[SOLVED] Earthing problem

[coolraveen]

Hi guys,
Currently the house I live, the earthing is not properly done and leakage is there, so I moved to this home temporarily, now I found out that improper earthing is done, after I got a slight electric disturbance which touching my pc cabinet, I immediately switched off my pc and kept it away, ( ran it for 2 mins max), would it have damaged my pc?, Should I de earth my pc now?

First - Your PC (or any other electrical device) does not need a "ground". The "ground" (earthing) wire is a safety feature that will only come into use after another failure in the system. The most likely cause of a small shock is static electricity leaving you and "grounding" through the cabinet. In this case you are the electrical problem and the PC cabinet has solved the problem by sending your excess charge to "ground".

Was this "shock" the only indication of bad wiring? has this happened multiple times ? Do you get shocked when touching the water tap handle ?


Second - Any damage that occurred would have been instantaneous. If the PC was not damaged immediately it will not be now.

One common way that "grounding" (earthing) is done improperly is to connect the ground wire into the neutral at a sub-panel or junction. This can result in some loads traveling the "ground". This will not damage your computer but is hazardous.

In my previous house the wiring was done before the codes required separate ground (Earth) wires. For my PC outlet I ran a separate grounding wire to a grounding spot (an outlet in an addition that had more modern wiring). You could also create a ground to a metal water pipe that leads underground.

Bro this is happening even after grounding the wire from the junction, by directing the current to the soil through inserting the pipe to the soil outside my house. By that way the electrician said this is a temporary way we can gound the circuit.

Now even after doing this I get that electric discharge from the pc cabinet.

I have a laptop too and there is electric discharge through the metal laptop lid.
My laptop seems to work fine as of now.

I have not run my desktop pc more than two minutes as of now.

So will this have damaged my laptop or pc? As it seems to work fine as of now, am currently only using the laptop, and not my pc, as it will cause damage to my pc.

I intend to change home in a two months time.
And moreover there is no electric while touching tap handle. Only happening through electric outlets

Sometimes, sliding in/out of your chair or just by simply walking on carpet and such can cause a build up of static electricity on your body. Then as soon as you touch the PC case (or any metal object that is large enough or is grounded) will likely give you a jolt as the static electricity dissipates. This is exacerbated by dry air, whether it's your naturally-dry climate or your A/C is doing too good of a job dehumidifying your place.

This is also a problem in my place when the A/C is running. What I usually do when I get off my chair is to touch the tile floor for a second using one of my bare foot. That will dissipate any stored energy slowly (tiled floor isn't quite a good conductor) and you won't feel anything. Doing so, I don't get a jolt when I try to slide open our aluminum door to the kitchen or touch a metallic faucet, etc.

If this is the case I will be happy, but seems like the grounding is very improper, as my laptop does not give the static discharge if I connect it somewhere else rather than my home. Thanks for your info bro
