PC-Case conducts energy

[Lucien Nunes]

At this stage the socket outlet is not the prime suspect. The plug-in tester is not a thorough test, however it does indicate that something at earthy potential is connected to the earth terminal. Neutral, earth or anything near either of them is likely to remove the PC leakage current so even if there is a wiring error and no RCD, he would be unlikely to get a tingle. Using the principle of Ockham's razor (the simplest solution is likely to be correct) the fault probably lies in the ground connection to the PC PSU which can be checked easily first, and the socket investigated if the fault is not found here.

FWIW the OP is in Germany so the socket will be Schuko, non-polarised but with reliable side-contact earthing.

Repeat.
The Suckit n See type Tester shown in does not verify neutral earth reversal.
OP describes himself as "new to this".
He also gives a good description of an AC touch voltage appearing on the case of his equipment.
He has asked how to measure what the touch voltage is.
He is new to this.
PLEASE DON'T advice him to carry out live testing with a multimeter

He already has the pc powered up. It is very likely to be leakage current. The basic testing I have proposed exposes him to no more danger than he is exposed to already. I didn't advocate taking anything apart, or measuring at live terminals.

I am a big believer in safe working.

On this one I don't mind being wrong.

To me, I would see this as a fault to earth. I would get a electrician or some computer engineer to take a look.

Your plug system is not earthed.

 

[DPG]

Your plug system is not earthed.

Impossible to say from info given.

by experiment I can confirm, without an earth connection 107VAC on the case of my PC, neutral and earth swapped 0v on the case.
so I stand corrected.

all PCs should be electrocuted...... oops thought thread was about politically correct.
