But don't you have toddlers at home?  Please, please DON'T ignore this problem - get it seen to before you end up with a tragedy on your hands...

Of course I never imagined that you would let your kiddies near the cooker - I was thinking more if something happened to thier Mum! Sorry if I seemed to be pedantic...

Yep - tingle's the word. Off the laptop and dishwasher most usually. Not the cooker yet, but give it time. Not entirely sure earthed UK 3-pins are the answer. Laptop has one; cooker has an Italian 3-pin I fitted. Bill gave me wiring instructions on a thread when we got here. I blame him.

yep, it's more like s tingle than a full shock and thinking about it, i get shocks off my slaptop and the freezer, both in the kitchen and i am afraid i am prone to touching things with wet hands, and yes, it is only me, no one else, i also get a shock from the trampoline, but that's another post waiting to happen...LOL. i asked because in the uk even the sinks are earthed, when we get the new electric mains box put in we are going to earth that, we were told to connect an earth cable/wire through the house into a pole stuck into ground, this is quite acceptable allegedly, physics teacher told us. i just thought someone would come up with something like....'attach an earth wire from the cooker to a pole stuck in the ground outside for now and then transfer it to the mains box when the new box goes in' but if it's normal even if the electrics are new, i'll wait untl we renew the wiring and get my rod in the stable, next to the mains box.

i just found this The most common (and most accepted and preferred) method of grounding the main service panel is by way of an 8' ground rod driven into the earth....and in some cases....2 rods...6' apart from each other. Once inside...the majority of authorities or inspectors also want the water pipe (street side before the meter...and after it) bonded to the panel as well. This is more of a bond...then a ground - although it is sometimes referred to as a "supplemental ground"...and is used only in the case of metal water pipes....so some wells are excluded if they are in plastic to the house. Years ago...the street side metal of a water main was allowed to serve as the main ground...but the Codes have changed since then.

You need to sell this: sci-fi couldn't make it up. My dishwasher of yore actually gave me a very nasty good morning jolt, so I sold the house. Took care of that problem! I like Alyson's idea: as long as we don't touch our damp hands with our laptops in situ we should be ok. On the other hand, ain't it all 'bout da BUZZ? |

I remember an electrician telling one of my neighbors that the ground rod(s) must be driven into the ground outside the building and the one he had driven through a concrete floor no longer met the Nat'l Electrical Code. I seem to remember something about the soil and moisture. |

I always did wonder why that was. Actually...thinking about it...I still do.

If you are being shocked by your appliances and already have a properly grounded system (w/ a grounding electrode, usually the water pipe, and a supplemental grounding electrode, usually a rod) then there is probably a short in the cooker that is allowing the metal exterior to become energized. If you don't have a properly grounded system, then it is also possible that the poles are reversed (one of the hots and the neutral) at the main panel (which is where the bonding of the neutral and the ground is supposed to be) and the exteriors of the appliances are being energized throughout the house because of this.... I would call a reputable licensed electrician ASAP and have them trouble shoot the problem. Don't wait and try to figure it out yourself, call an expert! It only takes 3-5 milliamps coursing through the wrong ground path (your heart) to kill you....

I would go along with the post from Gioele, don't mess around with this. Electricians are not that expensive. A shock from any applicance no matter how small the shock means there is a problem. Get it fixed before wet hands and wet feet turn a little shock into a big one. Reminds me of a trip in our camper, my son said he got a shock touching the camper shell. A little investigation revealed that the socket the power cord was plugged into was not getting grounded due to corrosion in the outlet. Now I tend to check everytime I plug in.

Yikes! Grounding should not be made with water pipes or you'll get shocked also through the water/faucet. Old houses might have this grounding system, but it is definitly not recommendable. |

I am not talking about attaching a wire from your outlet and hooking it up to the water pipe as a ground fault return path, I am talking about using the metal incoming water pipe to your house as the grounding electrode (and using a supplementary one) that is electrically bonded with it and the neutral at the main disconnect. This is standard operating procedure in the US. With all due respect, as I see that you are working on your electrical engineering degree, I don't know how they do it in Italy, but in the US, where I am a certified master electrician, as of the 2002 NEC (we just switched to the 2005 here in CA, we're three years behind in adopting the National Electric Code) you can use either the water main (if it's metal and the proper length in the ground) or a Ufer grounding electrode (tied into the rebar of the foundation) and a supplemental grounding rod as the grounding electrode system. This ties in with the neutral at the main disconnect (can also occur at the meter) and the cold water pipe, if metal, is required to be bonded to the gas and the hot water pipe (usually at the hot water heater). If you don't bond (also known as grounding or earthing) your water pipe and somehow an energized conductor touches the water pipe, then your whole water system can become electrified. This is very dangerous...
