and it looks like you use three prong plugs.

With 120 or 220 in the US requires all exposed chassis metal to be connected to a separate ground path to the mains, unless the device is rated as "double insulated".  The neutral is not a permissable chassis ground.  Near a water source (sinks, etc) we also now require GFI breakers or retrofitted sockets.

No superiority intended, a question was asked and an answer was offered.

'twasn't even directed at you.
