PC Peripherals SHOCKING Cabinet - HELP!!!

In that case you will have to talk to the owner with some tact. If you are living in a flat in some apparment complex with proper internal wiring and all, then they have the obligation to provide proper earthing to your house. Normally there are some safety regulations for such buildings and they have to follow those.

hey

I tried the bulb test.

So when i put the wires in live and neutral - the bulb glows.

but when i put the wires in live and earthing/ground - the bulb does not glow.

Same case with other sockets in my room.

when i tried the same test in the living rom - Poof - the fuse tripped and the entire house electricity was shut down.

after that i didnt try it agian.

I have called the electrician now. lets see if he can fix it as all the wires are concealed in the walls for this house.

See. I have told you 100 times, its GROUND Problem. Should give me REPU for it.... hahahah

Lets come to the topic.

You should ask your OWNER. If he/she agrees.... fine. else take a long long single copper wire with white plastic jacket. One end the main computer switch board's GROUND-Point, other end, to a source with GOOD GROUND-Point. Actually, instate of a switch board you are just making a bridge of GROUND-wire. :hap2:

Don't forget to do the Bulb-test, only 10000% realiable test to check the GROUND. and yes sometime it fuses... after all you are actually shortening the circuit. Take a HIGH WATT bulb.

I can understand the single core copper wire, but why only white plastic jacket. Wont blue, green, red, blah... blah... ones work? :rofl:

The testing phase is already complete and it has been confirmed that there is no earthing. :)

What the heck is that... :what?: :crazeyes:
 
I think the first thing to do is to temporarily move the computer to a room where the Earthing was found to be OK and confirm that there is no shock from the cabinet. Do this before you start making holes in walls.
 
This has been a really long thread for what should have been a simple matter.

First of all Deejay is right. Get rid of the leakage first.

Basically, the zap you get is due to a combination of two reasons: excessive leakage within your system and lack of earthing. Both need to be tackled. Deejay has given you the right approach regarding the first and you already have several things suggested for the second.

I must warn you that it is tempting to ignore the leakage problem and provide a good earthing but that woul be a faulty approach for the following reasons:

1. Somewhere in your system the root of the problem has remained unresolved and could get worse over time like the transient suppressor already mentioned. Apart from the transient suppressor an SMPS also has capacitors that are meant to filter common mode line noise. These could also be leaky.

2. When you bypass such leakage by providing a good earth connection, if your house wiring has an ELCB (Earth leakage circuit breaker) the elcb will keep tripping.

3. If your earth connection further downstream ever gives way, your system's leakage will endanger many more people who may have their earth connection there. For instance someone who is ironing clothes with an electric iron connected to the same faulty earth where your system has been connected.

if you cant find any outlet at your place, try the neighbours place :eek:hyeah:

Another possible culprit is the ferrite transformer itself that could be leaky.
First disconnect the power cable to the monitor and check whether the cabinet still zaps you. You will be able to find out whether the leakage is in the monitor or the system cabinet.
You have mentioned that the SMPS was switched on stand-alone and checked for leakage. It is possible that you didn't see any leakage because the earthing at the dealers place was good. So it does not eliminate the main smps as the source of the leakage.
I once more recommend that you fix the source of leakage first and then settle the earthing issue.
