Hi Phil

I am a "portable deisel eclectric plant operator

This is my experince with electrical codes in Canada:

If you conect a ground wire it the fashion as you say you will have a LIVE
ground and is not allowed by electrical codes

Neutral or white wires are LIVE wires

Older houses do not have to be grounded and it is not required untill you
touch the electric sevice anywhere then you have to upgrade the whole house
to modern standards 

Colours and number of wires:
1 White-  Neutral conected to power pole
2 Black-  Power   conected to power pole
1 Green- Ground conected to metal power panel 
                               and to a ground stake in the 
                               ground outside of a house
Voltages
white to black  110 - 120 volts
Black to black 220 - 240 volts

Green should have no voltage when checked to a white wire

Green WILL show voltage when check to a black wire

Green connected to white creates a short circuit and is not alllowed

Green is used to drain any volatge that is leaked to ground

A spike in voltage when it is put though a power bar will go to ground and
is disapated.

You suggestion will put the spike into your computer and poof you have Don's problem

Solution is to create a ground though an extension power cord. This way you
do not touch the house power system

It is a hack but allowed. you can but extension and adapters with extra
ground wires haging off of them
