Do PC's cause earth leakage ?

A friend, (a qualified and VERY good electrician), phoned me today and asked
if I knew anything about PC system boxes causing earth leakage ? I told him
I didn't.
He continued to explain that the owners of a building that he had rewired
a short while ago recently contacted him to inform him that the buildings'
main RCD was tripping out. His men, (also qualified electricians), upon
investigating this fault discovered that all the RCBO's in the buildings'
main consumer unit, (main fuseboard or distribution board if you prefer),
had been replaced with plain mini-circuit breakers. i.e. no longer RCBO's
(an RCBO is a combined mini RCD / mini circuit-breaker ). The purpose of an
RCBO is to disconnect mains power to an individual circuit in the building,
should there be an earth leakage exceeding the milliamp trip value on that
individual circuit, rather than tripping out the whole mains supply to the
building at the main RCD.

He 'phoned the owners of the building to ask why the RCBO's had been
replaced with plain circuit breakers and was told that "they" had been told
that their computer room had been tripping an RCBO because PC's always
produce a "leakage to earth."

I told my friend that this was the first I'd heard of it, and it sounded
like a load of rubbish to me but, I would post a message here, and on the XP
hardware NG to see if anything was known.

phew !

SO, ....has onyone in here ever heard anything about PC system boxes
causing, or suffering from earth leakage that would cause "normal" RCBO's to
trip !?

Any device that has an earth wire can cause an earth leakage,
if defective. All it takes is some conductive element - a loose
wire, a fluff of damp dust, a dead moth - to bridge the active
supply wire to the power supply's case. It could also be the
power outlet in the office wall itself. A trained electrician should
be able to isolate the culprit.
 
In a word...NO!

That's like saying that if you stand to close to a microwave oven, you'll
get radiation sickness. It'a an urban myth.
 
More importantly by replacing those RCD's (ground fault detectors) he may be
violating the local building code.
Put the RCD's back and look for the real problem.

Urban myth? HAH!! This phenomenon is real and well-documented by the
scientist who discovered it, eminent electronicist Dr. Gerhardt Von
Tinhatzen, seen here at his lab in Spüfsberg, Germany:

http://people.csail.mit.edu/rahimi/helmet/ali2.jpg

According to his research, it is not a "... true leakage to earth but just
the opposite ... the earth is actually leaking into PC's". According to
Tinhatzen this is evidenced by the dust we find on our monitors every morning
even though we just cleaned. The source of this leakage, according to
Tinhatzen, is the ionization of ground soils from extremely low frequency
radio waves passing through the earth emanating from a specific spot
somewhere underground near Crawford TX, USA. Tinhatzen says this
electromagnetic phenomenon resonates at exactly the same frequency as
experimental brainwave scanners, code-named WGA, which the American National
Security Administration claims does not exist.

You mean Dr. Gerry Stanushatten?
 
I turned on my Dad's computer one time and all the power in the neighborhood
went out before I got to the Windows screen.

Know the feeling, some days. (In all honesty, it took me a moment to
recognize the sarcasm, as well.)
