2-prong to 3-prong
------------------------------------- Hi, I install home computers, and recently I was in a beautiful old house to install a machine but found there were only two-prong ungrounded outlets. I didn't know what else I could do, so I removed the grounding prongs from a six-splitter and plugged that into the wall. I plugged the computer and the LCD display into the six-splitter. Can someone tell me if this is dangerous and if so how dangerous? Thanks very much. chuck ##-----------------------------------------------## Delivered via http://www.thestuccocompany.com/ Building Construction and Maintenance Forum Web and RSS access to your favorite newsgroup - alt.home.repair - 310791 messages and counting! ##-----------------------------------------------## |

Dangerous to the computer- probably to definitely, depending on how house is wired, and how often power goes flakey in that part of town. Did you tell your boss what you did? Did you pull a cover and see if the feed wire had a ground, or perhaps was grounded through metallic conduit? Cure may be as simple as switching the outlet for a grounded one, hooked up properly. A gfci could be installed with the appropriate label as being non-grounded. PROPER cure is to get an electrician in there- if the house wiring is marginal, best cure is to snake a dedicated string back to service panel, just for the computer station. If the people use this computer to make a living, a small UPS box is probably indicated. -- aem sends... |

If the entire house has 2 prong outlets. the easiest thing to do would
be to install GFI breakers to protect the entire circuit ( except the fridge circuit). |

Make your installation using the adapters and instruct the customer to contact their electrician to provide a grounded outlet for the installed equipment. |

If a power wire inside the computer touches the (metal) case of the
computer, the case can become energized. And thus, a shock hazard to the people. With a grounded system, the power goes through the ground wire back to the earth. With the ground prong cut off, the power goes through the person, electrocuting that person. -- Christopher A. Young Learn more about Jesus www.lds.org .. "chuckferguson" wrote in message ...

You may have just screwed yourself. Lou |

Just get the little gray adapters that convert 3 prong to 2 with a green wire that has a spade lug on it. Plug the power strip into the adapter, connect the adapter green wire to the middle screw on the wall plug. If it's grounded it will be grounded, if it isn't it isn't. Not your problem. Plug the adapter into the 2 prong outlet. Point out to the owners that this is not the best connection but they should be used to it since they must have had to do this all over the house. Check and see how they have their microwave plugged. BEST reply!! Lou |

Adapters. That's what they're made for. Plug the surge strip into a properly grounded adapter. Most surge strips have a light to tell u if it's grounded anyway. An adapter isn't going to provide a ground. All it will do is connect the power strip's ground to the screw of the outlet which won't be grounded. |

Maybe that applies to the computer you keep by the side of your bathtub. Not only that, but power supplies don't connect the mains to the ground. The chance of the ground being anything but high impedance is rather unlikely. The ground is there for the unlikely chance that a broken wire inside the computer could come in contact with the case and this is extremely rare. Don't take the computer into the bathtub and there won't be a problem. |

Same here in MI and in IN where I used to live- from late 50s to mid 60s, grounded romex and boxes with 2-hole outlets was quite common. Made converting the 2-hole outlets in this place easy- just made sure the copper wound around the romex under the clamp was shiny, the clamp was snug, and ground the outlet to the box. Magic outlet meter is happy. Yeah, I know current code regards that as borderline, but I wasn't about to try and unwind that 45 year old copper to run it to the screw on the outlet. It does get brittle. Putting the ground wire under the clamp was SOP by all the electricians when I was growing up watching them. They said it made for a less crowded box. -- aem sends... |

If one of those two wires come lose and goes to metal, it is pretty easy to see.

I don't care how much metal is inside, if the outer case is plastic that's pretty much the final word on shock hazard. My computer case is metal, and painted black. This paint lowers the chance, even more, that the case would electrocute you, but grabbing the thumb screws at the back of the computer could still kill you. I don't know if it has ever happened, but that doesn't mean it can't. With a proper ground, the chances are even lower. That is what the NEC is shooting for. |

Yet you're willing to say "That's assuming the case is metal, of course, ** which it most likely is not.**? My similiar survey show the exact opposite. In fact there's not a plastic case in sight, at work or at home. Unless someone comes forward with some documented percentages, it's nothing more than an assumption that any given computer case "most likely is not" metal. one of the crowd who thinks Google invented usenet There ya go, making assumptions again. Just like it's a stretch to assume that any given computer case "is most likely not" metal, it's quite a stretch from "he uses Google groups" to "he thinks Google invented usenet". It's just possible that there are valid reasons for using Google- groups . Perhaps one's corporate-installed image does not allow for the installation or use of newsreader applications or personal email accounts. If one didn't use Google groups in those situations, one couldn't break up the work day by engaging in such witty banter with other members of this group. ...didn't escape my keen observation or your ability to jump to conclusions. |

Two prongs does not always mean no ground. In many old homes the outlets are connected via metal conduit which provides a ground. Without checking you can not be sure it is grounded even if it has a metal conduit. Since there are so many variations around and in older homes there often are non-code wiring, I suggest that to be safe, either assume there is no ground, or have it professionally checked. |

Not Google itself- the place would grind to a halt without it. Just the groups. The only way I can bump any personal or fun stuff during the day, is to detach from the LAN, fire up the wireless, and get out through the non-trusted wireless nodes they keep running in the conference rooms so visitors can do their demos. They block anything that looks like personal mail, news feeds, chat sites, hobby sites, forums, etc. Hell, I can't even hit my work email from home any more, unless I take the company machine home and VPN in. They even turned off the web mail interface. -- aem sends... |
